We cherry-pick only blockers since 7af278756a11f94d00ae2066f0e0a4db76442999 If this is a release blocker, we need to add that to the known blockers. The commit should solve described issue, the similar problem to Dafna's was also found due internal testing and was fixed with out any opened a new bug, so I think these is a reason that bug was not defined as blocker and was not cherry picked fixed: http://gerrit.ovirt.org/#change,1126 http://gerrit.ovirt.org/gitweb?p=ovirt-engine.git;a=commit;h=7eb04bb3a869daf97d2f4ec232c463cc4ce44461 and cherry-picked: http://gerrit.ovirt.org/#change,1392 closing ON_QA bugs as oVirt 3.1 was released: http://www.ovirt.org/get-ovirt/ |
Created attachment 558295 [details] log Description of problem: after trying to create a snapshot while same operation is already started, will cause a lock issue which will prevent from creating snapshot for the vm even when the vm is no longer in image lock. 2012-01-30 11:45:25,526 INFO [org.ovirt.engine.core.bll.CreateAllSnapshotsFromVmCommand] (http--0.0.0.0-8080-3) Failed to Acquire Lock to object EngineLock [exclusiveLocks= key: org.ovirt.engine.core.bll.CreateAllSnapshotsFromVmCommand value: ba681f03-5c6e-483d-9265-504c90042388 seems like this might be a db issue since we are able to delete snapshots and perform other actions. seems like lock might not be cleared in db. Version-Release number of selected component (if applicable): ovirt-engine-backend-3.0.0_0001-1.4.fc16.x86_64 How reproducible: 100% Steps to Reproduce: 1. create a snapshot and before vm gets into image locked try to create another snapshot 2. after the vm finished creating the first snapshot -> try to create a snapshot again 3. Actual results: we get an error in web admin and log shows Failed to Acquire Lock to object EngineLock Expected results: we should be able to create a snapshot Additional info:full log
