Stalled disk migration
by Nicolás 09 Oct '16

09 Oct '16

Hi, We've done a major datastore migration recently between 2 iSCSI-based datastores. We've successfully migrated 35 machines, however, 5 of them seem to have stalled. All we can see in the events tab tab is: Moving Disk bla_Disk1 from iscsi01 to iscsi02 Disks are small enough (25-27Gb) to assume this won't progress since it's been more than 30 hs. since the migration began, other VMs took approximately 1-1.5 hours to fully migrate a disk, so this seems to be stalled. The bad thing is that I can't find a way to "unstall" it. Disks are in a perpetual "migrating" status and there's no way to stop the migration (at least from the webadmin). I don't actually care if stopping the migration breaks those 5 machines since they are disposable, I just need to stop that event. I already tried restarting the ovirt-engine and it didn't work. Log doesn't seem to provide nothing relevant. Is there a way to do that? I wouldn't mind if I need to modify some record directly into the DB. Thanks! Nicolás

They are to be removed soon. In fact we already stopped them to track the remaining users, and no one complained. It can be restarted on demand before the removal date. On 2016-10-26 the resources will be purged. Backup has been made, so nothing is lost but unless there is a good reason it won't be used. Btw, the wiki@ mailing-list was unused and is now read-only.

documentation change suggestion / question
by Charles Kozler 08 Oct '16

08 Oct '16

Googling "ovirt windows agent" this is the first link that pops up: http://www.ovirt.org/documentation/internal/guest-agent/guest-agent-for-win… This doc seems non-intuitive and over complicated Specifically, the RedHat documentation that is 4 links below is simple as "install this package and mount the iso": https://community.redhat.com/blog/2015/05/how-to-install-and-use-ovirts-win… The former was updated as early as June of this year 1.) The RedHat document worked for me so I dont think oVirt 4.x cant use the same 2.) Why have separate areas of documentation that are so different from each other? This has caused me issues in the past whereby I found RH docs that were much more clear and concise 3.) Is there anyone who might want to merge RH docs with oVirt docs where the RH docs are better than oVirt? Thanks so much for providing such a great product! I just feel sometimes the docs are a little more developer-centric whereas the RedHat docs are more easily readable

VMs paused due to IO issues - Dell Equallogic controller failover
by Gary Lloyd 07 Oct '16

07 Oct '16

Hi We have Ovirt 3.65 with a Dell Equallogic SAN and we use Direct Luns for all our VMs. At the weekend during early hours an Equallogic controller failed over to its standby on one of our arrays and this caused about 20 of our VMs to be paused due to IO problems. I have also noticed that this happens during Equallogic firmware upgrades since we moved onto Ovirt 3.65. As recommended by Dell disk timeouts within the VMs are set to 60 seconds when they are hosted on an EqualLogic SAN. Is there any other timeout value that we can configure in vdsm.conf to stop VMs from getting paused when a controller fails over ? Also is there anything that we can tweak to automatically unpause the VMs once connectivity with the arrays is re-established ? At the moment we are running a customized version of storageServer.py, as Ovirt has yet to include iscsi multipath support for Direct Luns out of the box. Many Thanks *Gary Lloyd* ________________________________________________ I.T.
