Now we know how to do it I think, but is it > worth the effort. With a filesystem that is compartmentalized and checksums metadata, I believe that an online fsck is absolutely worth having. Instead of the filesystem resorting to mounting the whole volume read-only on certain errors, part of the filesystem can be offlined while an fsck runs. This could even be done automatically in many situations. -- All rights reversed.
