[ovirt-users] Ovirt 4.04 unable to umount LUNs on hosts

[Andrea Ghelardi]

Hello ovirt gurus,
I'd like to bother you with a long lasting issue I face.
My (new) test setup (not production one) is running ovirt 4.04 hosted engine on 
a Dell R510 server connected to SAN Compellent SC040 via iscsi.
All systems installed from scratch following guidelines.
Ovirt hosted engine installed using ovirt-appliance.
Everything is working "fine".
BUT
We are unable to perform a clear LUN removal.
We can perform all actions from web interface (storage add, maintenance, 
detach, delete) with no error.
However, underlying device remains mapped to server. As a result, we are unable 
to unmap the LUN otherwise multipath fails, server fails, ovirt fails etc.

Steps to reproduce:

1)  Create LUN on SAN, map it to server -> OK

2)  Log in ovirt web interface, add a new storage targeting LUN -> OK

3)  Create disk, create VM setup VM, (optional) -> OK

4)  Shutdown VM -> OK

5)  Ovirt: Put storage in maintenance -> OK

6)  Ovirt: Detach storage -> OK

7)  Ovirt: Delete storage -> OK

Expected result:
Ovirt unmaps and remove device from multipath so that it can be destroyed at 
SAN storage level.
It should be possible to perform this action even when host is not in 
maintenance.

Current result: volume remain locked in multipath (map in use).
Trying vgchange -a n  and then multipath -f  removes device, 
but then it is automatically re-added after a while (???)

Please note: this is the same behavior we always faced also with our ovirt 
production environment.
Details attached. Volume to be removed: LUN 64

Any ideas?
Thanks
AG

[ovirt-users] how to remove a data center?

[Andrea Ghelardi]

Hello all,

I'm looking for an high level, approved, workflow to completely remove a 
datacenter and all its object.
Datacenter is made by 1 cluster, 1 server, 1 local storage, no VMs.
Hosted engine is on a different data center.
Everything is nicely working.

The administration 
guide<http://www.ovirt.org/documentation/admin-guide/chap-Data_Centers/> reads 
that:
"An active host is required to remove a data center. Removing a data center 
will not remove the associated resources."
Actually, I *want* to remove all associated resources and forget about them.

So... is it correct to:

  1.  put the storage in maintenance,
  2.  then put datacenter on maintenance
  3.  finally remove the datacenter

will this cleanup also related storage and server? Yes, no? other suggested 
actions?
Thank you
Andrea Ghelardi

As far as I can see from the screenshot the dwh does collect the samples, but

1. I see that you installed the full dwh. Did it work correctly in the past? 
Did you use the reports and was able to use them?
2. Please attach the ovirt_engine_history db dump and the dwh log and

Hi,

I've update our oVirt installation 3.6 --> 4.0 --> 4.1, everything went smooth 
except update some of the hosts which i could update after several hour playing 
around.

We greatly appreciate the dashboard in 4.1 but we see the information missing:

  1.  On the cluster block in the upper part we see the amount of clusters but 
no Status (N/A)

The reason there is no status there is that in oVirt there is no cluster status 
(look at the cluster main-tab, for example).
We only have statuses for objects like DCs, Hosts, VMs, SDs (well, maybe we 
have for some more, but not clusters...).
We decided to include clusters in the inventory part anyway, for user 
visibility, and provide access to the clusters main tab by pressing the link.



  1.  On the lower part at "Cluster Utilization" and "Storage Utilization" we 
don't have any information at all.

Where does this information come from? DWH service is up and running
The inventory part is taken from the engine.
All the rest is taken from DWH.
You can start with sharing the engine logs here.
Shirly - any other logs or information you think is required?



Where do I have have to investigate further to find out what is missing/not 
working?

Let me know if you need further information.

Arsène

Re: [ovirt-users] [ANN] oVirt 4.1.1 First Release Candidate

[Andrea Ghelardi]

I somehow agree to this statement
While ovirt team is really doing an awesome job and ovirt is getting more and 
more polished at every release, a +100 critical bugfixes statement in a minor 
release tends to underline the flaws of 4.1.0 rather than the good things of 
4.1.1

Considering that

A)  there could be no test environment to check the upgraded version 
behavior and

B)  the upgrade itself may require more than a bit of effort when there are 
dozen hosts and multiple clusters involved,
this does not really encourage to always push the datacenter to the latest 
version available, especially if the in-production version is not misbehaving.

Please note I'm just sharing our company view and not blaming anyone.

Hi,

Is 4.1.0 still recommneded an upgrade from 4.0.6 in production or should we 
wait for 4.1.1 to comee out?

100+ critical bugs fixed sounds good but doesnt really encourage upgrading to 
4.1.0

Re: [ovirt-users] best way to remove SAN lun

[Andrea Ghelardi]

Hello Gianluca,
I have ISCSI SAN here and not FC but process should be very similar.
Correct operation is
Storage maintenance -> detach -> remove

Once you have removed the storage, Ovirt will release the sanlock.
Note that your server will still “see” the device and multipath will still list 
it as active.

