In the case of XFS, I've repaired maybe two dozen (or so) corruptions that might be non-trivial (in most of the cases, the filesystem wouldn't even mount before the repair). > fsck.ext2 survives my torture (in some versions). fsck.vfat never > worked for me (likes to segfault), fsck.reiser never worked for me. BTW, I actually have a test filesystem here (an e2image from an actual filesystem I encountered once) that used to cause e2fsck 1.36/1.37 to segfault. Strangely, more ancient versions (like what ships in Red Hat 7.2) were able to repair it without segfaulting. In a few days, once other stuff calms down for me, I need to revisit that and see if the bug still exists with 1.39. -- -Barry K. Nathan
