Hi, I recently (yesterday) upgraded to Luminous (12.2.1) running on Ubuntu 14.04.5 LTS. Upgrade went fine, no issues at all. However when I was about to use ceph-deploy to configure some new disks it failed. After some investigation I figured out that it didn't like that my mons was named ceph03mon on the host ceph03 for example, ceph-deploy gatherkeys ceph03 failed. So I decided to rename my mons. I started with removing one of them:
# stop ceph-mon id=ceph03mon # ceph mon remove ceph03mon # cd /var/lib/ceph/mon/ # mv ceph-ceph03mon disabled-ceph-ceph03mon Created the new one: # mkdir tmp # mkdir ceph-ceph03 # ceph auth get mon. -o tmp/keyring # ceph mon getmap -o tmp/monmap # ceph-mon -i ceph03 --mkfs --monmap tmp/monmap --keyring tmp/keyring # chown -R ceph:ceph ceph-ceph03 # ceph-mon -i ceph03 --public-addr 10.10.1.23:6789 # start ceph-mon id=ceph03 Starts OK, quorum is established, when it gets the command "ceph osd pool stat" for example, or "ceph auth list" it crashes. Complete log can be found at: http://files.spacedump.se/ceph03-monerror-20171106-01.txt Used below settings for logging in ceph.conf at the time: [mon] debug mon = 20 debug paxos = 20 debug auth = 20 I have now rolled back to the old monitor, it works as it should, on the same box etc. But it's the one upgraded from Hammer -> Jewel -> Luminous. Any idea what the issue could be? Thanks. Best regards Anders Olausson
