Re: [bitfolk] Updating grub (going from lenny to squeeze)

Hi Alex, On Sat, Jun 11, 2011 at 08:28:11PM +0100, Alex Hudson wrote: Yeah this has come up a few times before. It's an issue with the grub package scripts not liking the fact that there is a /dev/xvda1 without there being a /dev/xvda. In the archives of this list you can find various workarounds that worked in the past, but successive versions of the grub package's scripts have got more and more complicated in their efforts to detect disk layout, and it's just not possible to fool them any more. So, the best way to fix this is to stop using xvda1 as a block device without there being an xvda.[*] The easiest way to do this without reinstalling your VPS is as follows: - You ensure that your VPS will find its block devices by LABEL or UUID in /boot/grub/menu.lst and /etc/fstab. This will enable you to later change the block devices without a problem. - You send a support ticket saying you've done that and are ready for your VPS to be rebooted with whole disks as block devices, and specifying what sort of day/time you would prefer for that to be done. - We will alter your config on our side so that you have xvda, xvdb, xvdc, etc. as block devices instead of xvda1, xvda2, etc. We'll then shut your VPS down and boot it again. Provided it has been set to find block devices by LABEL or UUID this should be routine and has been done many times, but if there has been an error that prevents the VPS from booting then we'll do our best to fix it for you. In the mean time the only thing that this is preventing you from doing is running update-grub, so you can continue putting manual kernel entries in your /boot/grub/menu.lst until you are ready to do this.
