Mount hardware RAID0 [SOLVED]

My question is: how to mount  hardware RAID 0 ? i have the newest version of arch linux. Raid is on nvidia chipset. after searching a little i found out that it is not the way in "software raid" on wiki. I need to keep it hardware RAID because there is already installed windows. so all i want to do is just mount ma windows partitions in linux.

Thanks for help

P.S
i'm new to the arch - but i already think this is great distro

Re: Mount hardware RAID0 [SOLVED]

Your nVidia RAID-set is not hardware RAID. It's firmware (or software) RAID because your RAID-controller lets your CPU do all the RAID-calculations.

You need to find out which module is appropriate for nVidia RAID. After loading it, the module should detect your array and create a device for it (e.g. /dev/nvidia/raid0 or something). Then you can list the partitions on your array using "fdisk -l /dev/nvidia/raid0" and see which one is your Windows partition. Finally you can mount the partition using for instance "mount /dev/nvidia/raid0p1 /mnt/windows".

Re: Mount hardware RAID0 [SOLVED]

Check the output of dmesg. Does it mention anything concerning the disks? You may still have to create the actual device, for instance

mdadm --assemble /dev/md0 /dev/sda /dev/sdb

Re: Mount hardware RAID0 [SOLVED]

my two hd is sdb and sdc so i try this:

root@badboy ~]# mdadm --assemble /dev/md0 /dev/sdb /dev/sdc
mdadm: no recogniseable superblock on /dev/sdb
mdadm: /dev/sdb has no superblock - assembly aborted

have no idea what's next

ah end also:

dmesg | tail
NTFS-fs error (device sdc1): ntfs_fill_super(): Failed to load essential metadata.
md: md0 stopped.
md: md0 stopped.
md: md0 stopped.
md: md0 stopped.
md: md127 stopped.
md: md127 stopped.
md: md0 stopped.
md: md0 stopped.
md: md0 stopped.

Re: Mount hardware RAID0 [SOLVED]

dmraid -b

to list the block devices. You need to find out what devices your RAID consists off. It's also possible Linux can't handle your array because you're probably using the onboard config (RAID BIOS) rather than Linux software RAID.
