So the only tool we have to clean metadata is '–clean-metadata', which
works one-by-one?

Doesn't cleaning sanlock lockspace require also to stop sanlock itself?
I guess it's supposed to be able to handle this, but perhaps users want
to clean the lockspace because dirt there causes also problems with
sanlock, no?
