HOWTO - Discovering and using existing sata raid (eg sil3112)

[cypher35]

Thanks dude!

The only problem i had was the current dmraid package requiring some sortof "selinux" library. I simply downloaded an earlier release and it worked like a charm.

hey
everything seems to work OK but when i run dmraid -ay -v I get
"gavin@Apollo:~$ sudo dmraid -ay -v
ERROR: hpt37x: wrong # of devices in RAID set "hpt37x_eccadiicdi" [1/2] on /dev/hde
ERROR: removing inconsistent RAID set "hpt37x_eccadiicdi"
No Software RAID sets"

So i run
"gavin@Apollo:~$ sudo dmraid -r
/dev/hde: hpt37x, "hpt37x_eccadiicdi", stripe, ok, 156355520 sectors, data@ 0"

So I guess it's just not seeing /dev/hdf, which is there but in fdisk- l
"Disk /dev/hde: 80.0 GB, 80054059008 bytes
255 heads, 63 sectors/track, 9732 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hde1 1 19465 156352581 7 HPFS/NTFS

Disk /dev/hdf: 80.0 GB, 80054059008 bytes
16 heads, 63 sectors/track, 155114 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

Disk /dev/hdf doesn't contain a valid partition table"

however I wasn't aware hdf needed a valid partition table, It works in windows xp
is this a product of it being NTFS formatted?

any ideas? thanks

Hi guys,

This is my second attemp to mount my RAID-0 2 SATAS disks on Sil3112 (NF7). On Hoary version I gave up after a while...

Now I just installed Breezy and managed to get much further but instead of using device mapper from Redhat I used the one from Debian found on this link

Now in my /dev/mapper/ I see my partition listed....

Now the problem is when I try the command mount -t <fs type> -o users,owner,ro,umask=000 /dev/mapper/<your partiton name> /<your mount dir> I get the message already mount or busy....

I don't know where else could be mount...I search around but don't see it no where...

Anyone has an idea ?

Thank you


Edit: Got it work....I have to mount the 2 others sil_ and not the first one.....Thanx for the tutorial

Cracking guide! helped me no end!

This is *NOT* for people with new, blank hdds. For you it is much easier IMHO to set them up using linux software raid, i believe that there is a howto on this forum already for that.

Where is this how-to?

searching for "linux software raid" doesn't produce anything that shows a newbie how to plug their ata drive into the raid plug on their motherboard and get the system to show the hdisk as /dev/sdx or whatever.

(having a superadvanced how-to is nice too of course)

Thanks!

Hi,

First of all many thanks for a great thread, it's been on great use to me.

Secondly I am sorry to bump it again but I am still having some issues and hoping someone out there can help me.

I have an ASUS motherboard which has an onboard SiI 3512, I have 2 SATA drives which I have striped. I'm running Windows XP with 2 NTFS partitions, which show in Windows as a C and D Drive. I also have some free space in which I want to install Linux.

From lspci I get

0000:01:0d.0 RAID bus controller: Silicon Image, Inc. (formerly CMD Technology Inc) SiI 3512 [SATALink/SATARaid] Serial ATA Controller (rev 01)

After following the instructions in the post when I ls /dev/mapper I see

casper-cow control sil_afaedfbjcfcc2
casper-snapshot sil_afaedfbjcfcc sil_afaedfbjcfcc5

So far so good...

When I try and mount sil_afaedfbjcfcc2 it mounts no problem and I see the contents of the C Drive.

When mounting sil_afaedfbjcfcc5 I would expect to see the D Drive. I don't, I see the contents of the C drive. Even when mounting them one at a time.

fdisk -l gives...

Device Boot Start End Blocks Id System
/dev/sda1 2 2611 20964825 f W95 Ext'd (LBA)
/dev/sda2 * 2612 13054 83883397+ 7 HPFS/NTFS
/dev/sda5 ? 121635 248474 1018833296 54 OnTrackDM6

Is anyone able to assist me in mounting the contents of my D drive?

Thanks,

Andrew

5) now everything is installed. You just need to make dmraid load on startup and set up the drive mounting.
I didnt make mine load on startup, as i do not need to access my raid drives all that often. So i made a little script to mount them when i need them in my home directory.
Heres how:

You need to find your device name.
ls /dev/mapper/

There will be a few entries that look long and confusing. They are actually just the partitions of your raid drives, prefixed with a complex name. mine looks like
sil_0309402025011
sil_0309402025011_p1
sil_0309402025011_p5

you need to note these down.

Hi I realize this thread is several years old by now but I just installed ubuntu and am trying to configure my ntfs raid-0 partition and mount it. As the post states it is for a sil3112a controller, which I have as part of my Abit NF7-S motherboard. I have installed the kernel source, downloaded device-mapper.1.02.17 and dmraid1.0.0.rc13 and installed them both, what i think is successfully. As the guide said I skipped step 2 since I am on Ubuntu Edgy 6.10. Until the step i have quoted above it has seemed to all go fine. But when I do

ls /dev/mapper

it gives me
ls: /dev/mapper: No such file or directory

Could my drive be in some other location?

This is a copy of my fdisk -l
These are the 2 partitions that is my NTFS Raid-0 partition

Disk /dev/sdb: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table

Disk /dev/sdc: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1   *           1       39858   320159353+   7  HPFS/NTFS

any help would be greatly appreciated, I think I am very close. Thanks

Hi

Have you run 'dmraid -ay'?

This starts the raid discovery and after this the files have appeared in /dev/mapper for me.

Hi everybody!
I have a little problem... May be anybody of you have ever encountered it?
When I type dmraid -ay no nods are created in /dev/mapper/. Verbous mode shows that devices are found:

WARN: locking /var/lock/dmraid/.lock
NOTICE: /dev/sda: nvidia discovering
NOTICE: /dev/sda: nvidia metadata discovered
NOTICE: /dev/sdb: nvidia discovering
NOTICE: /dev/sdb: nvidia metadata discovered
NOTICE: added /dev/sda to RAID set "nvidia_bddgdabd"
NOTICE: added /dev/sdb to RAID set "nvidia_bddgdabd"
WARN: unlocking /var/lock/dmraid/.lock

and something is done with them but nothing really happens.
I've moved from Mandriva to Ubuntu Edgy 6.10 lately. There were no problems in Mandriva and here I simply don't know what's wrong. Searched all over the internet but nobody has any solution for this situation...
