Hi,
Thanks for the interesting discussion. Actually it's a bit
disappointing to see that also cephfs with multiple MDS servers is
not as HA as we would like it.
it really depends on what you're trying to achieve since there are
lots of different scenarios how to setup and configure one
Hi all,

I read also that filover time depends on the number of clients. We will
only have three, and they will not do heavy IO. So
Just one comment on the standby-replay setting: it really depends on
the use-case, it can make things worse during failover. Just recently
we had a customer where disabling standby-replay made failovers even
faster and cleaner in a heavily used cluster. With standby-replay they
had to
I use this very example, few more servers. I have no outage windows for my
ceph deployments as they support several production environments.
MDS is your focus, there are many knobs, but MDS is the key to client
experience. In my environment, MDS failover takes 30-180 seconds,
