I have a debian with a raid1 on it. Both HDDs have bootable flags and grub setup in MBR. If I only start up with sda, linux boots. If I only start up with sdb, grub shows up and says
Decompressing Linux... crc error -- System halted
I have reinstalled grub a few times now but still nothing.
It goes like this:
/dev/md0 contains /dev/sda1 /dev/sdb1
find /boot/grub/stage1 shows (hd0,0) (hd0,1)
The line that boots Linux shows:
This kind of renders my "redundant" array useless.
update: just to mention, these are 2 different HDDs, sda is 320gb and sdb is 400gb. Both are WD and both have exactly the same partitions, cloned using sfdisk.
