We observed this message this morning on the node. Is it possible a related issue?Â

Hi Brain,

Is this the file which you need ?

https://cloud.swiftstack.com/v1/AUTH_hugo/public/xfs.ko

$> modinfo xfs

filename: /lib/modules/2.6.32-504.23.4.el6.x86_64/kernel/fs/xfs/xfs.ko 
license: GPL 
description: SGI XFS with ACLs, security attributes, large block/inode numbers, no debug enabled

Thanks, I can actually load that up now. Note that we'll probably need
the modules and whatnot (xfs.ko) also to be able to look at any XFS
bits. It might be easiest to just tar up and compress whatever directory
structure has the debug-enabled vmlinux and all the kernel modules.
Thanks.

Brian
