Hi list,
Had a power outage killing the whole cluster. Cephfs will not start at all, but RBD works just fine.
I did have 4 unfound objects that I eventually had to rollback or delete which I don't really understand as I should've had a copy of the those pbjects on the other drives?
2/3 mons and mgrs are damaged but without any errors.
I have loads stored on cephfs so would very much like to get that running as a first priority.
Thanks!
Alex
Info about the home cluster:
I run 23 osds on 3 hosts. 6 of these are a SSD cache layer for the spinning rust, as well as the metadata portion for cephfs which in retrospect might have to be put back on the spinning rust.
