Hi all.
sorry for an immediate question after subscribing, but I've managed to back myself into a frustrating corner. I've done some googling and come up dry, I figured I should try to post to the list while I dig through the archives.
I have an issue with grub on a centos reinstall. my system previously had 1x 120g ide drive, 3 1tb sata drives in raid 5 md, 2 300 g in a raid 1 md,the /boot partition was on the ide drive, os on the raid 1 in a volume group and everything seemed fine. I downloaded the x86_86 iso a few days back and decided to just to a complete reinstall rather than burn myself with some odd upgrade path trying to put newer, larger drives into a md with a much smaller drive.
I've since purchased some new drives and changed to 1 120 ide, 4 1 tb sata, 2 3tb sata. I've tried a few different combinations of install locations (e.g reused the ide as /boot, a 512 mb slice from a 1tb drive for /boot) but every layout I try seems to end up with a grub config that can not find the OS (if memory serves, the message comes back as error 15: file not found, hit return to reboot)
the thing that seems odd to me is when I do the reinstall, the hdds seem to start much higher than I'd expect. there's no /dev/sda, b, c, d, ... I think they start at i.
does anyone have some suggestions for what to try for this issue? Thanks.
