howto upgrade / autorun no longer possible with newest patch/raidtools??

[Claudia =?ISO-8859-1?Q?M=FCller]

hallo,

I have 2 questions:

1. How is it possible to safely upgrade an existing raid array to the
newest Kernelpatch/raidtools?
I tried following steps: got an original kernel, patched it, compiled
it. Rebooted, the raidarray could not be initialized automatically
anymore. I stopped the raidarray, compiled the new raidtools, and tried
to mkraid --upgrade /dev/md0 - with no success. what do I miss?
Unfortunately I did'nt keep the error messages?

2. I made a new raidarray with clean disks, successfull. I set the
Partition ID of the first disk to 86 for autorun. After reboot, it did
not work. If I remember well it was saying something like autorun is not
possible with newest raidtools 0.90. If I do raidstart /dev/md0
everything works fine.
Any comments?

thanks, Claudia
