Hi Sam, The daemons restart (for *some* releases) because of this: https://tracker.ceph.com/issues/21672 In short, if the selinux module changes, and if you have selinux enabled, then midway through yum update, there will be a systemctl restart ceph.target issued. For the rest -- I think you should focus on getting the PGs all active+clean as soon as possible, because the degraded and remapped states are what leads to mon / osdmap growth. This kind of scenario is why we wrote this tool: https://github.com/cernceph/ceph-scripts/blob/master/tools/upmap/upmap-rema… It will use pg-upmap-items to force the PGs to the OSDs where they are currently residing. But there is some clarification needed before you go ahead with that. Could you share `ceph status`, `ceph health detail`?

So, we started the mons and mgr up again, and here's the relevant logs, including also ceph versions. We've also turned off all of the firewalls on all of the nodes so we know that there can't be network issues [and, indeed, all of our management of the OSDs happens via logins from the service nodes

hi Dan: So, unsetting nodown results in... almost all of the OSDs being marked down. (231 down out of 328). Checking the actual OSD services, most of them were actually up and active on the nodes, even when the mons had marked them down. (On a few nodes, the down services corresponded to OSDs that had been flapping - but increasing osd_max_markdown locally to keep them up despite the previous flapping, and restarting the services... didn't help.) In fact, starting up the few OSD services which had actually stopped, resulted in a different set of OSDs being marked down, and some others coming up. We currently have a sort of "rolling OSD outness" passing through the cluster - there's always ~230 OSDs marked down now, but which ones those are changes (we've had everything from 1 HOST down to 4 HOSTS down over the past 14 minutes as things fluctuate.

Hm, yes it does [and I was wondering why loopbacks were showing up suddenly in the logs]. This wasn't happening with 14.2.16 so what's changed about how we specify stuff? This might correlate with the other person on the IRC list who has problems with 14.2.18 and their OSDs deciding they don't work sometimes until they forcibly restart their network links...

Hi Dan: Aha - I think the first commit is probably it - before that commit, the fact that lo is highest in the interfaces enumeration didn't matter for us [since it would always be skipped]. This actually almost certainly also is associated with that other site with a similar problem (OSDs drop out until you restart the network interface), since I imagine that would reorder the interface list. Playing with our public and cluster bind address explicitly does seem to help, so we'll iterate on that and get to a suitable ceph.conf. Thanks for the help [and it was the network all along]!
