Comment 2 for bug 1541946

This is a really strange error. It looks like disks just left the node during the test. Look at the blkid output, it looks like there is no disks that could have been used as ceph partitions. For me it seems like buggy hardware or some other libvirt issues on the node that was used. I would also consider the issue to be due to some purge happenning on the host node, e.g. that the disks were purged or ejected from the VM.
