Hi,
maybe you can try this,
--see whether your third monitor exist in ceph
Root# ceph mon dump
dumped monmap epoch 12
epoch 12
fsid b3ecd9c5-182b-4978-9272-d4b278454500
last_changed 2013-10-23 17:57:44.185915
created 2013-05-16 16:46:00.572157
0: 10.xxx.xxx.xx1:6789/0 mon.0
1: 10.xxx.xxx.xx2:6789/0 mon.1
2: 10.xxx.xxx.xx3:6789/0 mon.2
--get monmap
Root# ceph mon getmap -o /tmp/monmap
got latest monmap
--inject your new mon, change 2 with your mon name
Root# ceph-mon -i 2 --inject-monmap /tmp/monmap
restart the third monitor
regards

And this is the ceph.conf:
[global]
fsid = 0615ddc1-abff-4fe2-8919-68448b9f6faa
mon_initial_members = ceph2, ceph3, ceph4

Thanks.
