Description Rolf Fokkens 2013-11-29 12:07:38 UTC 
Description of problem:
CephFS mounts are unmounted after the network is stopped dispite the specification of _netdev. This results in a 2 minute delay during shutdown.

Version-Release number of selected component (if applicable):
ceph-0.67.3-2.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Specify a CephFS mount in /etc/fstab including a _netdev option
2. Mount the CephFS mount
3. Note the missing _netdev in /etc/mtab
4. Shutdown the system en note that it takes 2 minutes to unmount CephFS

Actual results:
Long delay during Ceph unmount

Expected results:
No delay during Ceph unmount

This patch fixes the issue

This patch makes mount.ceph store the _netdev option in /etc/mtab but not pass the _netdev option to the kernel.

This makes sure that CephFS mounts are unmounted before the network is stopped.
