Howto install Sabayon on a raid-0?

Postby dewete » Mon Oct 28, 2013 10:12

Hi,

Sabayon is recognising a BIOS raid 0 but isn't activating the raid. The installation ends with "no boot partition selected" - now wonder is the boot partition on the raid.

Any recommendations?

Thanks

>You don't want to install gentoo from scratch, so you make one of the USB Disk bootable. Have a look at GRUB to get an idea. Now you boot the usb disk, mount your gentoo on /mnt/gentoo and make a system backup with
cd /mnt/gentoo
tar -c [a-k]* lib* [m-z]* |gzip -9 > /mnt/part3/gentoo.tar.gz
cd
umount /mnt/gentoo
The term [a-k]* lib* [m-z]* is used to exclude lost+found. You have everyhting you need to setup the box again.
If you want to give dmraid a try, which has support for bios powered software raid, then you should zero out the disks with
dd if=/dev/zero of=/dev/sda bs=4k
dd if=/dev/zero of=/dev/sdb bs=4k
dd if=/dev/zero of=/dev/sdc bs=4k