You can now unmap LUN using your SAN manager.
If your multipath is correctly configured, device will “fail” but nothing else 
(multipath and server won’t hang).
You will be able to perform basic list operations via server shell without 
experiencing freeze or locks.*
Ovirt will continue to scan new devices so you won’t be able to manually remove 
them until you unmap devices from SAN manager.

If you need to remove devices manually, it is advised to follow this guide.
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/removing_devices.html

* If you do face command freeze etc, re-enable LUN mappings and check your 
multipath.conf

Cheers

Subject: [ovirt-users] best way to remove SAN lun

Hello,
currently I have a cluster of 3 hosts where each one has FC SAN connectivity to 
4 LUNs: 3 are already configured as storage domains (1TB, 2TB, 4TB), one is 
free, not allocated.
See here for screenshot:
https://drive.google.com/file/d/0BwoPbcrMv8mvRVZZMTlNcTQ5MGs/view?usp=sharing

At the moment the command "multipath -l" run on hosts shows all the 4 LUNs.

Now I want to do 2 things at storage array level:

- remove the 2TB storage domain LUN
- remove the 20Gb LUN not yet allocated

What is the correct workflow, supposing I have already emptied the 2TB from VM 
disks ad such?
Select 2Tb SD, then Datacenter subtab, then "maintenance", detach" and at the 
end "remove"?

I think I continue to see 4 LUNs at this point, correct?

Now I proceed with removal of lun at storage array level?

Should I select an SD line and then "Scan disks" to see refresh the SAN and see 
in multipath only 2 of them at the end?
Or any manual command at host level before removal from array?

Thanks in advance

Re: [ovirt-users] high number of IOPS from ovirt hosts

[Andrea Ghelardi]

Andrea,
Among other advices, I would also suggest you to re-deploy an host without make 
it an host-engine node.
It may be worth checking if HE service is responsible of so many IOPS as it was 
in my case.

Andrea,
I don't want to point any fingers but Mark Greenall faced some issues with 
Ovirt 4.06/4.1 linked to equallogic as well.
You may want to search posts in this ML with subject " Ovirt 4.0.6 guests 'Not 
Responding' " to see if you find any similarities.
How many storages are you presenting to how many clusters?
Also, are your nodes all Hosted Engine Hosts? In my old configuration, normal 
hosts read IOPS ranged from 50 to 500 while HE ones peaked even ~3000

Hi Andrea,

thanks for the insight; no I wasn't able to pinpoint the issue to a single

We have another cluster running 4.0.6 on a compellent as well and we haven't

I saw that happening on my HE hosts connected to a COMPELLENT SC040 when I was 
running Ovirt 3.5

All HE hosts were hammering the SAN with 2~4k IOPS each

Upgrading to 4.0.5 solved my case.
Are you able to check if IOPS are generated from a particular host or rather 
spread among all nodes?

Cheers
AG

Subject: [ovirt-users] high number of IOPS from ovirt hosts

Hi,

We've got a 8-host cluster running oVirt 4.1; each host is connected via iscsi 
to a EQL 4100 storage (2x).
Most of the VMs use barely any IOPS, however on our storage controller we've 
noticed a constant steam of reads, about 2000 IOPS; any idea what might cause 
the ovirt hosts to hammer on the storage so much?

Looking at iotop, it seems that systemd-udevd is being activated every few 
seconds (and its IO% is usually fairly high) so I assume this might be somehow 
related.

Thanks,
Andrea

Re: [ovirt-users] [Call for feedback] did you install/update to 4.1.0?

[Andrea Ghelardi]

Running ovirt v4.0.5.5.1 and not planning to upgrade to 4.1 yet.
We are happy with stability of our production servers and wait for 4.1.1 to 
come out.
The only real need to upgrade for us would be the added compatibility with 
Windows server 2016 guest tools.
… and the trim, of course, but we can wait a little bit longer for it…

Cheers
AG

Hi,
did you install/update to 4.1.0? Let us know your experience!
We end up knowing only when things doesn't work well, let us know it works fine 
for you :-)

If you're not planning an update to 4.1.0 in the near future, let us know why.
Maybe we can help.

Thanks!

Create a 99-whatever-you-like.conf file in /etc/ovirt-engine/engine.conf.d with 
the following content:

  SSO_ALTERNATE_ENGINE_FQDNS="thealias"

Then restart the engine:

  systemctl restart ovirt-engine

This setting is documented here:

Re: [ovirt-users] Ovirt 4.0.5 reporting dashboard not working.

