I was loosing my KDE settings bit by bit with every reboot during the bisection. First my window-rules disappeared, then my desktop background changed to default, then my taskbar moved from top to the bottom, etc. In the end I had to restore all my .files from backup. And please note that xfs_repair unlinked the inodes _after_ the filesystem has been mounted and unmounted normally. -- Markus _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
