Description of problem:
VM clone with this scenario running with Kaninario backend fails and the file-based disk does not roll back and stay in 'LOCKED' state:

clone VM 'vm1_clone' is created but without ANY disks -> not file-based disk neither block managed SD disk.

Engine log:

How reproducible:

Steps to Reproduce:
1.Create a Kaminario managed block SD
2.Create a VM with 2 disks(file based disk and a managed block storage disk from SD of step 1)
3.Clone the VM

Actual results:
Clone VM fails and the file base disk remains stuck in 'Locked' state.

Expected results:

Additional info:
I tested with HP3PAR, Netapp and CEPH, and this flow work, issue seen only on Kaminario.

Comment 1 Benny Zlotnik 2019-03-11 10:27:24 UTC
We need to improve the failure handling, but regardless, it is not possible to perform any operation that perform clone volume with the kaminario backend as it uses host-assisted copy
