Hi All Possibly a dumb question, but given with cephfs you can apply quotas to arbitrary directories, snapshot arbitrary directories, assign arbitrary directories to pools etc. what is special/different about subvolumes, and why would I want to use them (and more importantly, not want to use them)? I guess the only thing I can see could be around where the extended attributes are assigned (with the two-level directory structure enabling setting a quota while not allowing read access to the directory above, based on looking at the cephfs CSI?), but I feel I'm missing something obvious. The specific usecase I'm looking at is evaluating using just quotas vs subvolumes for team shares (to ensure that each team only uses the amount of storage they require), but in general I'm trying to understand subvolumes.
