Standby MDS is required for HA. It can be configured in standby-replay mode for
faster failover. Otherwise, replaying the journal is incurred which can take
somewhat longer.

Thanks for your response.

recomended or recovery is fast enought to be useful?

Hello,
I'm trying to create a simple cluster to archieve HA on a webpage:
- Three nodes with MDS, OSD, MON, y MGR
- Replication factor of three (one copy on every node)
- Two active and a backup MDS to allow a fail of one server
- CephFS mounted using kernel driver
- One disk by no
