Ceph monitor won't start after Ubuntu update
Hello Ceph-users, I've upgraded my Ubuntu server from 18.04.5 LTS to Ubuntu 20.04.2 LTS via 'do-release-upgrade', during that process ceph packages were upgraded from Luminous to Octopus and now ceph-mon daemon(I have only one) won't start, log error is: "2021-06-15T20:23:41.843+0000 7fbb55e9b540 -1 mon.target@-1(probing) e2 current monmap has recorded min_mon_release 12 (luminous) is >2 releases older than installed 15 (octopus); you can only upgrade 2 releases at a time you should first upgrade to 13 (mimic) or 14 (nautilus) stopping." Is there any way to get cluster running or at least get data from OSDs? Will appreciate any help. Thank you -- Best regards, Petr

Ceph is not supported +3 releases upgrade, only +1 or +2. I suggest to install Nautilus packages and start cluster again k

Ceph is not supported +3 releases upgrade, only +1 or +2. Yep, already got that.
I suggest to install Nautilus packages and start cluster again I would like to, but there is no Nautilus packages for Ubuntu 20(focal).

You can just use your mondb data in another (bionic?) Ubuntu to make a upgrade. Then return upgraded data to your focal Ubuntu. Cheers, k Sent from my iPhone