[Andrea Ghelardi]

Hello all,
The issue has been resolved using the following approach:

Connect to the database:
# su – postgres
-bash-4.2$ psql -U postgres  ovirt_engine_history

### Listed table before editing ###
ovirt_engine_history=# SELECT var_datetime FROM history_configuration;
  var_datetime

2017-01-23 01:00:00+00


2016-10-03 12:43:20+00
2017-01-23 11:00:00+00

(6 rows)
###

### Editing table ###
ovirt_engine_history=# UPDATE history_configuration set var_datetime =
ovirt_engine_history-# date_trunc('hour', now())- interval '24 hour' WHERE 
var_name = 'lastHourAggr';
UPDATE 1
ovirt_engine_history=# UPDATE history_configuration set var_datetime =
ovirt_engine_history-# cast(now() as date)- interval '1 day' WHERE var_name = 
'lastDayAggr';
UPDATE 1
###

## Listing table values again (after update) ###
ovirt_engine_history=# SELECT var_datetime FROM history_configuration;
  var_datetime



2016-10-03 12:43:20+00
2017-01-22 00:00:00+00

2017-01-22 09:00:00+00
(6 rows)
###

A few hours after applying above commands, usage graphs appeared on the 
dashboard.
Thanks all
Andrea

Hi Andrea,

I believe that dwh not working is unrelated to what Liron mentioned.
Please open a bug on ovirt-dwh and attach the dwh log and ovirt_engine_dwh db 
dump, dashboard screenshot.

I will check what is the reason that data is not collected.

When a host is "connected" to a storage pool it monitors the active pool 
domains. When the domain monitoring results are reported back from the host, 
the first monitor run may haven't finished yet. In that case the returned 
status from vdsm is a dummy status and not an actual result - when getting such

We should change that log print to INFO rather then WARN.

Re: [ovirt-users] oVirt Guest Agent doesn't work in Windows Server 2012 R2 Standard x86-64

[Andrea Ghelardi]

My Ovirt guest services runs fine on W2012R2, but your ovirt tools is old 
compared to mine.
I would try to upgrade both ovirt tools and the engine to version 4
Since engine upgrade is advised but could impact your environment, I would try 
to download the latest ovirt tools from here 
http://resources.ovirt.org/pub/ovirt-4.0/iso/oVirt-toolsSetup/ and import its 
ISO.
You can then mount it to your guest via usual mean and “upgrade” your guest 
tools.

I do not remember if Windows 2012R2 is officially supported in Ovirt 3.6.7 
tought.

Hi Andrea

Triple Check

When the path is wrong we get this type of message:

"Windows could not start the Balloon Service on Local Computer.

Error2: The system cannot find the file specified."

But in this case, we get:

"The OVirt Guest Service on Local Computer started and then stopped. Some 
services stop automatically if they are not in use in use by other services or 
programs."

¿ Maybe a oVirt bug ?

Re: [ovirt-users] Lowering the bar for wiki contribution?

[Andrea Ghelardi]

I once tried to edit a broken link in current documentation and lost hope after 
10 minutes of efforts.

Being a sysadmin, I understand the fear of unknown/untrusted people accessing 
stuff and performing uncontrolled changes, but generally speaking I believe the 
majority of this community is not driven by 10y old cracker attitudes: I trust 
that the additional value provided by people will greatly overcome a few typos 
and errors.

Re: [ovirt-users] Request for oVirt Ansible modules testing feedback

[Andrea Ghelardi]

Personally I don’t think ansible and ovirt-shell are mutually exclusive.
Those who are in ansible and devops realms are not really scared by making 
python/ansible work with ovirt.
From what I gather, playbooks are quite a de-facto pre-requisite to build up a 
real SaaC “Software as a Code” environment.

On the other hand, ovirt-shell can and is a fast/easy way to perform “normal 
daily tasks”.

As long as we have good documentation about how to do things, can we have and 
support both?

I personally found that she'll isn't as useful as the python sdk. I usually 
open up ipython, load the sdk and interact with ovirt directly. This is faster 
and much more powerful than the shell could ever be.
okay, I suppose you to be a regular python user. Can you imagine how much time 
I spent just to understand how it works?
That is to say:

  *   installing pip and not pip3 because provided python-ovirt-engine-sdk4 is 
default installed to /usr/lib64/python2.7,
  *   installing ipython,
  *   importing the good modules,
  *   finding pertinent examples,
  *   understand differences between sdk3 and 4
  *   correcting some wrong examples
  *   adapting example to my need?
I can't see how it can be fast for the newbie.
What's the first goal of a CLI? to abstract all this stuff for the python 
newbie. If you want a easy-to-use webadmin for attracting a large public, you 
should provide easy-to-use CLI as well. Ovirt-shell was a part of my choice to 
use ovirt.
Yes we can learn to use SDK (I dit it), but I don't think a lot people who 
chose ovirt for simplicity wll use it except advanced users.
A new time, thank you for the great stuff for the great oVirt project, but I 
find there is too much distance between devs and users.
What do really think the community about this?

For the moment, my opinion is that ansible can't be as much convinient as the

Hello all,

I would like to kindly ask everyone who is Ansible or oVirt user for
testing of the new Ansible oVirt modules. For everyone who is familiar
with the Ansible and oVirt, this[1] describes the steps you need to do,
to setup oVirt modules library and start using those modules (Most of those 
modules will be available in Ansible 2.3, some of them are already in 2.2).

