This often produces to me too. The only way I found to resolve it is to restart engine, you may try this, it has no impact on the host and vms.Hi NathanaëlI try it today and the snapshot was in the state "OK" after I execute the script. I try to remove the snapshot again, but it never do something. So after I click "Delete", i have this situation:Tasks(1):- (Hourglass) Removing Snapshot Auto-generated for Live Storage Migration of VM xxxx-- (Completed) Validating -- (Hourglass) Executing The snapshot is in the status "Locked" This status remains for ever.When I restart the engine, the Status is still in the status "Locked", but the task no longer exists.engine.log:2016-05-18 16:33:07,532 INFO [org.ovirt.engine.core.bll.RemoveSnapshotCommand] (default task-23) [53281b57] Lock Acquired to object 'EngineLock:{exclusiveLocks='[2acfe3fa-be69-46da-9add-c748b2bd6034=<VM, ACTION_TYPE_FAILED_OBJECT_LOCKED>]', sharedLocks='null'}'2016-05-18 16:33:08,640 INFO [org.ovirt.engine.core.bll.RemoveSnapshotCommand] (default task-23) [53281b57] Running command: RemoveSnapshotCommand internal: false.

Mai 2016 19:23 An: users@ovirt.orgBetreff: [ovirt-users] Snapshot is "Locked" - Can't do anything with the VMHi oVirt ListWe have the problem, that two of our VM's have "Locked" snapshots and we can't go forward. From 10 VM's which we move from one store to another, we have problems with 5 of them to delete the snapshots. But with a lot of luck, the snapshot was always on the dedicated Swap-Disk, so we justhave to remove the whole disk and create it again as new.Because we replace all the filers, we have to move the VM's arround. The move itself runns fine, but deleting the snapshots doesn't work sometimes.I found a lot about our problem, but I can't find any solution, which works an our environment. Our setup: - 3 Solaris filer with NFS exports for the hosts for the vm-images - 8 hosts (oVirt 3.6 / Centos 7.2.1511) - The engine host is located outside of the DC, connected via VPN At the moment, one of the "problem-VM" is productive, the other should become productive in the next days, so we focus us to the 2nd VM,because we can play arround with them. The other one is startet up, buti have no idea, what happens, when i shut them down... This is the status today of VM, which is not productive at the moment: - VM Status: Down - Snapshots OK: 2 - Snapshots Locked: 1 - In the snapshot tab, everything is grayed out (Create, Preview, Commit, Undo etc.) - No active tasks are displayed Error message when i try to start the VM:"Cannot run VM. The VM is performing an operation on a Snapshot. Pleasewait for the operation to finish, and try again."
Something about the history of this VM: 1. We start the disk move from filer1 to filer3, totaly 4 drives, everything was fine 2. Deleting snapshots, i think one or two runns fine 3. Deleting the 2nd or 3rd snapshot runs two days without an end 4. Rebooting the Engine 5. No task anymore in the Tasks list 6. The status of the snapshot is "Locked", die Disk of this snapshot becoms "Illegal" and red 7. Shutdown the VM - no luck, i can't start it again --> "Cannot runVM. The VM is performing an operation on a Snapshot. Please wait for theoperation to finish, and try again." 8. We move the disk back from filer3 to the filer1 9. The status of the snapshot is "Locked", die Disk of this snapshot becoms "OK" and green ...but i can't delete the snapshot or starting the VM :( Today, i copy the image files to a dedicated KVM host, which is notinvolved in the oVirt environment and i merge the image manualy together: qemu-img convert -p -f qcow2 804ffcc3-446f-4c56-ba99-ab90c7951a6f -O rawMerged1I mount the image and everything fine, all the changes from the last twodays are now in a base image. I try to remove the whole disk in oVirt, but i still got the error message, that i have to wait. So for me, the next step is to create a new VM and migrate everything manualy, this will work, but can't be the solution for the other VM, which is productive and it have the same problem.
