+++ This bug was initially created as a clone of Bug #1492473 +++ Description of problem: Setting of High Availability properties cause Tasks window to hang up Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1.create VM, run , open 'High Available' tab, check High Availability box and choose nfs_2 from drop down list, ok brings a message that VM must be restarted. 2.poweroff the VM. Open the 'High Available' again. change the nfs_2 to nfs_1. ok 3.run VM Actual results: In tasks tab (right upper corner) you see the 'Editing VM properties' task in 'Finalizing' state which just hangs up and never ends. the only way is remove job_id from job table of postgres , and then restart engine Expected results: VM is started with new High Available settings Additional info: sometimes you have to repeate the scenario (open High Availability tab/run VM) twice to reproduce --- Additional comment from Polina on 2017-09-17 11:38 EDT --- --- Additional comment from Tomas Jelinek on 2017-09-18 02:39:37 EDT --- please always attach engine and vdsm logs to bug reports --- Additional comment from Polina on 2017-10-02 10:11 EDT --- --- Additional comment from Tomas Jelinek on 2017-10-06 07:01:57 EDT --- There are simpler steps to reproduce: - create VM - edit VM and set it as HA with lease on SD1 - save - (quickly) edit again and change the lease to SD2 The problem looks like a regression from https://gerrit.ovirt.org/#/c/72120/ Before that patch, the vm lease commands were sync so the VM was locked while running this commands. Since that patch the lease commands are async and take a while to run, but the VM is for some reason not locked. And since the VM is not locked, it is possible to run an another edit (even of the lease) on it. This race causes the jobs not being finished properly. Moving to storage for further investigation. --- Additional comment from Polina on 2017-11-21 03:49:10 EST --- the negative effect of the bug even worse, since after this the leases in HA tab disappear. impossible to choose HA lease.
Tested and when running the next scenario: - create VM - edit VM and set it as HA with lease on SD1 - save - (quickly) edit again and change the lease to SD2 i get a message: "Error while executing action: <name of vm>: Cannot edit VM. VM is being updated." Tested using: ovirt-engine-4.2.1.1-0.1.el7.noarch Moving to VERIFIED