If you have any issue setting this up, please contact me, I will do the
best to help you.

If you have an issue, which you think is a bug, please open an issue
here[2]. Please note that Ansible is merging it's repositories, so since
next week it will actually be stored here[3]. If you are missing
anything please open an issue as well, or just contact me, and I will
do fix it. You are also very welcome to sent PR with fixes.

For those who don't have testing environment which can test against,
I've created an Vagrant project which will deploy you the oVirt instance
using Ansible playbooks. You can find how to use it here[4].

The repository also contains few examples[5], so you don't have to
copy-paste them from the source.

Thanks all for reading this and any feedback,

Re: [ovirt-users] NAS for oVirt

Hello Alex,
Specs you provided are a little bit vague. You don’t specify storage space.
Our main storage here is a SAN Compellent, but we do have also Synology and we

You can start searching this or comparable product

Hi all,

I am thinking to setup an environment with oVirt and centralized storage using 
a NAS that supports NFS and iSCSI.

The setup will be used to host approx 20 VMs. The VMs will be running critical 
services and not for testing. I have seen several from QNAP, iXsystems (freenas 
mini), ...
What NAS would you recommend for this setup?

Thanx,

Re: [ovirt-users] "Deactivating Storage Domain" error

[Andrea Ghelardi]

I remember facing a similar issue during decommissioning of my Ovirt 3 
environment.
Several tasks showed on GUI (and storage operations unavailable) but no tasks 
on command line.
Eventually restarting the engine VM cleaned up the situation and made the 
storage avail again.

[ovirt-users] Ovirt 4.0.5 reporting dashboard not working.

[Andrea Ghelardi]

Hello group,
I noticed that my dashboard does not show little colored "cubes" which show 
storage CPU and RAM usage history status.
Attached an image and logs from /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log
Here's an extract:

This is a quite fresh new installation, and restarting engine VM (hosted-engine

Ovirt is behaving normally.

Any clue?

[ovirt-users] ovirt 4.05 windows balloon service installation wrong path

[Andrea Ghelardi]

Hello team,
FYI standard installation of Guest tool on Windows server O.S. is somehow 
flawed.
It setups a windows service named "BalloonService" with path
C:\Program Files (x86)\oVirt Guest Tools\drivers\Balloon\w2k8R2\amd64\blnsvr.exe

Unfortunately, the real path created on filesystem is
C:\Program Files (x86)\oVirt Guest Tools\drivers\Balloon\2k8R2\amd64\blnsvr.exe
(please note the missing "w" after \Baloon\ )

The easy workaround is to run this command on a "run as admin" cmd shell:
sc config BalloonService binpath= "C:\Program Files (x86)\oVirt Guest 
Tools\drivers\Balloon\2k8R2\amd64\blnsvr.exe" DisplayName= "Baloon Service 
Ovirt 4" start= auto

I suggest to fix either the command that create path during installation or the 
one which setup the service

cheers

Re: [ovirt-users] [HELP] unmapping a deleted storage domain triggers crash ovirt

[Andrea Ghelardi]

Hello Nir,

Actually Ovirt3.5 host crashes even if the storage domain has been destroyed / 
removed from ovirt (hence ovirt has no knowledge of this storage and its mpath 
device and don’t bother about it). But I guess this is what you refer to when 
you write about “handling of unmapped luns”.

However, now that I caught you online, could you confirm that deleting an 
entity ( storage domain) from Ovirt should release the sanlock?
In other words: what is the supported way to delete an iscsi SAN volume?
My current approach is:

1)  Maintenance storage domain from ovirt4

2)  Detach+remove or just destroy storage domain from ovirt4

3)  Wait ~10 minutes

4)  Access SAN control panel and unmap+delete  associated volume.

5)  Eventually, access every host server and remove mpath device manually 
(multipath -f )

SAN is a DELL Compellent SC040
Cheers
AG

Hello again,

Just to provide an update for future reference, I’ve been unable to sort this 
problem out.
However, Ovirt4 does not show this failure.

Handling of unmapped luns was fixed in 3.6.

The best way is to upgrade to 3.6, and then upgrade to 4, and I think this is 
also
the only supported upgrade path.


My current approach to move VMs from one installation to another is:
1)Shutdown VM in ovirt3.
2)Maintenance VM storage - do you mean the storage server?
3)Clone VM storage at LUN level
4)Import cloned storage in ovirt4
5)Import VM in ovirt4
If everything is ok:

You must put the storage domain to maintenance here.

Since we don't support yet removal of pv from a storage domain, you cannot
remove a lun from a storage, you must remove the entire storage domain.

6a)  detach + remove original VM storage in ovirt3
7a)  remove mappings for original VM storage LUN in ovirt3; this imply 
cluster instability (sanlock crash on hosts);
8a)  recover cluster; this implies shutting down host (and its VM) one 
by one
9a)  delete unmapped original LUN from storage manager

When Sanlock freeze on host, the only solution found so far is to reboot it. 
This has to be done on all host experiencing this problem (which basically 
means: all hosts in the cluster)

If sanlock freezed it means that you unmapped a lun that was used by sanlock.
This is not supported.

