hi Jeremy - It's in the faq,
Q: My filesystem is ok - but xfs_check or xfs_repair shows errors/won't
run - whats wrong here?
You can not run xfs_repair on a mounted filesystem although support is
available in CVS (08-02-2002) that lets you run xfs_repair with the -n
switch on a read-only mounted filesystem. You must not try to repair a
mounted fs since this will result in dataloss and corruption when
If you have to repair you're filesystem it needs to be unmounted first.
If this is the root (/) filesystem this will mean you have to boot from
a bootable CD and perform the repair on the unmounted filesystem. There
is a link to various bootable floppy/cd projects mentioned in the FAQ
