Hi
I'm in a bit of a panic :-(
Recently we started attempting to configure a radosgw to our ceph
cluster, which was until now only doing cephfs (and rbd wss working as
well). We were messing about with ceph-ansible, as this was how we
originally installed the cluster. Anyway, it installed nautilus 14.2.18
on the radosgw and I though it would be good to pull up the rest of the
cluster to that level as well using our tried and tested ceph upgrade
script (it basically does an update of all ceph nodes one by one and
checks whether ceph is ok again before doing the next)
After the 3rd mon/mgr was done, all pg's were unavailable :-(
obviously, the script is not continuing, but ceph is also broken now...
The message deceptively is: HEALTH_WARN Reduced data availability: 5568
pgs inactive
That's all PGs!
I tried as a desperate measure to upgrade one ceph OSD node, but that
broke as well, the osd service on that node gets an interrupt from the
kernel....
the versions are now like:
20:29 [root@cephmon1 ~]# ceph versions
{
"mon": {
"ceph version 14.2.18
(befbc92f3c11eedd8626487211d200c0b44786d9) nautilus (stable)": 3

"mgr": {
"ceph version 14.2.18

},
"osd": {

},
"mds": {
"ceph version 14.2.15

},
"overall": {
"ceph version 14.2.15

"ceph version 14.2.18

}
}
12 OSDs are down
