[ovirt-users] Can't remove snapshot

[Rik Theys]

Hi,

In the mean time I've noticed the following entries in our periodic
logcheck output:

Feb  3 09:05:53 orinoco journal: block copy still active: disk 'vda' not
ready for pivot yet
Feb  3 09:05:53 orinoco journal: vdsm root ERROR Unhandled
exception#012Traceback (most recent call last):#012  File

('virDomainBlockJobAbort() failed', dom=self)#012libvirtError: block
copy still active: disk 'vda' not ready for pivot yet

This is from the host running the VM.

Note that this host is not the SPM of the cluster. I always thought all
operations on disk volumes happened on the SPM host?

My question still remains:
