Dear All...
Maybe the issue I am about to report is already found by some of you. If
yes, sorry for the duplication.
I spent a lot of time understanding why my mons were not in good
condition. ceph service was up and running, but I noticed the following
process hanging... A clean installation would always generate the same
situation:
python /usr/sbin/ceph-create-keys --cluster ceph -i <fqdn>
It took me some time to understand that the problem was because i was
creating my monmap using the hosts fqdn, and initializing the ceph mon
data also using the fqdn. Something like:
# monmaptool --create --add <fqdn> <ip> --fsid `grep fsid
/etc/ceph/ceph.conf | cut -f3 -d' '` /tmp/monmap
monmaptool: monmap file /tmp/monmap
monmaptool: set fsid to a9431bc6-3ee1-4b0a-8d21-0ad883a4d2ed
monmaptool: writing epoch 0 to /tmp/monmap (1 monitors)
# ceph-mon --mkfs -i <fqdn> --monmap /tmp/monmap --keyring
/tmp/ceph.mon.keyring
That simply makes things crazy in 0.94.1.
Once I substituted the fqdn by simply the hostname (without the domain)
it worked.
Cheers
Goncalo
