I am new to this sys admin stuff so I would appreciate some info from those in the know. I am trying to do a repair on "/" which is the mount point for an XFS partition /dev/hda4. I have tried doing an "init S" to startup in single user but I am still unable to umount /. I have also tried mounting / as ro. Still can't do an xfs_repair. How can I perform an xfs_repair on /dev/hda4 (i.e. /)? What is the proper procedure for doing this? Here is the ouput from xfs_check -s /dev/hda4 : cormhouse:~ # xfs_check -s /dev/hda4 bad magic number 0x5b44 for inode 79835552 bad magic number 0 for inode 79835553 bad magic number 0 for inode 79835554 bad magic number 0 for inode 79835555 bad magic number 0 for inode 79835556 bad magic number 0 for inode 79835557 bad magic number 0 for inode 79835558 bad magic number 0 for inode 79835559 bad magic number 0 for inode 79835560 bad magic number 0 for inode 79835561 bad magic number 0 for inode 79835562 bad magic number 0 for inode 79835563 bad magic number 0 for inode 79835564 bad magic number 0 for inode 79835565 bad magic number 0 for inode 79835566 bad magic number 0 for inode 79835567 bad magic number 0x5b44 for inode 79835568 bad magic number 0x6c65 for inode 79835569 bad magic number 0x6269 for inode 79835570 bad magic number 0x6f76 for inode 79835571 bad magic number 0 for inode 79835572 bad magic number 0 for inode 79835573 bad magic number 0 for inode 79835574 bad magic number 0 for inode 79835575 bad magic number 0 for inode 79835576 bad magic number 0 for inode 79835577 bad magic number 0 for inode 79835578 bad magic number 0 for inode 79835579 bad magic number 0 for inode 79835580 bad magic number 0 for inode 79835581 bad magic number 0 for inode 79835582 bad magic number 0 for inode 79835583 /usr/sbin/xfs_check: line 63: 2780 Segmentation fault xfs_db$ISFILE -i -p xfs_check -c "check$OPTS" $1 And here is a snippet from xfs_repair -n /dev/hda4 : cormhouse:~ # xfs_repair -n /dev/hda4 Phase 1 - find and verify superblock...
