RE: XFS internal error XFS_WANT_CORRUPTED_GOTO

Hi Dave,
Thanks for the response.
No I/O errors reported in the message log or on the RAID box.

It's an Infortrend SATA RAID5 array, with a fibre channel connection to
the server.
The filesystem is build on an LVM volume.
Kernel is 2.6.13-15-smp running on an x86_64 dual CPU Xeon server with
hyper-threading enabled.
The most significant feature of the load is that it is part of an HPC
cluster, and has a large number of nodes NFS mounting the filesystem
across Gigabit ethernet.

I did notice that in the first incident, a user had a directory with
700000 files in it, and xfs_repair found fault with that directory. The
user has revised their workflow since and removed the files.
Very difficult to spot common traits in the workload between the 2
incidents.

Cheers,
Simon
