This patch

bumps DK_MAX_MAJOR to 111 to fix that. This has been a

common complaint

by customers wishing to gather info about cciss devices.
Please consider this for inclusion. Applies to 2.4.28-pre3.

Thanks,

The answer to this is to use the latest sysstat tools. the latest version of iostat, sar, etc draw information out of /proc/partitions rather than out of /proc/stat. Or are you using some other home rolled tool in this case?

Neil


It's customers that are doing this. I think some of them are using their own tools. Others are probably using whatever comes on their distro.

mikem

They should probably upgrade their tools, be they from the distro or their own (It was my understanding that /proc/stat was depricated and going to be removed in the not-to-distant future).
