fsck.xfs on ro mounted disks

[Valentijn Sessink <valentyn+xfs@xxxxxxxxxxxxxxxxxxxx>]

Hello list,

Is there any chance that the XFS check and repair utilities will start
working on a (read-only) mounted disk someday? xfs_check and xfs_repair now
complain that the disk is mounted and refuse to do anything. This makes
using XFS as root fs a bit unpleasant, as a reboot in single user mode or
even in "emergency" mode (running /bin/sh instead of init) will not help to
fix any file system problems.

Is there a way to force xfs_repair to work on a read only fs?

Best regards,

Valentijn
