[linux-lvm] could not mount LVM2 read only snapshot

["Michael Jiang" <xiaominj gmail com>]

I use 'lvcreate -p r' to create a read only snapshot. got following error message when I try to mount it

"mount: wrong fs type, bad option, bad superblock on 
/dev/VolGroup00/snap,
      or too many mounted file systems"

If I do not use '-p r' and mount -r, then it works fine.

kernel 2.6.9-42.ELsmp
# lvm version
  LVM version:     2.02.06 (2006-05-12)
  Library version: 1.02.07 (2006-05-11)
  Driver version:  4.5.0

Anyone had the same problem before?

Thanks

Michael
