You might be the victim of this bug: https://bugzilla.redhat.com/show_bug.cgi?id=436383 If so, there's a fix to gfs_fsck to repair the damage. This is associated with this bug record: https://bugzilla.redhat.com/show_bug.cgi?id=440896 While working on that bug, I discovered some kinds of corruption that confuse the gfs_fsck's rindex repair code. That's described in bug: https://bugzilla.redhat.com/show_bug.cgi?id=442271 I don't think any of these fixes are generally available yet, except in patch form; I think they're scheduled for 4.7. The last one, 442271, is only written against RHEL5 at the moment, so I don't have plans to fix it in RHEL4 yet. So here's what I recommend: First, determine for sure if this is the problem by doing something like this: mount the file system gfs_tool rindex /mnt/gfs | grep "4294967292" (there /mnt/gfs is your mount point) umount the file system
That's the problem though, it won't actually let me mount the "disk" because of this problem.
Sounds like my best option is to try and patch the gfs_fsck code in RHE4 and see if it still seg-faults on me...
If that doesn't work, i'm guessing a move to RHEL5 would be the next step, but given the actual value of the data, probably not worth it at this point.
Thanks for the info. I'll let you know how it goes. -- Wes Young Network Security Analyst CIT - University at Buffalo ----------------------------------------------- | my OpenID: | http://tinyurl.com/2zu2d3 | -----------------------------------------------
