Hi
I have a Luminous cluster of 5 servers: from server1 to server5.
The operating system is Devuan.
There are three monitors: server1, server3, server5.
I'm trying to add a new monitor to server2 manually:
mkdir /var/lib/ceph/mon/ceph-server2
ceph auth get mon. -o mon.keyring
ceph mon getmap -o mon.map
ceph-mon -i server2 --mkfs --monmap mon.map --keyring mon.keyring
touch /var/lib/ceph/mon/ceph-server2/done
touch /var/lib/ceph/mon/ceph-server2/sysvinit
chown -R ceph:ceph /var/lib/ceph/mon/
After the monitor is started on the server2, the cluster loses one of
the monitors in the quorum and the elections begin. a new monitor is not
added.
Until I stop the new monitor service, one of the monitors is always in
DOWN and the elections are continuously generated.
It seems to me that the new monitor is trying to replace the existing one.
NTP looks is good.
I can show the level 20 monitors logs and any additional information
about the cluster.
I will be grateful for any thoughts that will help me understand and
solve this problem.
Regards,
Alexander
