Re: [gentoo-sparc] SILO and OBP conflicts?

[Jason Williams]

Thank you for the reply. I am a little late receiving it because I had
forgotten check this email thread lately. However, I did get it
working, and interestingly enough one of your listed problems was the
same as I had. It turned out to be the software raid. Apparently
software raid inserts header information at block 0 and then stores
the array at the end of the partition, and of course as we should all
know, silo also wants to use block 0. The only part that was new to me
about this process was the fact that raid uses block 0, so of course
it's going to conflict with silo.

Anyways, I ended up separating off my boot directory to it's own
partition and for simplicity, made it the first partition on each
disk. Now I have all my partitions working as raid1 except sda1 and
sdb1. With these I now just use $(dd if=/dev/sda1 of=/dev/sdb1)
anytime I upgrade the kernel or silo. I know there's a way to have
silo boot from a different block other than 0, but that task will wait
for later play. Right now I'm just happy to have my server up and
running at full capacity.
