Re: Adaptec 1210SA raid issues.

Further to this, I have found: http://people.redhat.com/~heinzm/sw/dmraid/

I'm installed the RPM, and re-compiled the kernel after the patches
required (giving me 2.6.7-mm4) compiled dm-mod as a module. I've modprobed
dm-mod so I have:

[root@zeus md]# lsmod
Module                  Size  Used by
dm_mod                 59260  0
<trimmed rest of list>

when looking at dmraid however, I get:
[root@zeus md]# dmraid -r
Failed to find sysfs mount point
Carrying on with /dev/
No Software RAID disks

now, what /dev entries does this actually look for? I have a RAID0 set up
in the BIOS of the 'raid' card. Ideally, I'd like to rescue this so I
don't lose the data on the array.

Is this not supported yet? or have I missed something?

Hi all,

Firstly I'm sorry if this has been asked before - I've had a quick skim
through the archives but with no joy.

I'm just moving away from the Adaptec drivers for the 1210SA SATA RAID
adapter (urgh at being locked into kernel 2.4.20!) to the sata_sil driver
-
and am having much more luck that I have a few months ago when I tried...

It see's the two drives:

[netwiz@zeus netwiz]$ cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: Maxtor 6Y160M0   Rev: YAR5
  Type:   Direct-Access                    ANSI SCSI revision: 05
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: Maxtor 6Y160M0   Rev: YAR5
  Type:   Direct-Access                    ANSI SCSI revision: 05

It sees the correct partition size (via fdisk)
Disk /dev/sda: 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/sda1             1     39859 320167386   83  Linux

But I can't mount /dev/sda1... My guessing is that as it's seeing two
drives, they're not being combined into one volume - however I could be
completely off base here. Is there something else I need to do?
