Optimal Setup Question

[Chris Penney <cpenney@xxxxxxxxx>]

I am about to setup an NFS servers using SuSE Enterprise 9 w/ SP1-RC5.
 The hardware is a dual cpu P4, 2GB RAM, gigabit ehternet, and dual
qlogic hbas.  It is being presented four 1TB luns from an LSI disk
array, each is raid 8+1 with a 64k segment size (so one stripe is 512k
of data).  The luns will be used for an XFS file system that will be
NFS exported.  The i/o pattern is largely writes (80%).

I intend to use lvm2 to make a 4TB device via the command "lvcreate
-i4 -I512 -L<max> -ntestvol testdg" unless that is flawed.

I want to use XFS unless there is a good reason not to.  I'm looking
for optimal mkfs.xfs options as well as mount options.  In particular
any settings I may need to make with regard to having four luns and a
512k stripe size.

Thanks,

   Chris
