You can't take that one line of output out of context and then say
it's a hardware problem - that's a generic IO-error-causes-shutdown
message, not an EIO from the storage stack.

The EINVAL error that is reported before this is the cause of the
shutdown, and that is from a corrupted unlinked list. EINVAL
indicates that we are falling off the end of the unlinked list
without finding the inode that we are trying to remove from the
unlinked list. Debug kernels will assert fail at this point.

What causes that problem is still unknown. Nobody has been able to
isolate the reproducer, so progress is slow. If someone can give me
a script that reprodcues it directly on XFS (i.e no gluster), then
it won't take long to find the bug....

Cheers,

Dave.
