software raid issue

linuxgeek2940 · 05-02-2007, 08:22 AM

Hello,
I have a recently set up Debian Etch (4.0) system, with a software raid to combine my five smaller SCSI disks to make them a usable size. This was all set up during the install process, and I had hoped to mount my /home directory on them, but I am unable to access them from within the system. When I boot off of a live CD, such as Knoppix, it notices that the disks are part of a software raid setup, but I am unable to access the raid through Etch.

What have you actually done to try to access the new array?

I have tried typing in /dev/sda1 through /dev/sde1 in Konquer. I have also tried going to the disks to the disks display panel in GNOME. Any other suggestions? I think I formated the disks during the install, but I am not entirely sure, now that I think about it.

If this is an mdadm array, then it should be /dev/md* where * is 0, 1, 2, etc. If it's a dmraid (FakeRaid configured by the BIOS) then it will be /dev/mapper/xxx_yyyyyyyy*. xxx would be something like "pdc", yyyyyyy would be some random alphanumeric number, and * would be blank for the array itself, and 1, 2, 3, etc for the partitions on the array. Since you said it was configured by the installer, it should be /dev/md*. You do not want to touch the disks that comprise the array, such as /dev/sda*, /dev/hda*, or whatever.

Thank you, I will try that.
