Summary fails to detect disk schedulers and queue size

[GoogleCodeExporter]

Interesting.  I am not sure either, to tell the truth I know almost nothing 
about
software raid (the md and dm devices).  Can you check and see if they have 
schedulers
and queue sizes?  The filename glob pattern might need to be broadened.

Can you file a separate issue about the HP Smart array?  Most of my customers 
use LSI
and Adaptec, and I can't even think if I've seen one of the HP controllers..
certainly can't remember who'd have one to sample from :-)

The server is running hardware raid 1 and not software raid. I will file 
another issue 
about the HP controler.

I got the disk schdulers and queue size working.

=======
596c596
<    for disk in /sys/block/*[h,s,c]*d*; do
---
>    for disk in /sys/block/[h,s]d*; do
==========

The result is:

# Disk Schedulers And Queue Size #############################
  cciss!c0d0 | [cfq] 128


I am not sure if it breaks some other things.

I think maybe a different approach is needed, something like

for file in $(find /sys/block -name scheduler); do
  ...
done
