Hello
We are having troubles with kvm snapshots. Our architecture: hosts
CentOS 6.4, Primary storage - iscsi; secondary storage - nfs over iscsi
from management.
For primary storage we have tried clvm and sharedmountpoint (gfs2,
ocfs2) with the same result.
Everything is working fine until there is only one active host in cloud.
When second host is added some snapshots fail with state
"CreatedOnPrimary". Failed snapshots are visible with virsh.
virsh snapshot-list i-2-33-VM
Name Creation Time State
------------------------------------------------------------
ee9302c6-bd00-4b93-aa77-f05d5a9a44c6 2013-10-24 13:56:24 +0300 running
VM with unsuccessful snapshot gets stuck until snapshot is manualy
deleted. It can be easily deleted with virsh.
We have tried upgrading libvirt and/or qemu versions with the same
result. Snapshots are running good only with nfs mounted primary
storage.
I realy do not no if we are missing something or it is a bug of kvm.
Has somebody managed to setup kvm with working snapshots on clvm or
sharedmountpoint?
We will appreciate any help. Thanks in advance.
