FYI, This is unrelated to my previous post a few minutes ago...
When trying to mount the ceph file system, I typed the command:
[EMAIL PROTECTED] mnt]# mount -t ceph 10.0.1.14:/ cephfs/
Of course, I forgot to initialize my MDS and OSD nodes, so really there
was nothing to mount.
However, it did not exit gracefully. Below is some kernel output that
you might find useful.
