[rhelv6-beta-list] dm-XX devices in mtab

[Furtmueller, Bernhard]

Hi List,

When I started playing with gfs2 I observed following issue, which
I find really _very_ at least annoying:

Mounting a gfs2 filesystem ... 
~# mount /dev/vg_scratch/lv_scratch /scratch

Actual result:
~# mount -t gfs2
/dev/dm-16 on /scratch type gfs2 (rw,seclabel,relatime,hostdata=jid=0)

~# grep scratch /proc/mounts
/dev/dm-16 /scratch gfs2 rw,seclabel,relatime,hostdata=jid=0 0 0

Expected restult:
~# mount -t gfs2
/dev/vg_scratch/lv_scratch on /scratch type gfs2

What do you think about these mounts in cluster?