Hello people,

something’s not right in my ovirt infrastructure.
I currently have two different ovirt installation:
Ovirt3: 7 hosts linked to Compellent iscsi storage running ovirt 3.5.6
Ovirt4: 4 hosts linked to (same) Compellent iscsi storage running ovirt 4.0.4

I’m currently moving my guests from ovirt3 to ovirt4.
Since iscsi storage is linked to both installations, my high level approach is:

1)  Shutdown VM in ovirt3.

2)  Maintenance + detach + remove VM storage in ovirt3

3)  Change LUN mapping via iscsi storage manager from ovirt3 to ovirt4

4)  Import storage in ovirt4

5)  Import VM in ovirt4

6)  Run and cheers with high grade liquor. GOTO step 1 for different VM.

Now, as soon as I perform step 3 (remove mappings from LUN), ovirt3 goes crazy 
and eventually forces me to reboot all hosts one by one.
I tried different low level approaches to unmap LUN mpath’ed from hosts with 
inconsistent results.
A notable error log extract is:

[ovirt-users] Ovirt 4.04 unable to umount LUNs on hosts

[Andrea Ghelardi]

Hello ovirt gurus,
I'd like to bother you with a long lasting issue I face.
My (new) test setup (not production one) is running ovirt 4.04 hosted engine on 
a Dell R510 server connected to SAN Compellent SC040 via iscsi.
All systems installed from scratch following guidelines.
Ovirt hosted engine installed using ovirt-appliance.
Everything is working "fine".
BUT
We are unable to perform a clear LUN removal.
We can perform all actions from web interface (storage add, maintenance, 
detach, delete) with no error.
However, underlying device remains mapped to server. As a result, we are unable 
to unmap the LUN otherwise multipath fails, server fails, ovirt fails etc.

Steps to reproduce:

1)  Create LUN on SAN, map it to server -> OK

2)  Log in ovirt web interface, add a new storage targeting LUN -> OK

3)  Create disk, create VM setup VM, (optional) -> OK

4)  Shutdown VM -> OK

5)  Ovirt: Put storage in maintenance -> OK

6)  Ovirt: Detach storage -> OK

7)  Ovirt: Delete storage -> OK

Expected result:
Ovirt unmaps and remove device from multipath so that it can be destroyed at 
SAN storage level.
It should be possible to perform this action even when host is not in 
maintenance.

Current result: volume remain locked in multipath (map in use).
Trying vgchange -a n  and then multipath -f  removes device, 
but then it is automatically re-added after a while (???)

Please note: this is the same behavior we always faced also with our ovirt 
production environment.
Details attached. Volume to be removed: LUN 64

Any ideas?
Thanks
AG

Re: [ovirt-users] ovirt 3.5.6: ERROR: duplicate key value violates unique constraint "pk_images" during import

[Andrea Ghelardi]

Ciao Sandro,
I understand your curiosity, and as said this is our production environment and 
we do not have a test one to check upgrades before going live.
Coupled with the fact that system performed reasonably well until now and that 
we have a long time (bad) habit of “not trying to fix what’s not broken”, we 
ended up in this situation.
I’m trying to fix this approach since the last few months but changing company 
habits is a rather slow process.

Cheers
AG

No, I'm just asking because 3.5.6 has been released on 2015-12-01. You haven't 
updated to 3.6 in 3.6 life cycle and now even 3.6 is gone to end of life adn 
we're already at 3rd maintenace release for 4.0.
You're missing something like 2000 bug fixes / updates including security 
fixes, urgent and high severity fixes and lot of new features (that you may or 
may not need, but still...)
So I'm just curious about why you didn't upgrade. If something blocked the 
upgrade on a test environment or an upgrade on a new version showed regressions 
or degraded performance or maybe just a matter of "don't change what works fine"

It would be great to recover the entire VM, but I’m more interested in disks

Hi Andrea,

IIUIC the problem occurs during import VM from external domain. I can see two 
options to save data on disks:
* Export storage domain can be detached and removed from engine. Install new 
separate engine and try to import VMs into new engine.
* Alternative is to use virt-viewer to create a vm and directly attach images 
form export domain to the vm. The images have standard qcow2 format.

Does any body have any idea why this is happening?

Hi Fernando,

The red hat bug id would have been appreciated, anyway this is the
resolution proposed

Resolution

Add the no_root_squash option to the NFS export (RHEV export domain -
/etc/exports):
/data/export*(rw,no_root_squash)

Re: [ovirt-users] upgrade path from Ovirt 3.5x to 3.6x

[Andrea Ghelardi]

Thanks Michal,

Your reply somehow answer to my question, but I still have some bits of
fuzziness

Hosted engine VM upgrade itself is almost clear (maintenance, db backup,
reformat, reinstall, db import).

However:

1.   Inter-cluster migration is somehow unsupported. Should we worried
about moving VM from EL6 cluster to EL7? You know... different vdsm etc
is ovirt migration feature atomic and reversible (if something goes wrong
during the process)?

