OK I am in some trouble now and would love some help! After updating none of the OSDs on the node will come back up:

I did some searching and saw that the issue is that the disks aren't mounting... My question is how can I mount them correctly again (note sdb and sdc are ssd for cache)? I am not sure which disk maps to ceph-osd@0 and so on. Also, can I add them to /etc/fstab to work around?
Cheers,
Mike

Hello,I would like to install OS updates on the ceph cluster and activate a second 10gb port on the OSD nodes, so I wanted to verify the correct steps to perform maintenance on the cluster. We are only using rbd to back our xenserver vm's at this point, and our cluster consists of 3 OSD nodes, 3 Mon nodes and 1 admin node... So would this be the correct steps:1. Shut down VM's?2. run "ceph osd set noout" on admin node3. install updates on each monitoring node and reboot one at a time.4. install updates on OSD nodes and activate second 10gb port, reboot one OSD node at a time5. once all nodes back up, run "ceph osd unset noout"6. bring VM's back onlineDoes this sound correct?Cheers,Mike
