Vdsm scans all LUNs to discover oVirt volumes, so it will be effected by
multipath
configuration applied only for direct LUNs.

Increasing no_path_retry for any LUN will increase the chance to delay some
vdsm flows accessing LUNs (e.g. updating lvm cache, scsi rescan, listing
devices).
But the delay happens once when the multipath device loose all paths. The
benefit
is smaller chance that a VM will pause or restart because of short outage.

Ah, Ok. That would make sense. I had checked the events via the UI and it
didn't show any pauses, but I had not checked the actual VDSM logs on the
hosts. Unfortunately my logs of for the period have rolled off. I had
noticed this behaviour during our first firmware upgrade on our SAN about a
month ago. Since VM leases allowed us to maintain HA I just put it in my
list of things to follow up on. Going forward I will make sure to double
check the VDSM logs to see what is happening in the background.

Would that increased delay cause any sort of issues for Ovirt (e.g.
thinking a node is offline/unresponsive) if set globally in multipath.conf?
Since a Direct LUN doesn't use LVM, would this even be a consideration if
the increased delay was limited to the Direct LUN only?

[ovirt-users] Deleting master storage

2018-07-24 Thread

Hi,

Trying to build an ovirt system and i'm stuck with storage problem. I've
prepared iscsi storage and seems like my storage had some troubles and now
i could not get it online again. That is another story. I just want to
delete master storage domain on ovirt manager. Looks like this is not
allowed since there is no storage domain candidate to take master role.
Also i could not add another storage domain becouse that is not allowed
too. It says "can not add because there is no active storage domain" or
something similar.

Basically i'm stuck and don't know how to delete storage domain (master)
without tear down all of them.

The engine is the brain of your system, it's a kind of orchestrator that
starts different tasks on your hosts.
You need an engine for new tasks but existing tasks such as running a VM
should not be affected at all by the lack of an engine.

I fear that your issue is somewhere else.
what do you exactly mean with "Hosts in Cluster B crash "? are you sure
that your hosts in data center B are not consuming storage exposed by hosts
in data center A?

Hi Hari,
   are you sure you want to assign the superuser permission for all the 
discovered users?
What level are you applying it to as it means everyone can change or delete 
everything below that level.

We put users into a directory group and give permissions to the group as Ondra 
suggested, then we only need to add users to oVirt if we need to add 
permissions to individual users.

[ovirt-users] Re: Upgrade from 4.1 to 4.2 failing - SQL Issues

2018-07-24 Thread Simone Tiraboschi

Hi,
it seams still pretty close to
https://bugzilla.redhat.com/show_bug.cgi?id=1528371 although that one was
on lc_collate and this on encoding.
Adding also Didi.

I just double check on a system of mine upgrade from 4.1 to 4.2 and
template1 is still on UTF8.

[root@enginevm tmp]# sudo -u postgres scl enable rh-postgresql95 -- psql
--list
 List of databases
 Name |Owner | Encoding |   Collate   |
Ctype|   Access privileges
--+--+--+-+-+---
 engine   | engine   | UTF8 | en_US.UTF-8 |
en_US.UTF-8 |
 ovirt_engine_history | ovirt_engine_history | UTF8 | en_US.UTF-8 |
en_US.UTF-8 |
 postgres | postgres | UTF8 | en_US.UTF-8 |
en_US.UTF-8 |
 template0| postgres | UTF8 | en_US.UTF-8 |
en_US.UTF-8 | =c/postgres  +
  |  |  | |
 | postgres=CTc/postgres
 template1| postgres | UTF8 | en_US.UTF-8 |
en_US.UTF-8 | postgres=CTc/postgres+
  |  |  | |
 | =c/postgres
(5 rows)


So the point is why the upgrade process is trying to force SQL_ASCII.
Can you please share your env variable values?

I guess the other VMs did get paused, but they were resumed

not "pause".

You can check vdsm log if the other vms did pause and resume. I'm not
sure engine UI reports all pause and resume events.

Right.

Can you file a bug for supporting this?

