I'll see what I can do :-)
The problem could be resolved by removing one of the two external SATA
controllers (PCI card with ALI M5283) and using Kernel 2.6.20.6
Only removing the ALI PCI card brought the numbering scheme in line
again so the old (degraded) array became accessible again. Even with no
disks attached to it, the kernel did not get its disk naming in shape to
assemble more than one ("sdd") of the four old devices although all 4
devices could be accessed with "mdadm --examine" or fdisk.
Additionally, using 2.6.20.6 resolved the ghost device issue where one
SATA drive appeared additionally as a PATA drive, too. Now I could
create the new array and copy over all data from the degraded one.
<wipes sweat>
Are there any kernel logs that this time which might make it clear
what is happening?
Not really, the logs contain quite a mess of trying different kernels
and system configurations to get the data back
with the disc naming following the state of the moon.
I produced too much sweat to get the data back so I am reluctant to try
anything now that it works until my backup
scheme is somewhat improved :)
Thank you for your help.
