Hi Robert!
Thanks for the feedback! I am aware of the fact that the number of the
monitors should be odd
but this is a very basic setup just to test CEPH functionality and
perform tasks there before
doing it to our production cluster.
So I am not concerned about that and I really don't believe that this
is why the problem has appeared!
What concerns me is how this "new" monitor that has the same name
followed by an underscore and
the IP address appeared out of nowhere and how to stop it!
Regards,
George
Two monitors dont work very well and really dont but you anything. I
would either add another monitor or remove one. Paxos is most
effective with an odd number of monitors.
I dont know about the problem you are experiencing and how to help
you. An even number of monitors should work.

Hi all!
I have updated from 0.80.8 to 0.80.9 and every time I try to
restart
CEPH a monitor a strange monitor is appearing!
Here is the output:
#/etc/init.d/ceph restart mon
=== mon.master ===
=== mon.master ===

mon.master_192.168.0.10@-1(probing) e2 commit suicide!
2015-03-13 03:06:22.964499 7f06256fa7a0 -1 failed to initialize

master_192.168.0.10
--pid-file /var/run/ceph/mon.master_192.168.0.10.pid -c
/etc/ceph/ceph.conf --cluster ceph
I have two monitors which are:
mon.master and mon.client1
and have defined them in ceph.conf as:
mon_initial_members = master,client1
mon_host = 192.168.0.10,192.168.0.11
Why is the "mon.master_192.168.0.10" appearing and how can I stop
it
from happening?
The above is the problem on one node. Obviously the problem is
appearing on the other node as well but instead I have
"mon.client1_192.168.0.11" appearing
Any ideas?
Regards,
George