Vdsm does monitor multipath events for all LUNs, but they are used only
for reporting purposes, see:
https://ovirt.org/develop/release-management/features/storage/multipath-events/

We could use the events for resuming vms using the multipath devices that
became available. This functionality will be even more important in the
next version
since we plan to move to LUN per disk model.

I don't know about additional retry mechanism in the data-path for LVM

You can add a drop-in multipath configuration that will change
no_path_retry for specific device, or multiapth.

Increasing no_path_retry will cause larger delays when vdsm try to
access the LUNs via lvm commands, but the delay should be only on
the first access when a LUN is not available.

Here is an example drop-in file:

# cat /etc/multipath/conf.d/my.conf
devices {
device {
vendor "my-vendor"
product "my-product"
# based on 5 seconds monitor interval, queue I/O for
# 60 seconds when no path is available, before failing.
no_path_retry 12
}
}

multipaths {
multipath {
wwid "my-wwidr"
no_path_retry 12
}
}

See "man multipath.conf" for more info.

As per I know PostgreSQL does not convert encoding from one type to another

[ovirt-users] Uncaught exception occurred - NS_ERROR_FILE_CORRUPTED

2018-07-24 Thread Michael Seidel

Hi,

I am running oVirt in version 4.2 and just started getting this error
message upon login:

Uncaught exception occurred. Please try reloading the page. Details:
(NS_ERROR_FILE_CORRUPTED) :
Please have your administrator check the UI logs


The relevant content of the ui.log is given below (or, nicely formatted
at https://paste.ee/p/LUrbt).


I am able to access the js file directly using a browser so the file is
definitely not missing and is readable. However, the side-bar of the
ovirt webadmin is not showing (or more precisely: it loads and shows for
a split-second and then disappears).


The Web Console shows a similar error message as the one below,
referring to the same js file and in addition says:

Tue Jul 24 14:28:03 GMT+200 2018
com.gwtplatform.mvp.client.presenter.slots.LegacySlotConvertor
SEVERE: Warning: You're using an untyped slot!
Untyped slots are dangerous! Please upgrade your slots using
the Arcbee's easy upgrade tool at
https://arcbees.github.io/gwtp-slot-upgrader

The github-URL however is not working.

I also upgraded and rebooted the ovirt engine, but the error remains.


Do you have any suggestions what might cause this issue and how I can
fix it.

Best,
- Michael

This makes the vm depend on 3 storage domain - very fragile configuration.

I don't think we support this concept. When you start the vm, the disk must
exists.

If the disks are not needed when the vm starts, maybe you want to plug them
to the vm later by your application, only if the disks are available?

Even if you solved plugging the disks only when the storage is available,
you need
to handle errors while the disk is plugged to the vm.

If qemu fail to read or write to the disk, it must choose:
- pause the vm, so the I/O can be retried later when the vm is resumed
- stop the vm, maybe the operation will succeed on another host
- propagate the error the guest. This will like to make the file system
  in the guest read-only, which usually requires a restart of the vm to
recover.

The last option may work if the guest is using multipath, and multipath is
configured
to queue I/O forever on failures.

Vdsm supports different error policy per drive, but I don't see any UI for
setting this.

You can see the error_policy in the vm xml, available in vdsm log when
starting
a vm, or using virsh

virsh -r list

find your vm id or name, and then:

virsh -r dumpxml my-vm-name-or-id

Arik, do we have a way to control error policy per disk?

Another option is to mount the "optional" disks from within the vm,
so your application inside the vm have full control when there is trouble
to mount or access the optional disks.

[ovirt-users] Re: Raid configuration for single instance

2018-07-24 Thread Leo David

Hi,
I did the above changes on the server ( adding enterprise disks for storage
domains ),  and there are improvements. But.
I just had a vm getting into "VM paused due to I/O error"  :(  .
This vm has both disks as "thin-provisioning", and it runs as an OpenShift
node ( Centos 7).
Any chance that the problem could be because the disks are not
"pre-alocated" and the filesystem writes are to intensive ?
Getting a bit worried since this stack it's supposed to be seen as a
production system
Thank you very much !

