Hi,

even better is to set allow_standby_replay and have for example 2 active and 2 standby. More here https://docs.ceph.com/en/latest/cephfs/standby/#configuring-standby-replay

Dear Cephers,

When setting up multiple active CephFS MDS, how to make these MDS high 
available? i.e. whenever there is failed MDS, another MDS would quickly take 
over. Does it mean that for N active MDS, I need to set up N standby MDS, and 
make one standby MDS associated with one active MDS?

What would be the best practice for high availability with multiple active MDS?

best regards,

samuel
