CEPH Community!
Cheers to 2020
We have a single cluster running in two modes: CephFS as mountable filesystem and Rados
Object Gateway (S3 like for storing objects) - all good there no questions, CEPH is
awesome!
Were planning to get 2nd cluster in a different Datacenter and have both clusters
connected / replicated / mirrored (e.g. multi-site).
Is there a way to achieve that for CephFS and Rados modes, any ideas / recommendations /
best practices / articles someone can share? Any insight would be much, much appreciated!
P.S. The RBD mirroring which seemed like is the solution - went as far as discovering that
RBD mirroring works for block devices only, can’t be used with CephFS. There are some
references as to Rados supporting multi-site with potentially significant impact on write
latency.
Thanks,
Eduard
