I mapped an image to a system, and used blockdev to make it readonly. But it
failed.[root@ceph0 mnt]# blockdev --setro /dev/rbd2[root@ceph0 mnt]# blockdev
--getro /dev/rbd20
It's on Centos6.4 with kernel 3.10.6 .Ceph 0.61.8 .
Any idea? _

cat /opt/ceph/current/bin/ceph | head -n 1

if /usr/bin/python is python 3 I have error:
ceph auth get-or-create client.admin
File "/opt/ceph/current/bin/ceph", line 192
print '\n', s, '\n', '=' * len(s)
it is syntax of python2.
I propose change #!/usr/bin/pyt

My ceph cluster is deployed on three nodes.One rbd image was created, mapped to
one of the three nodes, formatted with ext4, and mounted.When rebooting this
node, it hung umouting the file system on the rbd.
My guess about the root cause:When the system shutting
