Even the root ro to rw remount swicheroo is antiquated. Not ext3/4, XFS, nor Btrfs want you to run an fsck on an ro mounted volume. Both e2fsck and xfs_repair use strong wording saying not to do it, to the point I think it's crusty weirdness to keep the code allowing things like "dangerous" mode repair. The btrfs check tool on the other hand will neither check nor repair a mounted volume - it's actually a nearly last resort there. Usually normal mount fixes things, and if not the first option is to use -o recovery mount option. -- Chris Murphy _______________________________________________ CentOS mailing list [email protected] http://lists.centos.org/mailman/listinfo/centos