[ovirt-users] Upgrade from 4.1 to 4.2 failing - SQL Issues

2018-07-24 Thread Sven Achtelik

Hi All,

I'm still struggling to upgrade from 4.1 to 4.2 and the root cause seems to be 
the SQL upgrade. I installed my 4.1.9 with the engine appliance image and 
restored a DB to it. My Upgrade to 4.2 is failing with the errors below:

Performing Consistency Checks
-
Checking cluster versions   ok
Checking database user is the install user  ok
Checking database connection settings   ok
Checking for prepared transactions  ok
Checking for reg* system OID user data typesok
Checking for contrib/isn with bigint-passing mismatch   ok
Checking for invalid "line" user columnsok
Creating dump of global objects ok
Creating dump of database schemas
  engine
  ovirt_engine_history
  postgres
  template1
ok

encodings for database "template1" do not match:  old "UTF8", new "SQL_ASCII"
Failure, exiting

I tried everything that could do and I also tried to find a solution on google 
to make this work. Could someone with DB knowhow please advise on the next 
steps to resolve this ? I really would like to upgrade somehow.

Thank you,
Sven

[ovirt-users] Re: How to keep VM running when a storage domain is offline

2018-07-24 Thread Johan Bernhardsson

You need replicated gluster storage for that. So that one part of the
storage can go down but two others still keep on running. And you need to
set the threshold so that a quorum of 2 is sufficient (if you have replica 3).

If the storage volume is offline. It would be the same as the same thing as
if you pulled the hard drive from a server.

So if ovirt wouldn't pause the virtual server then Linux would complain and
set it to read only.

Hello,

I am trying to understand how I can prevent a VM from being paused when one

The scenario:

A VM with 3 disks. OS disk on a highly available domain. And Two large
disks each on separate domains. (so a total of 3 domains).

The two large disks are mirrored using ZFS - but when one of the storage
domains goes down the VM pauses. Is is possible to configure the VM to not
pause when certain storage domains are unavailable? So instead of getting
Paused due to IO error the disk would just be missing until that domain was
brought back online?

Daniel, is ovirt-engine the best place for this bug, or we have a better
place?

Component: Documentation

In the description:
- describe the user visible issue
- describe the root cause (missing mount option?)
- describe the solution
- suggest where this solution should be documented in the manual

and others may benefit from the discussion.

Changing CD works when using another ISO file like Centos. The iso itself is 
good - I can read it on my own System - but anyhow I tried another download of 
the virtio-win-iso - with the same result.

I already found several threads around this Topic - e.g. "do not upload ISO

So I'd like to know how the upload to the ISO Domain is supposed to work if 
there's no "upload" button? Directly via SCP into the subfolders?
a) 
https://www.ovirt.org/documentation/quickstart/quickstart-guide/#uploading-iso-images
b) scp example.iso server:/…/…/…/…/images/----/

Did I miss some configuration or is the workflow in uploading ISO's

see above: floppy :-)

It appears you have permission issues on your storage.

I see you are using storageType='LOCALFS'

per https://www.ovirt.org/documentation/admin-guide/chap-Storage/

"Ensure that the directory has permissions allowing read/write access to the 
vdsm user (UID 36) and kvm group (GID 36)."

 

Can you verify that?

[ovirt-users] How to keep VM running when a storage domain is offline

2018-07-24 Thread Matthew B

Hello,

I am trying to understand how I can prevent a VM from being paused when one
of it's disks is unavailable due to a problem with the storage domain.

The scenario:

A VM with 3 disks. OS disk on a highly available domain. And Two large
disks each on separate domains. (so a total of 3 domains).

The two large disks are mirrored using ZFS - but when one of the storage
domains goes down the VM pauses. Is is possible to configure the VM to not
pause when certain storage domains are unavailable? So instead of getting
Paused due to IO error the disk would just be missing until that domain was
brought back online?

Thanks,
 -Matthew

[ovirt-users] Error when change CD

2018-07-24 Thread markus . schaufler

Hi!