2.   More important: the only Ovirt version that supports both EL6.6
and EL7.1 is 3.53. my real question is: what happen as soon as I finish
upgrade of my ovirt to version 3.54 (or 3.55) *while running HOSTS on EL6.6*
?



I mean, there will be a point in time when a version mismatch/overlap will
be unavoidable.

For example: how people should correctly jump from version 3.53 (EL6.6) to
3.54 (EL6.7)?



Ovirt team should support at least one or two previous version to support
overlaps...



Thanks

nono, the upgrade is live and all your VMs can keep humming. But there are
manual steps involved:



Simone can probably update about Hosted Engine which would be somewhat
special, but at least for regular VMs you can currently use:

1) create a new cluster with same settings as your existing cluster

2) remove one host from the old cluster (the one to be upgraded/reinstalled
to EL7). While moving the host to maintenance your VMs will be migrated to
other EL6 hosts in that cluster (make sure you have enough capacity to do
that beforehand, of course:)

3) upgrade/reinstall the host with EL7. If youdon't have anything custom on
the host reinstallation might be the best option

4) add it to the new cluster, installing/deploying it via UI, then it
should come up - this is your EL7-based cluster now

5) manually migrate (Migrate To button) some of your VMs from the old
cluster to the new one (there's an advanced section in the dialog, allowing
you cross-cluster migrations

6) repeat until all your hosts and VMs are on EL7-based cluster, then you
can decommission it, and perhaps rename the cluster back to its original
name

[ovirt-users] upgrade path from Ovirt 3.5x to 3.6x

[Andrea Ghelardi]

Hallo,

I needed a quick confirmation on this subject.



Our environment is Ovirt 3.511 (yes, I’ll upgrade soon, I know) running on
a Centos 6.6 hosted engine VM on a cluster of Centos 6.6 physical servers.



Since Ovirt 3.6x will be compatible with Centos 7 hypervisor only, how I’m
supposed to upgrade hosted engine, VM and HOSTs?



i.e. readme tells us the well known procedure (put hosted eng in
maintenance, upgrade, etc) but I will eventually end in a scenario where my
hosted engine 3.6 will run on centos 7 VM running (on) a lot of centos 6.6
servers...



Please tell me I have not to create a totally different datacenter and
export -> import all VMs...



Thank you!

Re: [ovirt-users] oVirt Instability with Dell Compellent via iSCSI/Multipath

[Andrea Ghelardi]

Hi Chris,
I have an Ovirt + Dell Compellent similar to yours (previous model, not
SC8000) and sometimes I faced issues similar to yours.
>From my experience I can advise you to
A) check links between SAN and servers, all paths, all configuration,
cabling. Everything should be setup correctly (all redundant paths green,
server mappings etc) BEFORE installing ovirt. We had a running KVM
environment before "upgrading" it to ovirt 3.5.1
B) Also check fencing is working both manually and automatically
(connections to iDRAC etc). This is a kind of pre-requisite to have HA
working.
C) I also noticed that when something is not going well on one of the
shared storage, this brings down the whole cluster (VM run, but a lot of
headaches being). First of all note that ovirt tries to stabilize the
situation itself for as long as ~15 minutes or more. It is slow in
re-fencing etc. Sometimes it enters in a loop and you have to locate the
problematic storage. You want to check the multipath on every server is
working correctly.

If you are having problems with just two nodes, I guess something is not
really ok at configuration level. I have 2 clusters, 12 hosts and several
(lots) of shared storage working and usually when something goes wrong is
because of an human error (like when I deleted the LUN on the SAN before
destroying the storage on the ovirt interface).

On the hand, I have the overall impression that the system is not
forgiving at all and that it is far from being rock solid.

Re: [ovirt-users] missing disk after storage domain expansion [SOLVED]

[Andrea Ghelardi]

Thanks for all your information.
I created a linux script as per details below.
Attached to this email (some info purged)

Gentlemen, we have a disk now!

I'm marking the post as solved ... even though we do not know where the disk
gone in these weeks yet.
Probably unexpected vacation @Cuba? This disk won't reclaim expenses though

I will create a test VM and perform some tests in the future with the
expansion feature
Thank you for all your support

I'd suggest to try a command line client, as it is easier to share the
results and check what is going wrong. You can use the "curl" command, for
example. Assuming that you already know the identifiers of the storage
domain and of the disk to register it should be something like this:

---8<---
#!/bin/sh -ex

url="https://yourengine/ovirt-engine/api";
user="your user"
password="your password"
storage_domain_id="the storage domain id"
disk_id="the disk id"

curl \
--verbose \
--insecure \
--user "${user}:${password}" \
--request POST \
--header "Content-Type: application/xml" \ --header "Accept:
application/xml" \ --data "

" \
"${url}/storagedomains/${storage_domain_id}/disks;unregistered"

Re: [ovirt-users] missing disk after storage domain expansion

[Andrea Ghelardi]

Hi Maor,

1) disk creation: ok
2) no free space at the moment of creation: this is very strange! Are you
sure? I assure you the disk was working, exported to VM which formatted and
wrote data on it
3) no disk removal mention: this is the very issue I'm facing. In fact disk
disappeared with no notification, no logs, nothing. I'm forwarding you full
set of engine.log separately. If you need vdsm.logs just tell me from which
server you need it as I have several cluster.
4) I have not yet tried to register using the procedure you provided me
earlier. I'll try tomorrow.

