xfs_check refuses to work on readonly fs

["CN" <cnliou9@xxxxxxxxxxx>]

Hi!

# init 1
# mount -o ro,remount /
# mount
/dev/hda1 on / type xfs (rw)
# xfs_check /dev/hda1
xfs_check: /dev/hda1 contains a mounted and writable filesystem

xfs_check/xfs_repair are willing to work only when I boot from a disk
and check/repair the other unmounted disk.

Why "mount" shows (rw) instead of (ro) even "mount -o ro,remount /" is
issued?

fsck.ext3 works fine given the same sequence of commands for ext3
mounted file system. Did I miss anything with XFS?

Thank you in advance!

CN
