Hi,
During an upgrade from pacific to quincy, we needed to recreate the mons
because the mons were pretty old and still using leveldb.
So step one was to destroy one of the mons. After that we recreated the
monitor, and although it starts, it remains in state ‘probing’, as you
can see below.
No matter what I tried, it won’t come up. I’ve seen quite some messages
that the MTU might be an issue, but that seems to be ok:
root@proxmox03:/var/log/ceph# fping -b 1472 10.10.10.{1..3} -M
10.10.10.1 is alive
10.10.10.2 is alive
10.10.10.3 is alive
Does anyone have an idea how to fix this? I’ve tried destroying and
recreating the mon a few times now. Could it be that the leveldb mons
only support mon.$id notation for the monitors?
