updatedb triggers XFS internal error

[Evan Fraser]

Hello,
I'm having a problem with one of my linux servers. whenever updatedb is 
run, the following errors occur in the system log.

Its a dual opteron system running Fedora Core 4 and running the fedora 
packaged 2.6.12-1.1456_FC4smp kernel.  The filesystem in question is on 
a md stripe raid running across an  Infortrend 1.4TB hardware SCSI raid.

The output from xfs_info is:

meta-data=/user_data             isize=256    agcount=32, 
agsize=11180624 blks
         =                       sectsz=512
data     =                       bsize=4096   blocks=357779520, imaxpct=25
         =                       sunit=16     swidth=32 blks, unwritten=1
naming   =version 2              bsize=4096
log      =internal               bsize=4096   blocks=32768, version=1
         =                       sectsz=512   sunit=0 blks
realtime =none                   extsz=131072 blocks=0, rtextents=0


Any help will be gratefully received!

Cheers, Evan.

This indicates bad metadata magic read from disk.  You'll probably want 
to run xfs_repair; you can run it with -n to see what it *would* do 
first, to get an idea of how drastic the repair might be.  Repairing 
1.4T won't probably be lots of fun, but you've got corruption in there 
somewhere...
