Thanks for the information. I checked iostat on one of my older servers running off CentOS 5.0 (2.6.18-53.1.21.el5xen) which was also running md raid 1 and it also confirmed that the md raid 1 was getting reads from both member devices.So long as you generate disk access through a file system and not hdparm.
Would running two CP command to copy 2 different set of files to two
different targets suffice as a basic two thread test?
Like I said: iostat
Is there a way to monitor actual disk transfers from command line without
having to do manual timing?
Although looking at it now, I think I really screwed up that installation, being my first, I had md running on top of LVM PV *slap forehead*
