Some guesses - maybe they are right and someone can confirm.
hda1 and hdc1 are the raid0, the other ones are used as mirror devices.
If i would make a raid0 with dmsetup to make one block device, i should
get my partition back? Am i right?
How can i find out which disks are used as mirror and which was used as
stripe set - last 20 sectors or something, which information is
essential to know this?
Can i try various combinations and see if fdisks founds some useful
partition table? Can i do any damage to the raid set by using dmraid to
create the block device and searching for partitions on it?
Should be only read access - should be safe, shouldn't it?
kind regards

Hello.
Got a raid10 array on a pdc20270 controller, fasttrack100 tx2.
Some loss of power made some serious damage to the complete pc.
The disks however are still working - the controller is a little bit
broken - no boot message about the raid things, only ide does still
work, more or less ( dma errors etc. pp ).
So i took the drives and put in on a normal ide controller - they are
all recognized.
running dmraid on a 2.6.17 kernel, ubuntu edgy, does found nothing.
Drives are found as follows:
hda, hda1
hdb - unknown partition table
hdc, hdc1
hdd - unknown partition table
I know there was a 10 setup prior on these 4 disks - although i don't
know how the pdc controller does the mapping on 4 drives.
Is it possible to create the mappings for a raid10 again - to get the
only partition on those drives back?
Anyone a example, found many for raid0 or raid1, but nothing for 10 - i
don't want to do some damage to the raid ( i hope its still there ... ),
so i'll asking before.
thx for any help.
kind regards
Torsten
