Hi,
Given a cluster with multiple racks or rooms where the rack or room is
the failure domain for replicated pools.
Given one or more CephFS volumes (filesystems) with at least one active
MDS each and a standby-replay for each active MDS.
Each room or rack contains multiple MDS daemons (one per host).
Is there a possibility to guarantee that the standby-replay MDS for each
active MDS does not run in the same failure domain (rack or room)?
Because when both run in the same failure domain and that domain fails
there is no point in having a standby-replay.
Are there any ideas on how to solve this?
Regards
