[pve-devel] [PATCH storage 1/2] rbd plugin: status: drop outdated fallback

[Fiona Ebner]

As commit e79ab52 ("Fix #2346: rbd storage shows wrong %-usage")
mentions, Ceph provides a 'stored' field since version 14.2.2 as an
approximation of the actually stored amount of user data. The commit
forgot to update the accompanying comment however.

The 'bytes_used' field refers to the raw usage without factoring out
replication (default: 3). The 'max_avail' value is after factoring out
replication, so using 'bytes_used' in the same calculation would lead
to very confusing results.
