Subject: Problem booting via grub2
in software RAID system
Hello there --
I have a Debian squeeze workstation which uses grub2 as its bootloader.
The system has 2 hard drives: the root partition is a software RAID-1
array configured with mdadm; the boot partition is non-RAID (ext3). It
also has a DVD drive. The underlying architecture is AMD64, the CPU and
mobo are Intel.
Ordinarily, booting via grub2 with the configuration above works fine.
However, when I connect an external hard drive via a back-panel USB port, I
can't boot -- the boot hangs or freezes or something.
Through use of echo statements, I determined that the problem occurs in the
following stanza near the top of my grub.cfg file:
insmod raid
insmod mdraid
insmod part_msdos
insmod part_msdos
insmod ext2
The first statement executes correctly, but the second (insmod mdraid) is the
one which hangs.
Any suggestions for what might be wrong and/or how to correct it?
Thanks in advance for any help you can provide,
-PT
