This is a symptom of inaccessible storage. Sanlock failed to write to
the "ids" file.

We need to understand why sanlock failed. If the partialy created domain is
still available, this may explain the issue:

ls -lhZ /rhv/data-center/mnt/server:_path/storage-domain-uuid/dom_md

ps -efz | grep sanlock

ausearch -m avc
