Hello fellow ceph users,
I ran into a major issue were two KVM hosts will not start due to issues with my Ceph cluster.
Here are some details:
Running ceph version 0.87. There are 10 hosts with 6 drives each for 60 OSDs.

Also, if I run the following cmd, it seems to just hang.
rbd -p rbd-b info vm-50193-disk-1 ß hangs until I do CTRL-c…
Any help would be greatly appreciated!
