Can't do it while it's mounted. would xfs_info show the same stuff?

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.
