Thank you for the notes. I followed them, but I'm still not having any
luck installing. I go to shell and create the arrays and create the
config files, but when I switch back to anaconda, it doesn't detect
/dev/md10, only /dev/md11 and /dev/md12. I can't create another raid
device in anaconda. What am I doing wrong? I tried setting up LVM when
i first installed this, but it failed to boot.
I don't believe you can boot from any device that includes RAID-0 in
its components. This is because the kernel is what knows how to
drive a RAID-0 device, whereas the Grub loader knows how to do is
read linearly.
At a bare minimum, your /boot must be non-RAID0 and non-LVM.
I guess i forgot to mention a few things:
My boot is on /dev/md0 which is a raid1 array of 2 devices (/dev/sda1
and dev/sdb1) with 2 hotspares (/dev/sdc1 and /dev/sdd1).
My swap partition is on /dev/md1 which is raid0 array of 4 devices
(/dev/sd{a,b,c,d}2)
I want my / to be on /dev/md10 which is a raid0 array of 2 devices
(/dev/md11 and /dev/md12)
/dev/md11 is a raid1 array of 2 devices (/dev/sda3 and /dev/sdb3)
/dev/md12 is a raid1 array of 2 devices (/dev/sdc3 and /dev/sdd3)
Previously I had created an LVM over /dev/md11 and /dev/md12, but after
installation the system would not boot.
Now I'm trying to create /dev/md10, which works fine in the shell, but I
can't get it to show up in anaconda, so that I can start installing on it.
