[RE]Intel SATA RAID

You are using a very old version (rc9) of dmraid with a newer kernel and there are known problems with that. Try using a newer version (rc13?) you can download here:

Hi all,

I've been asking questions over on the fedora-list, but someone

suggested I try here.

I have a 945P Intel chipset, and have just bought two Seagate 320GB

SATAII disks. They have been jumpered for SATAII peformance and I've

created a RAID 0 container through the Intel BIOS. I've loaded the

drivers in to Windows and can see the container there okay. I haven't

set it to boot from yet, because I want to migrate my existing Linux

setup to it. This is where the fun starts.

To share the RAID 0 container between Linux and Windows I need to use

the Intel driver set.

I will eventually set this as my boot device and use GRUB to boot

between XP, Vista and Linux (FC5).

However, I can't seem to load the container from within my FC5 setup

kernel: 2.6.17-1.2145_FC5smp

dmraid version: 1.0.0.rc9 (2005.09.23) debug

dmraid library version: 1.0.0.rc9 (2005.09.23)

device-mapper version: 4.6.0

> dmraid -s -g

*** Superset

name : isw_bdbbdbcbda

size : 1250284892

stride : 0

type : GROUP

status : ok

subsets: 1

devs : 2

spares : 0

--> Subset

name : isw_bdbbdbcbda_MyRAID0

size : 1250275846

stride : 256

type : stripe

status : ok

subsets: 0

devs : 2

spares : 0

That's cool, makes sense, group, containing MyRAID0 (name in Intel BIOS)

> dmraid -ay

ERROR: dos: reading /dev/mapper/isw_bdbbdbcbda_MyRAID0[No such file or

directory]

huh?! why does it error?

> ls -la /dev/mapper

drwxr-xr-x 2 root root 80 Dec 9 10:42 .

drwxr-xr-x 11 root root 4540 Dec 9 10:42 ..

crw------- 1 root root 10, 63 Dec 9 10:27 control

brw-rw---- 1 root disk 253, 0 Dec 9 10:42 isw_bdbbdbcbda_MyRAID0

> fdisk -l /dev/mapper/isw_bdbbdbcbda_MyRAID0

(nada, zip, zilch, nutin')

So I can see it, but can't access it??

Weird thing, if I boot up FC5 disk 1 and do a linux rescue, I can see it

and list things partitions (made from fdisk in rescue mode)? How is it

mounting it, yet I can't?

Please, any help would be appreciated.

Thanks in advance. Hadders
