Hi guys. Is this ok & expected that standby MDS for a filesystem looks as such: -> $ ceph fs status APKI APKI - 4 clients ==== RANK STATE MDS ACTIVITY DNS INOS DIRS CAPS 0 active APKI.podster2.gsniot Reqs: 0 /s 8505 5516 143 2757 POOL TYPE USED AVAIL cephfs.APKI.meta metadata 671M 74.0G cephfs.APKI.data data 16.1G 74.0G STANDBY MDS APKI.podster3.utwwpp MONERO.podster3.gwtegj MDS version: ceph version 20.1.1 (dd9c546413d50a90668289255a256022ea21f0c0) tentacle (rc - RelWithDebInfo) What puzzles me from that above is: MONERO.podster3.gwtegj I have only two files systems - this is a small lab with ceph - and both were created with "default" ceph cmd, meaning that pools where created automatically by cmd. Is there no special and exclusive relationship between file system & MDS - MONERO.podster3 was created when file system/volume MONERO was created, yet it is available to a different file system? (what also boggles my mind is "size" the two file systems report, like they share something, but not relevant yet in case I have something seriously dis-configured relating what stat "status" showed) many thanks, L.
