Hi all, I've just switched to ubuntu after years of Red Hat and Fedora.
I'm now installing my server with 3x500Gb HD SATA.
This is what I did:
Code:
sda1 4gb SWAP
sda2 250mb /boot ext3
sda3 496.1 GB RAID
sdb1 4gb SWAP
sdb2 250mb UNMOUNTED ext3
sdb3 496.1 GB RAID
sdc1 4gb SWAP
sdc2 250mb UNMOUNTED ext3
sdc3 496.1 GB RAID
I've created a RAID 5 with the 3 partitions sda3/sdb3/sdc3, and I'm running a LVM volume over it mounting "/"
Installed Xen and rebooted, everything works fine.
I now would like the system to bootup even in case sda (first device in the bios boot order) is failing. As /boot is not set in a raid I thought about copying the content of sda2 (/boot) into sdb2 and sdc2, modify the menu.lst of grub adding the options to boot from (hd1,1) & (hd2,1)
Looking at the above scenario I guess I would have to install grub on hd1 and hd2
Code:
grub-install hd1
grub-install hd2
this would make send to me as if sda is failing sdb is next in the boot sequence.
My only question is:
What about the fstab? this is into /etc (on the RAID 5) and statically points /boot to /sda2).
Do you see my point?
I just would like my system to ba able to boot properly even if one of the 3 HD Im using is failing.
Thanks to read!
