Re: ceph-mgr fails to restart after upgrade to mimic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

I can't think of why the upgrade would have broken your keys, but have you verified that the mons still have the correct mgr keys configured? 'ceph auth ls' should list an mgr.<host> key for each mgr with a key matching the contents of /var/lib/ceph/mgr/<cluster>-<host>/keyring on the mgr host and some caps that should minimally include '[mon] allow profile mgr' and '[osd] allow *' I would think.

Again, it seems unlikely that this would have broken with the upgrade if it had been working previously, but if you're seeing auth errors it might be something to check out.

Greetings,

I'm upgrading my cluster from luminous to mimic. I've upgraded my monitors and am attempting to upgrade the mgrs. Unfortunately, after an upgrade the mgr daemon exits immediately with error code 1.

I've tried running ceph-mgr in debug mode to try to see what's happening but the output (below) is a bit cryptic for me. It looks like authentication might be failing but it was working prior to the upgrade.

I do have "auth supported = cephx" in the global section of ceph.conf.

What do I need to do to fix this?

Thanks.
