auto-mount broken - Ubuntu 14.04
 

Hello. I'm having troubles with mounting an iSCSI connection on startup. When auto mount on startup was working, the mount command showed:
/dev/sdc on /mnt/san-1 type ext3 (rw,bsdgroups,_netdev)

Now when I run mount it shows:
/dev/sdc on /mnt/san-1 type ext3 (rw)

How to get bsdgroups and _netdev back? Do I include them in the manual mount command? If so please show an example (we're in the newbie forum after all :))

It is in /etc/fstab as (I removed the UUID characters):

UUID=<long string of characters> /mnt/san-1 ext3 defaults,bsdgroups,_netdev,umask=0000 0 0

When I run blkid command I see at the end: /dev/sdc: UUID="<same matching characters as in fstab>" TYPE="ext3"

When I reboot, the server hangs at:

INFO: task umount:3987 blocked for more than 120 seconds.
Not tainted 3.13.0-36-generic #63-Ubuntu
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message

I force reboot and the filesystem doesn't mount automatically. From what I've read it might be because _netdev needs to be present for the networking to start so it can mount the iscsi connection. But if it's in fstab why isn't it... applying? Can anyone shed some light on what's going on and what to do about it?

I should also mention when I ssh in as root I see, but this was later on after I noticed the automount broken:

/dev/sdc should be checked for errors

and below that (not sure if this is related) it says

*** System restart required ***

Thanks!
