Description of problem:
when running a grep -i "diskio" /proc/stat, returns the "diskio" with
no trailing data (blank)
when running iostat -x, not all the disks are shown
when running df -k, all of the disks are shown
(all of the disks are in the /etc/fstab
Version-Release number of selected component (if applicable):
current version of cciss driver=cpq_cciss_RedHatAS21-2.4.44-1
Have installed on another DL380 same results,
Steps to Reproduce:
See Red Hat Service requests 273214 and 274305
This is on a Compaq DL380 with the standard RAID controller. There
may or may not be data shown upon installation. Any activity, such as
removing one of the two drives (RAID 1 config) and replacing it seems
to trigger the problem -- if it isn't there on installation already.
Upgrading to RHEL ES 3.0 doesn't seem to make any difference.
For me this behaviour seems to stem from the fact that both cciss and
cpqarray drivers aren't implemented as SCSI devices but as their own
block devices. Somehow these block devices don't get taken into
account for /proc/stat.
I don't know why Compaq/HP did the implementation that way, this has
caused confusion and problems in many other cases as well :-(.