Hi Andrea,

I guessed I missed those logs, I found it now, thanks.

I do see the disk creation in the log from 20150501, I can also see that the
Storage Domain hertz-dstore2 has 0 GB of free space at the moment of
creation:
2015-05-01 03:30:05,801 ERROR
[org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector]
(DefaultQuartzScheduler_Worker-92) Correlation ID: null, Call Stack: null,
Custom Event ID: -1, Message: Critical, Low disk space. hertz-dstore2 domain
has 0 GB of free space

though, I don't see any indication of the removed disks from the engine.
I have also noticed a gap from the first log which finished at 2015-05-01
03:30:05 and the other log which starts at 2015-05-04 03:22:19,879.

Did you try to register the disk as described in the wiki?

Maor

Hi Andrea,

The OVF_STORE disks are disks which mainly being used internally in the
engine to store VMs' and Templates' OVFs, you can disregard them for now.

The behavior you mentioned, that suddenly the disk has disappeared from the
setup, sounds very weird and I would like to investigate this a bit more.
if you can please add the engine and vdsm logs, I can know what made the
disk get removed from the setup, at the first place.
Could it be that some one accessed the data base by any chance?

Regarding the disk registration, basically it should not create any problems
unless, if your disk was deleted manually form the DB, and there are still
leftovers related to the disk in some of the tables.
Once the disk is registered to the setup, you can try to attach it to the
VM, and try to run it.

Maor

Re: [ovirt-users] missing disk after storage domain expansion

[Andrea Ghelardi]

After querying the hosted engine with the suggested command
https://pisa-ion-ovirtm-01/ovirt-engine/api/storagedomains/7a48fe46-2112-40a4-814f-24d74c760b2d/disks;unregistered

Indeed shows  a (unregistered?) disk







hertz_disk5
disk for SYBASE installation, on SAN shared
storage

ok

I'm waiting for any comments on the two OVF disk or any advice before
proceeding with the registering command
(test in production environment hm)

Thank you for your reply!
I'm unsure if the disk contained any snapshots. I do not think so.
Is the register action a safe one to do in production system? I wouldn't
mess any of my existing running servers.

Here the relevant logs from the date
./engine.log-20150501.gz:2015-04-29 16:10:40,868  : disk creation
("hertz_disk5" newImageId = 4ab070c0-fb16-452d-8521-4ff0b004aef3)
./engine.log-20150512.gz:2015-05-04 17:22:42,691  : last  occurrence of the
imageid

Please note from
./engine.log-20150512.gz  2015-05-11 12:07:16,719 : creation of two disk OVF
store (??) on the same storage domain 7a48fe46-2112-40a4-814f-24d74c760b2d
right after the volume expansion

In the instructions.txt  what I did to enlarge the volume (and lose the
disk) (the guides is informational only, I followed the steps on a different
server)

Hi Andrea,

First of all, the issue sounds quite severe, can u please attach the engine
logs so we can try to figure out how that happened.
second, does this disk contained any snapshots?
 If not, can you try to register it back (see
http://www.ovirt.org/Features/ImportStorageDomain#Register_an_unregistered_disk)

Re: [ovirt-users] Problems with ISCSI storagedomain

[Andrea Ghelardi]

Hi Luciano,
I suggest you to check log files which usually provide a goof indication of
what is going on usually
You want to check the engine logs (ssh into your hosted engine, then
/var/log/ovirt-engine) and vdsm logs on your hosts (/var/log/vdsm/vdsm.log)
You want also to check if you multipath is updated and ok (multipath -ll or
lsscsi)

Cheers

Subject: [ovirt-users] Problems with ISCSI storagedomain

Hello everyone!

I'm running oVirt 3.5, and recently had an issue with a split brain
situation in the hosted engine's image. After solving that, I got the engine
up an running, but something went wrong with my main storage.
I have a datacenter with main storage being ISCSI, called vms-main-storage.
This storagedomain is marked as inactive. The only action I can attemp to do
to it is activate it. But it won't. It just fails and no reason is given in
the web ui. I also tried activating it through the cli, and result is status
400, reason bad request, detail internal engine error. Strange thing is that
VM's are still running with their images in this storage and they are
running with no problem at all!
How can I have this storagedomain again in a healthy state???
Thanks!

Ok, so,

After _*a lot*_ of unsuccessful approach, I finally connected to postegre
DB directly.

Browsing the tables I found “unregistered_ovf_of_entities” where there is a
reference of the missing disk

Hi gentlemen,



I recently found an error on 1 of my storages: it was complaining about no
free space but the VM was running and disk operational.

