Finally got the results of xfs_repair -n on all disks for this server. There's no any warning or error from my observation.
Thanks // Hugo

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

Is this the file which you need ?

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.
