Hi I have a worst case,
osd's in a 3 node cluster each 4 nvme's won't start
we had a ip config change in public network, and mon's died so we
managed mon's to come back with new ip's.
corosync on 2 rings is fine,
all 3 mon's are up
osd's won't start
how to get back to the pool, already 3vm's are configured and valuable
data would be lost...
this is like a scenario when all systemdisks on each 3 nodes failed, but
osd disks are healthy ...
any help to reconstruct this storage is highly appreciated!
Gerhard
