Dear All, I got a little problem installing rhel 4u7. I have 4 x 146Gb disk on my server. 2 x 146 with raid 1 and 2 x 146 without raid. When I installing rhel 4u7 a got 3 disk /dev/sda, /dev/sdb and /dev/sdc The problem is, after I finish installing the os, there are another device appears in fdisk -l /dev/sda1, /dev/sdb1, /dev/sdc1, and /dev/dm-0p1. And i can't mount the /dev/sdb1 it said device is busy. I can't mount /dev/dm-0p1 either. I don't have any multipathd install in my system, but why rhel4u7 create that /dev/dm-0 device? Really need advice from you all guys.. BestRegards, -- If knowledge belong to the world, why don't you give me some? ---------------------------------------------- http://dudulz.wordpress.com
