They should not be rebooted automatically, but you might need to do
this yourself, see below.

Please provide more details about your backup/restore flow.
What died (storage? hosts? data?), what are you going to restore,
how, etc.

Which hosts are hosted-engine hosts. Do they have running VMs.

We are working on updating the documentation, but it will take some time.

For now, you should assume that the safest way is to pass during restore,
to engine-backup, '--he-remove-storage-vm' and '--he-remove-hosts'. This
will remove from the engine all the hosted-engine hosts and storage. So
when you add the hosts back, you'll have to somehow power off the VMs
there - the engine will refuse to add them with running VMs. If you do
not want to use these options, you should plan carefully and test.

Re: [ovirt-users] how to redo oVirt cluster?

[Luca 'remix_tj' Lorenzetto]

Hello Rudi,

I think that uninstalling ovirt-engine and removing vdsm from hosts should
be enough. Pay attention to cleaning up engine db which contains all the
engine data.

[ovirt-users] how to redo oVirt cluster?

[Rudi Ahlers]

Hi,

I have setup an oVirt cluster and did some tests. But how do I redo
everything, without reinstalling CentOS as well?
Would it be as simple as uninstalling all the ovirt? Or do I need to
manually delete some config files and other traces off the install as well?

Hi again,

OK, tried to stop all the vms, except the engine, set engine-config -s 
LibgfApiSupported=true (for 4.2 only) and restarted the engine.

When I tried restarting the VMs they are still not using gfapi, so it does 
not seem to help.

The compatibility flag is correctly showing gfapi should be enabled with

LibgfApiSupported: false version: 3.6

Any clue of what I'm still missing?

ok. Thanks for clarifying the concept.
But from the inline help of taskcleaner.sh it is not so clear to me which
option makes it display vs remove...
Perhaps without options it only display? or with "-T" it first displays
asking if I want to remove "all comands that have running tasks"?
How can I only display?

How can I check this?
Is still valid this command I found on a previous (around 2014) thread and
executed on the SPM (as shown in web admin portal) host right now?

[root@ov300 vdsm]# vdsClient -s 0 getAllTasksStatuses
{'status': {'message': 'OK', 'code': 0}, 'allTasksStatus': {}}

[root@ov300 vdsm]#

Does it mean no task?

[ovirt-users] Issue with hosted engine restore.

[Krzysztof Wajda]

Hello,

I have to restore Hosted Engine on another host (completely new hardware).
Based on this
https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restoring_an_EL-Based_Self-Hosted_Environment/
is not clear for me if vm's will be rebooted during synchronization hosts
with engine ?

I have 5 hosts + 1 completely fresh. On host1 I have HE and there is no
vm's on other 4 (host1-4) there are around 400 vm which can't be rebooted.
Host5 for restore HE.

[ovirt-users] Snapshot or not?

[Demeter Tibor]

Dear Users, 

I have a disk of a vm, that is have a snapshot. It is very interesting, because 
there are two other disk of that VM, but there are no snapshots of them. 
I found this while I've try to migrate a storage-domain between two datacenter. 
Because, I didn't import that vm from the storage domain, I did an another 
similar VM with exactly same sized thin-provisioned disks. I have renamed, 
copied to here my originals. 

The VM started successfully, but the disk that contain a snapshot did not 
recognized by the os. I can see the whole disk as raw. (disk id, format in 
ovirt, filenames of images, etc) . I think ovirt don't know that is a 
snapshotted image and use as raw. Is it possible? 
I don't see any snapshot in snapshots. Also I have try to list snapshots with 
qemu-img info and qemu-img snapshot -l , but it does not see any snapshots in 
the image. 

Really, I don't know how is possible this.

qemu-img snapshot -l 5974fd33-af4c-4e3b-aadb-bece6054eb6b 

(nothing) 

Because it is a very big (13 TB) disk I can't migrate to an another image, 
because I don't have enough free space. So I just would like to use it in ovirt 
like in the past. 

I have a very old ovirt (3.5) 

How can I use this disk? 

