Description David Mudrich 2011-02-18 17:19:15 UTC 
Description of problem:

The netfs initscript does not mount _netdev devices, which do not contain one of nfs4,cifs,ncpfs,gfs.

Long time ago, there has been a patch to restrict mount -a to:
mount -a -t nonfs,nfs4,cifs,ncpfs,gfs

This leads to a regression, both fstab lines will not be mounted:
/dev/md_d5012		/home/STORAGE		xfs	_netdev		0 0
/dev/etherd/e0.3	/home/BACKUP		ext3	_netdev		0 0

Version-Release number of selected component (if applicable):
9.20.1-1.fc14

How reproducible:
Always, as above.
  
Actual results:
_netdev devices not mounted

Expected results:
_netdev devices mounted

Additional info:
Added the following line before the existing mount command:

action $"Mounting network blockdevices: " mount -a -O _netdev -t nonfs,nonfs4,nocifs,noncpfs,nogfs

Forgot to mention: the added line is a patch to make it work.
Comment 2 Bill Nottingham 2011-02-21 17:20:35 UTC 
That shouldn't be needed; something else must be wrong. If you run that mount command (without the -O ...), what does it try to do?
Comment 3 David Mudrich 2011-03-03 19:58:19 UTC 
I haven't tested, but I assume a regression to bug #4868 (1999).

ie.:

until 1999, which included not-yet-mounted _netdev devices:
mount -a

from 1999, after Bugfix #4868, _netdev was forgotten:
mount -a -t nonfs,smbfs,ncpfs

has been expanded to, still no _netdev:
mount -a -t nonfs,nfs4,cifs,ncpfs,gfs


_netdev is needed if you want to mount a filesystem other than nfs4,cifs,ncpfs or gfs lately, eg. on AoE devices.
If we do a simple mount -a here, someone needs to examine if the old bug #4868 still occurs.
Comment 4 Bill Nottingham 2011-03-03 20:31:56 UTC 
_netdev *should not be needed*. I believe you misunderstand how -t works.

What that statement is:

mount all filesystems except nfs, nfs4, cifs, ncpfs, and gifs.

The 'no' applies to all of the listed filesystems.
Comment 5 David Mudrich 2011-03-04 16:33:41 UTC 
OK, I misunderstood that.

That is, all other outstanding mounts get done, including _netdev.

Thanks.
