hi! raid 1 arrays: I already have 2 systems running this same raid1 config. 1 sys has 2 120 gb 1 sys has 1 120gb and 1 200gb but matching the raid partitions this system here that is giving me fits right now has 1 250gb and 1 200gb. I tried it w/a new 250 gb for the 2nd drive but the same results. Will not boot. in druid, when I am config. the raid arrays, I always create the boot partitions in hda1 and hdc1 and make them primary...maybe I am doing wrong by giving them 200mb instead of 100mb but I do it in the other 2 raided systems I run and no probs. I then create the sys partitions: hda2 and hdc2 lastly, the swaps as hda3 and hdc3 ........................... grub: here's what I did/do and here's the results: linux rescue chroot /mnt/sysimage /sbin/grub-install /dev/hda ...the complaint/result: /dev/md0 does not have any corresponding drive I have tried: /sbin/grub-install /dev/hda (as a stab in the dark) it gives the same result /sbin/grub-install /dev/hdc also produces the same result I have done the following: dropped to grub # grub grub> root (hd0,0) result: Filesystem type is ext2fs, partition type 0xfd grub> setup (hd0,0) result: Checking if: "/boot/grub/stage1" exists ....no "/grub/stage1" exists...yes "/grub/stage2" exists...yes "/grub/e2fs_stage1_5" exists...yes Running: "embed /grub/e2fs_stage1_5 (hd0,0)"...failed(this is not fatal) "embed /grub/e2fs_stage1_5 (hd0,0)"...failed(this is not fatal) "install /grub/stage1 (hd0,0) /grub/stage2 p /grub/grub.conf"...suceeded done I messed w/cmos...oh, enable/disable S.M.A.R.T. Drive....bypassing cd- rom drive...so hd0 be the first boot...nothing changes...just "DISK BOOT FAILURE" etc thx! John Rise
