Rob,
Sorry to be the johnny-come-lately to this discussion.
Hi everyone,
I am attempting to use XFS on a number of RHEL ES 4 servers. I need help.
I have downloaded the patch, installed the xfsprogs and was able to use
mkfs.xfs to format a partition. When trying to mount the filesystem, it
tells me the kernel does not support XFS. I know that I need to recompile
the kernel to get this thing working, but I have no idea on how to do
this. I am wanting to use XFS to create a 120 TB filesystem (growable up
to 300 TB). XFS is my only option if I want a filesystem this large, is
this correct? Thanks in advance for your help.

You realize, of course, that XFS isn't cXFS, and that if you create a
single 120TB volume only *one* machine will be able to mount that volume
read-write. I'm not even sure if another system could mount that volume
as read-only in parallel.
If anyone has that kind of data, we (Fermilab) do, so I'd be interested
in your (public) findings. I think the latest count of XFS disks here
at Fermi is in the 800-900TB range (and growing), all of it white-box
NAS, and a lot of it used as dCache pool nodes (http://www.dcache.org).
Cheers,
Dan
PS, I'm not currently subscribed to linux-xfs, so please cc me directly.
Thanks.
