Yes, thats even worse. I found I can just put random things in there
when doing a mount -o remount, and it will just show up.
pyre:~# mount -o remount,bobsyouruncle /shared
pyre:~# mount | grep shared
/dev/mapper/vg0-shared on /shared type xfs (rw,sunit=128,swidth=256,bobsyouruncle)
Thats on 2.6.32. No error in dmesg output either.
It doesnt accept random nonexistent options when mounting, only when
remounting.
moupyre:~# mount -o bobsyouruncle /shared
mount: wrong fs type, bad option, bad superblock on
/dev/mapper/vg0-shared,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
pyre:~# dmesg | tail -n1
[441854.007959] XFS: unknown mount option [bobsyouruncle].
