Reinstalling grub on a RAID 0

I want to make my Arch installation a bit more fancy. So, I installed the grub-gfx package and did the changes to my menu.lst file in /boot/grub. Then I need of course to reinstall grub again so I do

grub-install /dev/mapper/isw_baaggideei_Volume0

but it fails. How do I reinstall grub when using RAID 0 (fake-RAID). I also tried the installation mention in wiki for fake-RAID and I can grub gets installed but no background appears eventhough it is in menu.lst file.

Regards

André

Grub-install gives this error

#  grub-install /dev/mapper/isw_baaggideei_Volume0
/dev/mapper/isw_baaggideei_Volume0 does not have any corresponding BIOS drive.

Re: Reinstalling grub on a RAID 0

I noticed now after installing grub-gfx that when machine boots, right after grub I get errors saying

Buffer I/O error on device sda3, logical block 495904
end_request: I/O error, dev sda3, sector 3967232

Where do these come from?

Regards

Re: Reinstalling grub on a RAID 0

I'm also getting errors regarding
RTNL net/core/fib_rules.c: error
RTNL net/ipv4/imgp.c: error

Any ideas why I get these errors? How can I reinstall grub, should I reinstall it from CD like in the fake-RAID guide because grub-gfx is installed but the background isn't showing up. This leads me to believe that grub hasn't been reinstalled as I though, hence it is ignoring the background option.

Re: Reinstalling grub on a RAID 0

maybe pastebin your menu.lst install normal grub if you cannot get grub-gfx working right

Re: Reinstalling grub on a RAID 0

I don't think you can install grub with stripe raid. I'm running a RAID10 setup (MDRAID, so stripe and mirror in one action) and must have a separate RAID1 (mirrored only) array for my boot files. The reason is simply that GRUB cannot read the files off of the striped RAID array.

edit: Just noticed that you said fakeraid, so I assume this is some low-cost hardware solution that does the actual RAID'ing in software drivers. I'm not sure how this will differ from my MDRAID setup. I still don't see why people insist on using fakeraid controllers in RAID mode instead of switching them to SATA mode and using mdadm to setup arrays that are hardware agnostic.

Re: Reinstalling grub on a RAID 0

I'm gonna try to re-install the machine and install grub-gfx from the beginning instead of grub. So my question in this regard how do I mount and external usb stick/drive during the installation mode?

Re: Reinstalling grub on a RAID 0

I tried a reinstall but still no change. The splashimage isn't recognised for some reason, so I bug reported it.
