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 This bugzilla is included in oVirt 4.4.3 release, published on November 10th 2020. Since the problem described in this bug report should be resolved in oVirt 4.4.3 release, it has been closed with a resolution of CURRENT RELEASE. If the solution does not work for you, please open a new bug report. |
Created attachment 1541712 [details] engine and vdsm logs 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.

Version-Release number of selected component (if applicable): 4.3.2.1 How reproducible: 100% 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.