Thanks in advance,

Tibor

Re: [ovirt-users] how to clean stuck task

[Fred Rolland]

For cleaning these "Tasks" entries (which are actually Jobs in the DB), you
will need to use taskcleaner.sh.
The unlock_entity.sh is for removing locks on entities.

Before running the task cleaner, you need to be sure you actually don't
have any tasks running in the SPM.

Regarding the snapshot creation on 'apex", can you provide the logs around
the time of the operation?

I have just verified that if I run a new task (in my case has been the
removal of the snaptest VM), suddenly I see from 0 to 3 tasks, with the
deletion task completing with success, while the 2 stale tasks appearing
again in the task pane where they disappeared

I'd prefer to avoid direct manage of the rdbms...

As it happened on Friday, after running again the command

PGPASSWORD=... /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t
all -u engine

now the gui after some time shows no active task

but the vm still shows as locked and in the event pane I only have the
message
Snapshot '13-11-2017-16-30-Danilo' creation for VM 'apex' was initiated by
user1@internal-authz.
but no message about its correct completion

This is my disks' subtab situation for the vm, where it seems all ok:
https://drive.google.com/file/d/1tF3VdA8gzMVvtn2x4HTKOmltRmUR7cTG/view?usp=sharing

And this the snapshots' subtab where it seems all ok:

But the VM has the lock symbol in side of itself.

Re: [ovirt-users] how to clean stuck task

[Wesley Stewart]

Is the VM showing as locked?  You could try to manually unlocking it.  I
did this in a test environment a while back with some success after a vm
was stuck in a "locked" state.  Of course the gui and engine should handle
most of this for you, manually mucking around the internal DB can cause
some pretty serious issues if you are not careful...

sudo su postgres

psql -d engine -U postgres

SELECT vm_guid, vm_name FROM vm_static WHERE vm_name='*VM_Name_Here*';
This should return a string such as: "0ec20854-e1ca-4e49-be87-a6cd36d40c18"

Reset the lock:
update vm_dynamic SET status=0 where vm_guid='
0ec20854-e1ca-4e49-be87-a6cd36d40c18';

Re: [ovirt-users] how to clean stuck task

[Gianluca Cecchi]

Hello,

it seems the same lock (with the same date) has come again in the list of
tasks.
Now I have two things in "supposed running" tasks:
- the "Restoring VM Snapshot Active VM before the preview of VM snaptest"
of 8/11
- the "Creating VM Snapshot 13-11-2017-16-30-Danilo for VM apex"  (now
running since half an hour for a vm that has only one 90Gb disk on SAN FC
storage domain)

It was not me to run the "create snapshot" command today, so I'm not sure
if it was the snapshot creation job responsible of letting come out again
the former hung task... or if it was already there before...
Any further hint?
How can I manually verify the status of the snapshot creation task?

Gianluca

When using files, sanlock always does 512 byte i/o.  This can be a problem
when there are 4k disks used under NFS.  On disks, sanlock detects the
sector size (with libblkid) and uses 512/4k accordingly.

If vdsm knows when to use 4k i/o over files, I can add a sanlock flag that
vdsm can use to create 4k sanlock leases.

Re: [ovirt-users] Host in kdumping state

Sorry for not following-up...well as strange as it sounds, after replacing
the faulty HW while keeping the same old disks (basically putting the disks
in a new identical server) the kdumping error disappeared and the host is
back working as usual.
Maybe "kdumping" is displayed after a kernel panic reboot?

[ovirt-users] oVirt 4.1 - "Create virtual disk - thin provisioning" makes RAW by default not QCOW2

[andreil1]

Hi,

Just got test setup of oVirt 4.1 running. 
Seem to be really brilliant piece of software.


1) Defined local storage domain.

Create virtual disk - thin provisioning makes RAW images by default instead of 
QCOW2.
It preallocated all space in advance.
I looked inside META file in the same folder as disk image - it is marked as 
RAW.

