Hi,
There's something I don't understand about the exclusive-lock feature.

I have weird behaviour on my firefly "test + convenience storage"

Hi,
I have a pretty big problem here... my OSDs are marked down (except one?!)
I have ceph ceph version 0.61.8 (a6fdcca3bddbc9f177e4e2bf0d9cdd85006b028b).
I recently had a full monitors so I had to remove them but it seemed to
