[ovirt-users] VM doesn't start after storage migration (Logical volume does not exist)

[s k]

Hello,


I performed a storage migration of a CentOS 6 VM and while the migration was succesfull (based on the output in the tasks tab on the bottom of the webadmin portal) the Disks on the VM's tab weren't refreshed with the new Storage Domain information and remained locked.


I removed the lock by running "update images set imagestatus = 1 where imagestatus = 2;" on the database but the storage domain wasn't updated to the new one and kept the original location.


Now I'm unable to start the VM probably because the disks have been migrated but the information on the database stills points on the old storage domain.


The vdsm log throws the following error at VM startup:


Thread-887::ERROR::2015-04-17 10:08:11,831::task::866::Storage.TaskManager.Task::(_setError) Task=`7b51e15b-b04f-4f17-8096-882beffc1a6f`::Unexpected error

Similarly the engine log throws the following error:

How can I fix this? Do I have to edit the database? How can I find which is the correct logical volume associated with the VM?


Thank you,
