Joao,

is running now. It hit 52MB very quickly then nothing with lots of disk
read, which is what I’d expect. Its reading fast and expect it to finish
in 35min.
Just to make sure, this won’t add a new monitor, just clean it up. So,
when it’s done I should do the following:
mv /var/lib/ceph/mon/ceph-2 /var/lib/ceph/mon/ceph-2.old
mv /var/lib/ceph/mon/ceph-1 /var/lib/ceph/mon/ceph-2
service ceph start mon.2
Correct. The tool just extracts whatever is on one mon store and copies
it to another store. The contents should be the same and the monitor
should come back to life as if nothing had happened.
If for some reason that is not the case, you'll still have the original
store readily to be used. Let me know if that happens and I'll be happy
to help.
