[ovirt-users] Can't remove a storage domain related to a broken hardware
Hello Ovirt users ! I experienced an hardware failure on a ISCSI storage making it unrecoverable, and I would like to remove it from storage domains. There was 1 disk on this storage domain, and this disk isn't attached to any VM anymore, but I still can't detach this storage domain from cluster. The storage domain is in inactive status and if I try to detach it from data center, ovirt tries to activate it. Obviously it can't activate it since hardware is broken, and it fails after several minutes with the event Failed to detach Storage Domain my_storage_domain to Data Center Default. (User: admin). I can post my engine.log if useful. I need a way to force removal of this storage domain. Any trick would be greatly appreciated. Perhaps does Ovirt miss some sort of force detach, i know what i'm doing button ? I am running an Ovirt 3.5 cluster (engine with CentOS 6.6, 4 nodes with CentOS 7) with FC and ISCSI storage domains.

I see that this kind can be happen, because migration time exceeding the
configured maximum time for migrations, but anyway we need help from devs, I
added some to CC.
- agent did everything correctly and as Artyom says, the migration is
aborted by vdsm:
The migration took 260 seconds which is exceeding the configured maximum
time for migrations of 256 seconds. The migration will be aborted.
- there is a configuration option in vdsm conf you can tweak to increase
the timeout:
snip
'migration_max_time_per_gib_mem', '64',
'The maximum time in seconds per GiB memory a migration may
take '
'before the migration will be aborted by the source host. '
'Setting this value to 0 will disable this feature.'
/snip
So as you can see in your case it's 4 * 64 seconds = 256seconds.

I collected the agent.log and vdsm.log in 2 cases.
Case1 HE VM failover trail
What I did
1, make all host be engine up
2, set host1 be with local maintenance mode. In host1, there is HE VM.
3, Then HE VM is trying to migrate, but finally it fails. This can be found
from agent.log_hosted_engine_1
As for the log is very large, I uploaded into google dirve. The link is as

The logs are for 3 hosts in my environment.
Case2 non-HE VM failover trail
1, make all host be engine up
2,set host2 be with local maintenance mode. In host3, there is one vm with ha enabled. Also for the
cluster, Enable HA reservation and Resilience policy is set as migrating virtual
machines
3,But the vm on the top of host3 does not migrate at all.
The logs are uploaded to good drive as

Re: [ovirt-users] Would you add the project of Jasper into the Zanata?
Hi Helen, Sorry for the delay in responding. With regard to the JasperServer strings for oVirt Reports, we have two projects in zanata.org. The first one is oVirt Engine Reports which you have already edited some translations. The second one is oVirt Engine DWH, accessible at: https://translate.zanata.org/zanata/project/view/ovirt-engine-dwh (there is only one version called master in this project) The remaining translations are actually imported from the JasperServer community. If you would like to change those strings, the only way to change them is to be part of JasperServer localization group and work with them. Yaniv and Shirly are able to direct you to the right contact. I also confirmed with Shirly that the recent fix you applied in oVirt Engine Reports (and potentially oVirt Engine DWH) will first be included in 3.6, then backported to 3.5.2.

Re: [ovirt-users] HostedEngine Deployment Woes
Thanks for the tip. That seemed to work and after fixing my nfs issues and removing that config the hosted setup completed to the point of creating the vm and waiting for the os to be installed on it, however... I try to connect to the vm via vnc and it just flashes and closes vnc. Vnc log indicated an unexpected close. We're are the logs for the vnc server end of things so I can see why it's closing the session?

Basically, I'd like to: Tell VM to flush it's buffers suspend VM take snap shot of boot virtual disk resume VM You don't need to suspend the vm, qemu can create live snapshot. When the snapshot is done, you don't care about future io, it will simply not included in the backup. backup the virtual boot disk from the Hypervisor using standard commands (tar, cp, whatever) You can by attaching the snapshot to another vm destroy the snapshot You can in ovirt 3.5.1 - we do not depend any more on future libvirt features. Adam, can you confirm? Yes, on 3.5.1 you'll be able to destroy the snapshot without impacting the running VM. This would at least give some BMR capabilities of your VMs. Ideally, I'd also like to be able to create a snapshot from within the VM, do You can do this within the vm by using the engine REST API. But this can be fragile - for example, if the vm pauses, your backup tool within the vm will never complete :-) a yum update, see if I like it or not, if I do, then destroy the snap shot. Possible in 3.5.1 using REST API If I don't, I want to promote the snapshot and boot from that, then destroy the original.
