This is on the agenda for CDM next week, but I wrote up some notes here:
https://pad.ceph.com/p/cephfs-snap-mirroring
It encompasses a few things besides just mirroring, starting with a set of
comamnds to set up cephfs snapshot schedules and retention/rotation
policy, which we need anyway, and seems related and like something we
should add before doing mirroring.
Thoughts?
Yay! I actually wanted to start on this this summer, so a) glad it's on the
agenda and b) I'd be more then happy to work on it.
I left some comments in the etherpad. Generally I think it makes sense to
separate the snapshot scheduling (and the accompanying pruning) and the
mirroring. These two features are not really interdependent bur rather (can)
work in concert. And some user might want to mirror their manual snapshots or
not mirror at all.
Looking forward to Wednesday!