Since I needed to perform some maintenance on the VM, I shut it down and at
restart VM couldn’t boot up properly.

Checked VM via console and a disk was missing. Edited fstab (luckily this
disk was not root but heck! It had a Sybase DB on it!) and restarted VM
this time ok.



Since the disk resides on the dstore with no space, I expanded the iSCSI
LUN, then refreshed multipath on hosts, then resized PVs and now ovirt is
showing the correct size (logs do not complain anymore on no free space).



BUUUT



Now disk is missing. It is not shown anymore on Disks tab nor anywhere else.

Problem is that storage shows 214GB occupancy (size of the missing disk) so
data is there but cannot find it anymore.



Logs show original disk creation, errors from the lack of space, refresh of
the storage size and then no more references on the disk.



What can I do to find those missing ~210GBs?

Re: [ovirt-users] Local Storage

[Andrea Ghelardi]

Hi Scott,
Thank you for your reply. I indeed scratched my face on the wall due to
this approach.
However, we are taking care not to mix iscsi shared and local shared LUNs
on the same datastore.
I understand this is unsupported and discouraged as well but not so
tragic?

Cheers
AG

Hello,

The major point that needs to be stressed again and again on this mailing
list is:

At this time, it is best practice to _NEVER_ combine the shared storage
onto the cluster hosts.

There are MANY many MANY posts from people with down oVirt environments
because they combined their shared storage on their hosted cluster
(especially gluster storage).

They do not fully understand the horrible consequences that will happen
when 1) a host cluster node gets fenced, 2) their gluster cluster becomes
split-brained because they failed to understand gluster and quorums, or 3)
a network connectivity issue of some sort breaks the storage cluster on
one (or many) node(s) and then the issue cascades to the other systems
bringing the entire shared storage + clustered hosts to a grinding halt.

As a consequence, this mailing list gets flooded with pleas for help from
a crashed oVirt setup that did not follow best practices.

In my opinion, those who combine shared-storage onto the host-nodes need
to pull the plug on one of their hosts, and then work through the numerous
issues that will result in their hyper-converged configuration.

If the SysAdmin does not have that experience of working through all of
the problems that result from hyper-converging shared storage on the host
nodes, then they certainly need to avoid combing shared storage on the
host nodes.

Good Luck!

Re: [ovirt-users] Local Storage

[Andrea Ghelardi]

It is true that you cannot mix local and shared storage types.

However, it is actually possible tricking local storage to be presented as
a shared iscsi volume and then passed to ovirt

There are drawbacks but we are actively using this solution.

Host is part of cluster which is part of DC.

DC can be shared or local only, can't be both.

[ovirt-users] missing disk after storage domain expansion

[Andrea Ghelardi]

Hi gentlemen,



I recently found an error on 1 of my storages: it was complaining about no
free space but the VM was running and disk operational.

Since I needed to perform some maintenance on the VM, I shut it down and at
restart VM couldn’t boot up properly.

Checked VM via console and a disk was missing. Edited fstab (luckily this
disk was not root but heck! It had a Sybase DB on it!) and restarted VM
this time ok.



Since the disk resides on the dstore with no space, I expanded the iSCSI
LUN, then refreshed multipath on hosts, then resized PVs and now ovirt is
showing the correct size (logs do not complain anymore on no free space).



BUUUT



Now disk is missing. It is not shown anymore on Disks tab nor anywhere else.

Problem is that storage shows 214GB occupancy (size of the missing disk) so
data is there but cannot find it anymore.



Logs show original disk creation, errors from the lack of space, refresh of
the storage size and then no more references on the disk.



What can I do to find those missing ~210GBs?

[ovirt-users] Datacenter unresponsive: recovery procedure?

[Andrea Ghelardi]

(sorry: resending as I wasn’t part of the list, yet)



hi,

this is my first post so hallo all and thank you for reading.

I have an issue with my production Ovirt environment (3.5.1.1-1.el6).



My system consists of several datancers.

2 of them are connected to an iSCSI SAN and they were working fine.

Until the moment I had the bad idea of deleting a SAN volume from the SAN
manager before deleting the associated storage on Ovirt. From that moment,
the DC where this storage was mounted became not responsive: it cannot
attach the master storage (or any other).

I tried to

1) manually destroy the offending storage (select -> destroy) but still
cannot recover the situation.

2) right click on master storage and activate it

3) re-initialize the datacenter using a NFS storage from the working sister
DC.



All Hosts are still running even though their status is "unknown".

All VM are still running even though their status is "not responding".



I half resolved the issue by manually restarting the host where the
datastore was originally mounted. This cleared the orphaned multipath.

However, the SPM does not come up still.

This is an extract of the log

I’m thinking about

*Put the hosted engine host into Maintenance*

*Shutdown Ovirt Manager*

*Rebooted SPM server*

*Restarted Ovirt Manager*

*Took hosted engine host out of Maintenance*





any help or clue is highly welcomed with cheers and beers
