[root_at_pcp005034pcs fio]# ./fio seagate-aio-read.job

found fio- trying to test perfomance of seagate FC disks.
trying to see if they actually do 90-40 MB/s
getting only 73 MB/s so far even with aio and queue depth =4 on ext3 formatted disks

q1) how do I test just RAW disk?

2) the program faults if I add the line to the job


see attached job. which fails

[root_at_pcp005034pcs fio]# cat .git/HEAD
