We replaced the drive and rebuild the array.
Why rebuild the array when you have hardware raid5. You should be able to boot the degraded array and work from there.
I booted up with a CD that I created a while a go with 2.4.19-pre9-20020604 and mounted a
I understand that the machine did not boot anymore after the crash? Can it be that the drive had write caching which made it fail horribly in the end and crashed the machine?
nfs root partition with all the xfs tools on it. We ran xfs_repair (version 2.2.1) on the root partition of the raid array. A lot of the files have the dreaded zero problem, but apart from that it is mountable and usable.
The zero problem is fixed in the 1.1 release and should be no longer present. That was one of _the_ important fixes in the 1.1 release.
fatal error -- can't read block 0 for directory inode 2097749 </xfs_repair>
Do you have the ability to fetch the current CVS tools and see if that works better?
The output of xfs_repair is large about 300k bzip2'ed. It would be best if interested parties download it.
Would it be possible to make xfs_repair use a lot less memory ? My guess is that the filesystem got it's final blow by xfs_repair exiting prematurely.
Quite possible. There have been some fixes for xfs_repair and the memory usage but I don't think every single case is handled for low memory use.
Did the disk have a lot of small files (in the order of a million files in one directory or so?