May be its converted to RAW because I formatted it as 3 partitions: SWAP + Boot 
Ext4 + Root Ext4 ?
Should I use single Ext4 partition per virtual disk image to keep it QCOW2 ?

Is there any way to change this behaviour, or convert RAW into QCOW2 within 
oVirt? Certainly I can do it with QEMU, but image become unregistered, or may 
be some functionality become broken.


2) SWAP partition - is it better to create small 1GB SWAP as RAM disk or use 
4GB partition on virtual RAW disk, or I’m wrong here ?


Thanks in advance.

Re: [ovirt-users] recommendations for best performance and reliability

Just curious. Would Gluster with a JBOD configuration make sense in this

In general, does a Gluster JBOD configuration make sense as a backend
for oVirt?

Re: [ovirt-users] recommendations for best performance and reliability

[FERNANDO FREDIANI]

Hello Rudi

If you have a 4th server it may work,but I am not knowledgeable about 
Gluster's GEOreplication. Perhaps someone else can advise.


With regards RAID 5 for 4 disks this is intended for capacity and as 
mentioned 4 disks is the maximum I would use for RAID5. As you have SSDs 
and intend to use a caching technique like bcache ou dm-cache this 
should cover the performance hit of RAID 5 write.
If you consider using RAID 6 in only 4 disks you are much better of 
using RAID 10 then as you will have double write performance and same 
capacity. I normally use RAID 10 or in ZFS configurations (not this 
case) multiple vdevs of RAID6.


For RAID in Linux I have been using mdraid. I know LVM does some Raid 
but I personally never done myself so can't advise.


Regards.
Fernando

Hi Fernando,

Thanx.

I meant to say, the 4th server will be in another office. It's about 
3Km away and I was thinking of using Gluster's GEOreplication for this 
purpose.


I am not a fond user of RAID5 at all. But this raises the question: 
does RAID add any unnecessary overhead? I would rather run RAID 6 or 
RAI10.
And then, if RAID is the preferred way (over LVM?), as I don't have 
dedicated hardware RAID cards, would mdraid add any benefit?

Nice specs.

I wouldn't use GlusterFS for this setup with the third server in a
different location. Just have this server as an Standalone and
replicate the VMs there. You won't have real time replication, but
much less hassle and probably to have constant failures, specially
knowing you have a wireless link.

For the SSDs I have been using bcache with success. Relatively
simple to setup and pretty good performance.

For your specs as you have 4 mechanical disks I would recommend
you to have a RAID 5 between them (4 disks is my limit for RAID 5)
and a RAID 0 made of SSDs for the bcache device. If the RAID 0
fails for any reason it will fall back directly to the mechanical
disks and you can do maintenance on the Node doing live migration
in order to replace the failed disks.

However as you have you have 2 remaining server to create your
cluster you may need to consider GlusterFS on the top of this RAID
to have the replication and Highavaibility.

Hope it helps.

We have the following hardware setup:

3x Supermicro server with following features per server:
128GB RAM
4x 8TB SATA HDD
2x SSD drives (intel_ssdsc2ba400g4 - 400GB DC S3710)
2x 12 core CPU (Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz

2x 10GB Cisco switches (to isolate storage network from LAN)

One of the servers will be in another office, with a 600Mb
wireless link for Disaster Recovery.

What is recommended for the best setup in terms of redundancy and
speed?

I am guessing GlusterFS with a Distributed Striped Replicated
Volume across 3 of the servers.

For added performance I want to use the SSD drives, perhaps with
dm-cache?

Should I combine the 4x HDD's using LVM on each host node?
What about RAID 6?



Virtual Machines will then reside on the oVirt Cluster and any
one of the 3 host nodes can fail, or any single HDD can fail and
all should still work, right/?

Re: [ovirt-users] recommendations for best performance and reliability

[FERNANDO FREDIANI]

Helli Rudi

Nice specs.

I wouldn't use GlusterFS for this setup with the third server in a 
different location. Just have this server as an Standalone and replicate 
the VMs there. You won't have real time replication, but much less 
hassle and probably to have constant failures, specially knowing you 
have a wireless link.