I created an NFS ISO Domain but couldn't find any upload button. Because 
uploading ISO files on the Data Domain I went that comfortable way. I 
successfully started Installation of Windows Server 2016
until the virtio Drivers for the disk are needed. So I tried to Change CD but 
following error occured: 

"Error while executing Action Change CD: Drive Image file could not be found"

Changing CD works when using another ISO file like Centos. The iso itself is 
good - I can read it on my own System - but anyhow I tried another download of 
the virtio-win-iso - with the same result. 

I already found several threads around this Topic - e.g. "do not upload ISO 
files to data Domain" 
So I'd like to know how the upload to the ISO Domain is supposed to work if 
there's no "upload" button? Directly via SCP into the subfolders? 

Did I miss some configuration or is the workflow in uploading ISO's 
respectively in installing a Windows VM wrong?

Thanks for any help!

It's in state DOWN, but marked UP anyway.

A really DOWN interface is shown as (on another server, not an ovirt host):

That's it. I never ask it to be in such state.

[ovirt-users] Re: Sync LDAP users in Ovirt

Hi Ondra,

We are not using ovirtSDK, It is completely new to us.

*Is there an oVirt API *
   1) To discover all the users in LDAP using the provided domain and
namespace?
   2) Add all the discovered users in Ovirt?
   3) Assign the superuser permission for all the discovered users?

Thanks,
Hari

Something like this should work for you:

import ovirtsdk4.types as types

DOMAIN_NAME = 'internal-authz'

connection = sdk.Connection(...)

users_service = connection.system_service().users_service()

domains_service = connection.system_service().domains_service()
domain = next((domain for domain in domains_service.list() if 
domain.name == DOMAIN_NAME), None)

domain_service = domains_service.domain_service(domain.id)
users = domain_service.users_service().list()
for user in users:

eth2 seems to be in state DOWN, which seems to be reflected in
ifOperStatus.

Is the issue that ifAdminStatus is up for eth2 and eth3, but you want
it to be down?

[ovirt-users] interface up when not used

2018-07-24 Thread Fabrice Bacchella

To monitoring the network interfaces, I have a script that check if 
ifAdminStatus and ifOperStatus values matches in snmp.

But with oVirt it fails on a server with 4 physical interfaces, but only two 
connected, and return an error:

snmptable XXX IF-MIB::ifTable | less
SNMP table: IF-MIB::ifTable

 ifIndex ifDescr ifAdminStatus ifOperStatus
   1  loup   up
   2eth0up   up
   3eth1up   up
   4eth2up down
   5eth3up down
  24 ;vdsmdummy;  down down
  25   vnet0up   up


And indeed on the server:

ip link show eth2
4: eth2:  mtu 1500 qdisc mq state DOWN mode 
DEFAULT group default qlen 1000
link/ether 40:a8:f0:30:81:1a brd ff:ff:ff:ff:ff:ff


It's up, but I don't configured it on oVirt, removed ifcg-eth2. Is there a way 
to disable it ?___

[ovirt-users] Re: Is enabling Epel repo will break the installation?

2018-07-24 Thread Fabrice Bacchella

oVirt developpers are not big fan of epel anyway. So don't expect this 
situation to change soon.

To be sure that epel don't interfere in any way with oVirt epel, rather than 
excluding collected, I changed the priority of oVirt's epel:

in /etc/yum.repos.d/ovirt-4.2-dependencies.repo
[ovirt-4.2-epel]
...
priority=10

The default priority is 99, so whatever package ovirt choose to add in it, it 
will win other epel.

[ovirt-users] Xen Free Edition migration to oVirt

2018-07-24 Thread Sandro Bonazzola

Hi,
If you were using Xen Free Edition or if you are still using it, after
https://xenserver.org/blog/entry/xenserver-7-3-changes-to-the-free-edition.html
you may be looking at oVirt as alternative.
A community tool to ease the migration exist here:
https://github.com/zipurman/oVIRT_Simple_Backup.
Did you migrate to oVirt or are you planning it?
I was wondering if it may help organizing an hackathon day for helping
users doing the migration would make sense, so I'd like to know if there
are users looking for assistance in the migration process.
Let us know!

It's not, but you can write a script which can do this. But if you want
all users from the ldap are able to login I would suggest to you create
some group in LDAP and add all users as a member of this group and add
this group to ovirt and assign it the permissions.
