Re: OSDs stuck in booting state on CentOS 7.2.1511 and ceph infernalis 9.2.0

Bryan,

Once the rest of the cluster was updated to v0.94.5 it now appears the one host running infernalis v9.2.0 OSDs are booting.

Bryan,

I rebooted another host which wasn't updated to CentOS 7.2 and those OSDs also failed to come out of booting state. I thought I'd restarted each OSD host after upgrading them to infernalis but I must have been mistaken and after running ceph tell osd.* version I saw we were on a mix of v0.94.1, v0.94.2, v0.94.4, and v0.94.5. I've downgraded the two hosts we were having problems with to hammer v0.94.5 and once the cluster is happy again we will try upgrading again.

Good luck.

I ran into a similar problem while in the middle of upgrading from Hammer (0.94.5) to Infernalis (9.2.0).  I decided to try rebuilding one of the OSDs by using 'ceph-disk prepare /dev/sdb' and it never comes up:

I'm running this on Ubuntu 14.04.3 with the linux-image-generic-lts-wily kernel (4.2.0-21.25~14.04.1).

Are you running a mixed cluster right now too?  For example this is my cluster right now:

root@b1:~# ceph tell osd.* version | grep version | uniq -c
osd.10: Error ENXIO: problem getting command descriptions from osd.10

Subject: OSDs stuck in booting state on CentOS 7.2.1511 and ceph infernalis 9.2.0

We've been operating a cluster relatively incident free since 0.86. On Monday I did a yum update on one node, ceph00, and after rebooting we're seeing every OSD stuck in 'booting' state. I've tried removing all of the OSDs and recreating them with ceph-deploy (ceph-disk required modification to use partx -a rather than partprobe) but we see the same status. I'm not sure how to troubleshoot this further. Our OSDs on this host are now running as the ceph user which may be related to the issue as the other three hosts are running as root (although I followed the steps listed to upgrade from hammer to infernalis and did chown -R ceph:ceph /var/lib/ceph on each node).
