Hi, i currently run my main workstation with SuSE 10.1 (X86_64) with 2x250GB Sata disks on RAID1, right now i have two arrays, md0 for /boot and md1 for lvm. I'm planning to upgrade to 3x500GB SATA disks on RAID5 and would like to manage all the space with lvm to make things easier (not creating a tiny partition for /boot or having to worry about grub when replacing disks). Is it posible to put /boot on a pendrive so that i can have grub and /boot out of my way when replacing failed disks? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Do you know an example where fdisk plus mke2fs can't change that? fwiw I have a system whose BIOS has decided not to boot directly from hda, Couldn't figure why, but booting grub on CD is fine, and this works: root (hd0) chainloader +1 boot There is, of course, no reason /boot can't (with a little work) be on a CD. -- Cheers John Summerfield -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi, why wouldn't you use it?, i barely poweroff that pc, so i wont really stress the pen drive.... And the last time i checked, grub didn't support /boot on raid5, that's why i would like to avoid installing on the HDD. The problem, i think, would be to mount the pendrive on /boot at the installation stage...

It can work on an already running system, but i'm looking to replace a RAID1 (2x250GB) with a RAID5 (3x500GB) and use just one partition for md0, i'll need to to mount the pendrive as /boot on the system installation and probably that's not an option with yast...
