 Posted: Sat Mar 13, 2010 5:04 pm Post subject: [SOLVED] How to suppress RAID ? |
 |
|
Hi,
I have a brand new PC, a DELL Studio XPS 8100. It was initially configured in the BIOS with RAID and Windows 7 installed.
I don't want RAID nor Windows, just reinstall Gentoo, with the second disk for home and backups.
I changed BIOS for SATA instead of RAID, and booted Gentoo Live CD 10.1 : gentoo64
With fdisk, I deleted all partitions on sda and sdb and created mines. When it comes to format, I get the error :
| Code: | # mke2fs /dev/sda5
mke2fs 1.41.3 (12-Oct-2008)
/dev/sda5 is apparently in use by the system; will not make a filesystem here!
|
After some research, I rebooted without RAID support : gentoo64 nodmraid
But it is the same.
Then I checked for raid modules and rmmod all of them :
| Code: | livecd ~ # lsmod | grep raid
raid10 20088 0
raid456 47528 0
async_memcpy 2312 1 raid456
async_xor 3720 1 raid456
xor 5400 2 raid456,async_xor
async_tx 3752 3 raid456,async_memcpy,async_xor
raid6_pq 80936 1 raid456
raid1 20440 0
raid0 6876 0
megaraid_sas 36108 0
megaraid_mbox 29352 0
megaraid_mm 9624 1 megaraid_mbox
megaraid 40408 0
aacraid 69728 0
livecd ~ # lsmod | grep dm-mod
livecd ~ # rmmod raid456
livecd ~ # lsmod | grep raid
raid10 20088 0
raid6_pq 80936 0
raid1 20440 0
raid0 6876 0
megaraid_sas 36108 0
megaraid_mbox 29352 0
megaraid_mm 9624 1 megaraid_mbox
megaraid 40408 0
aacraid 69728 0
livecd ~ # rmmod megaraid_sas
livecd ~ # rmmod megaraid_mbox
livecd ~ # rmmod megaraid
livecd ~ # rmmod aacraid
livecd ~ # lsmod | grep raid
raid10 20088 0
raid6_pq 80936 0
raid1 20440 0
raid0 6876 0
megaraid_mm 9624 0
livecd ~ # rmmod raid10
livecd ~ # rmmod raid6_pq
livecd ~ # rmmod raid1
livecd ~ # rmmod raid0
livecd ~ #
livecd ~ # lsmod | grep raid
megaraid_mm 9624 0
livecd ~ # rmmod megaraid_mm
livecd ~ # lsmod | grep raid
livecd ~ #
|
Still the same.
When I run gparted, I have the following messages in the shell : | Code: | livecd ~ # ======================
libparted : 1.8.8
======================

So, the only clue I have is that some deamon checks for devices /dev/dm... | Code: | livecd ~ # ll /dev/dm*
lrwxrwxrwx 1 root root 28 Mar 13 17:30 /dev/dm-0 -> mapper/isw_bdfchjhbah_ARRAY0
lrwxrwxrwx 1 root root 28 Mar 13 17:30 /dev/dm-1 -> mapper/isw_bdfchjhbah_ARRAY1
lrwxrwxrwx 1 root root 30 Mar 13 17:30 /dev/dm-10 -> mapper/isw_bdfchjhbah_ARRAY1p1
lrwxrwxrwx 1 root root 29 Mar 13 17:30 /dev/dm-2 -> mapper/isw_bdfchjhbah_ARRAY02
lrwxrwxrwx 1 root root 29 Mar 13 17:30 /dev/dm-3 -> mapper/isw_bdfchjhbah_ARRAY03
lrwxrwxrwx 1 root root 29 Mar 13 17:30 /dev/dm-4 -> mapper/isw_bdfchjhbah_ARRAY05
lrwxrwxrwx 1 root root 29 Mar 13 17:30 /dev/dm-5 -> mapper/isw_bdfchjhbah_ARRAY11

Just to try.....
Just have a look on processes : | Code: | livecd ~ # ps aux | grep raid

 RTFM myself
This computer is very well documented online. But it got me some time to figure out that. The manual in the box is very light. The downloadable one is 374 pages and explains how to configure RAID0, RAID1, recovery, suppress RAID, and so on.
You can access to Intel RAID utility with <Ctrl i> at boot time - still, no bootable CD shall be in the CD reader. There is also NVIDIA utilities for RAID - so you have the choice, they seem to be equal in functionalities, but I did not dig - accessible with <ctrl n>. |
