You should be able to run mkfs.xfs -N /dev/md0 to get that
information.
Can't do it while it's mounted. would xfs_info show the same stuff?
/dev/md3 /r1 xfs
noatime,nodiratime,logbufs=8,logbsize=262144 0 1
Try using the following options and the AS scheduler and let me know
if you still notice any 'hangs'
OK, I've remounted (mount -o remount) with those options.
I've set the strip_cache_size to 8192
I've set the nr_requests back to 128
I've set the schedulers to anticipatory.
Unfortunately problem remains.
I'll try the noop scheduler as I don't think I ever tried that one.

How are you measuring the problem? How can it be reproduced?
Justin.