For the SSDs I have been using bcache with success. Relatively simple to 
setup and pretty good performance.


For your specs as you have 4 mechanical disks I would recommend you to 
have a RAID 5 between them (4 disks is my limit for RAID 5) and a RAID 0 
made of SSDs for the bcache device. If the RAID 0 fails for any reason 
it will fall back directly to the mechanical disks and you can do 
maintenance on the Node doing live migration in order to replace the 
failed disks.


However as you have you have 2 remaining server to create your cluster 
you may need to consider GlusterFS on the top of this RAID to have the 
replication and Highavaibility.


Hope it helps.

We have the following hardware setup:

3x Supermicro server with following features per server:
128GB RAM
4x 8TB SATA HDD
2x SSD drives (intel_ssdsc2ba400g4 - 400GB DC S3710)
2x 12 core CPU (Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz
Quad port 10Gbe Inter NIC
2x 10GB Cisco switches (to isolate storage network from LAN)

One of the servers will be in another office, with a 600Mb wireless 
link for Disaster Recovery.


What is recommended for the best setup in terms of redundancy and speed?

I am guessing GlusterFS with a Distributed Striped Replicated Volume 
across 3 of the servers.


For added performance I want to use the SSD drives, perhaps with dm-cache?

Should I combine the 4x HDD's using LVM on each host node?
What about RAID 6?



Virtual Machines will then reside on the oVirt Cluster and any one of 
the 3 host nodes can fail, or any single HDD can fail and all should 
still work, right/?

[ovirt-users] oVirt 4.1.9 will be the last 4.1 release

[Sandro Bonazzola]

Hi,
we are now targeting oVirt 4.2.0 GA around December 12th and oVirt 4.1.8
around December 5th.
Against tradition that would have set 4.1.8 as last 4.1 release, this round
we'll release also oVIrt 4.1.9 being it already in development just before
4.2.0 GA.

We suggest to be prepared to upgrade to 4.2 since 4.1 won't receive any
further update after 4.1.9 release.

Hi,
just a small addition:
we can deploy hosted-engine choosing vnc or spice as the graphical console
protocol so you have to fix the remote viewer command according to what you
are using.
And the tcp post is not always 5900 but it depends on the VMs starting
order.

To get the actual VNC port number you could use:
. /etc/ovirt-hosted-engine/hosted-engine.conf
vdsm-client VM getInfo vmID=$vmid | jq -r '.devices[] | select(.device |
contains("vnc")).port'

An alternative is to use the serial console with:
hosted-engine --console

Re: [ovirt-users] Hosted Engine is down

[Martin Sivak]

Hi,

Following my answer, this is the bug you opened to track this issue right?

https://bugzilla.redhat.com/show_bug.cgi?id=1511788

You said in comment #2 of that bug that all is well now. Should we
close the bug then?

Best regards

[ovirt-users] recommendations for best performance and reliability

Re: [ovirt-users] Installation of oVirt 4.1, Gluster Storage and Hosted Engine

[Open tech]

Hi All,
   I am new to Ovirt. I am hitting the exact same error while trying a new
install in a nested virtualization setup on esxi 6.5.
I am following this tutorial as well. Have three nodes on esxi with dual
networks & passwordless ssh enabled.
https://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4.1-and-gluster-storage/

Node install goes through without issue. Run into this error when i hit
deploy.

**
fatal: [ovirt3]: FAILED! => {"failed": true, "msg": "The conditional check
'result.rc != 0' failed. The error was: error while evaluating conditional

@Simone Marchioni were you able to find a solution ???.

Re: [ovirt-users] Hosted Engine is down

[Kasturi Narra]

Hi Logan,

When i look at the hosted-engine --vm-status i see that vm is up but it
is health is bad. Can you try connecting to the vm using remote-viewer
using the command below ?

remote-viewer vnc://ovirttest1.wolfram.com:5900

Thanks
kasturi
