Hi,
I got no secret and I am using kernel 2.0.36 on a SuSE 6.0 distribution (not the
SuSE-kernel!!!); but I didn't want to offend you.
There were a lot of question this days starting with "... mkraid doesn't work ..." and
most of the people forgot to add the force-option.
I set up raid0145-19990309 on a P166 and P200MMX, both are single processor machines
containing an AHA2940. I patched the kernel, did a menuconfig and enabling the
raid-options, recompiled it and started the machine again. Building the raidtools 0.90
was no problem and I set up the raid by using one of the raidtab samples. After all I
did a mke2fs /dev/md0, but I am not sure, if that is necessary.
The only problem I got is setting up the same raidtools on a SMP machine, both
processors running (compilation of the kernel fails), but using only one works.
That's all. I hope this helps.
Greetings, Dietmar
