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
