Summary

0002484: Incorrect device path with mdev when name contains '!'

Description

I'm using busybox for my Linux installer. I've encountered small problem today. On machine with DAC960 raid controller path to device created by mdev is incorrect. It should be /dev/rd/c0d0 and mdev created /dev/rd!c0d0. Device work ok, but such path is in my case problematic as I've to hack it with in freshly installed system to replace all '!' with '/'. Is it possible to have mdev creating proper paths? I think same problem may occur with otherraid controllers like cciss or cpqarray.

Any chances for patch with fix? Or at least some hints where to look in sources to fix :)

I'm currently using busybox 1.8.2.

(0005784) hawq 03-15-08 06:55	According to kernel doc cciss and cpqarray will suffer from same problem. /sys entries examples are: For DAC960 controllers: rd!c0d0 rd!c0d0p1 For Compaq Intelligent Drive Array (cpqarray): ida!c0d0 ida!c0d0p1 For Compaq Next Generation Drive Array (cciss): cciss!c0d0 cciss!c0d0p1 and so on. Wouldn't simple string replace (all ! with /) be enough if contents of DEVPATH matches above patterns?

(0005804) vapier 03-20-08 23:50	just add an mdev.conf rule for it ... maybe something like: rd!.* 0:0 660 >rd/
