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 How reproducible: Have installed on another DL380 same results, Steps to Reproduce: 1. 2. 3.

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 :-(. Anyway this entry is a duplicate, we'll continue tracking it there.
