Re: [Users] VMs and volumes disappearing
Hello Yair, Thank you for your answers, but I still have some questions left ;-)
I find engine.log somewhat hard to read, to be honest, and documentation is hard to find, but I think I found some clues.
Hi, I understand what you're saying about engine.log, when I asked for it, it was because I'm one of the maintainers of ovirt engine, so I thought I could give you a hand here, especially after reading your email and getting a sense that I saw a similar issue in the past.
If you want, I can send you my log. I wasn't sure if that's what you meant. I just had the same problem again. - Stopped oVirt engine - Checked the 'async_tasks' table. It was empty! - Started oVirt engine - Same set of imported VMs as last time deleted! I thought that lingering records from the 'async_tasks' table were to blame, but apparently, that's not the case. Can you tell me what I need to check/do/modify/update/delete before restarting oVirt that will keep my VMs from being deleted? (Please see below for a note on upgrading like you suggested)
I think I have an idea about what happended now.
The 2 disappeared VMs have been imported into oVirt using virt-v2v. The 3rd one that's now missing a disk volume was not, but I have been playing with storage migration in the past.
Then this is the reason, other users have complained about it at users@ovirt.org
I have read the thread about disappearing VMs from August and indeed it sounds like this might me the same problem.
Upgrade I just talked with Ofer (CC'ed), our release engineer, and he said that all packages should be 3.3.0-4 (notice ovirt-engine is not) I hope this helps you out,
There are no updates, at least Yum doesn't give me any. I enabled the beta channel just now, but that doesn't make a difference. 3.3.0-1 is the latest version. What am I missing? martijn@ovirt:~> sudo yum list all|grep ovirt-engine.noarch ovirt-engine.noarch 3.3.0-1.el6 @ovirt-beta Best regards, Martijn Grendelman

make sure you dont have records at async_tasks with vdsm_task_id of "empty guid" - but i'm really not in favor of such hacks, this is a hack. I strongly suggest you solve upgrade issue (please communicate with ofer on this).

The 2 disappeared VMs have been imported into oVirt using virt-v2v. The 3rd one that's now missing a disk volume was not, but I have been playing with storage migration in the past.

martijn@ovirt:~> sudo yum list all|grep ovirt-engine.noarch ovirt-engine.noarch 3.3.0-1.el6 @ovirt-beta
I'll let ofer answer that.

you should run ovirt-check-update and ovirt-engine-upgrade (or ovirt-engine-setup) to get updates for engine. we use version lock to prevent yum for updating the rpm without proper sync of db/backup/rollback.
In order to upgrade, it would be 'engine-setup' :-) -- Best regards, Alex Lourie Software Developer in Integration Red Hat ----- Original Message -----
