Yes, this seems to be a bug when doing a merge on a host which is not
the spm.
According to the log you attached (vdsm.log.5):
- we do not deactivate the lv after the merge
- therefore the link /dev/vgname/lvname is not deleted
- we don't delete the link at /rhev/data-center
- we don't delete the links at /run/vdsm/storage
The links under /run/vdsm/storage and /rhev/data-center should will
be deleted when hotunpluging this disk, or when stopping the vm.
Please file a ovirt/vdsm bug for this and include the information
from this thread.
