Hello lists :

Does anyone knows , How to monitor Software RAID disk I/O ????

i have a Software RAID5 device named "/dev/md0" , i've tried to use "iostat" to monitor /dev/md0 I/O status ...

But, it's seems doesn't work !!!
===========================
fileserver:/etc/rc.boot# iostat -x /dev/md0
Linux 2.4.20-xfs (fileserver) 07/10/03
avg-cpu: %user %nice %sys %idle
1.18 0.01 1.05 97.76
Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util
===========================


i've tried to use "mdadm"also, but same as "iostat" result (no more I/O output!!!)

Does anyone knows , How to monitor Software RAID disk I/O ????

Thanks.
