So far I've installed 13.10 64-bit server on 2 different machines. In
each case, I want / on a software RAID 1.
The first server is a Thinkmate superMicro based box with 2 OCZ SATA
drives. In this case, I was able to install the software RAID without a
hitch.
The second server is a Dell Poweredge R610 with 2 69GB SAS drives
attached to Dell SAS 6 host bus adapter. In this case, the system
install seems to go well, but then the machine won't boot. On my first
install attempt, I never got a console. On the second attempt, I hang
at a grub rescue prompt:
Error:
file '/boot/grub/i386-pc/normal.mod' not found
Grub rescue>
None of the grub rescue commands work, indicating that grub isn't
finding anything. Oddly, even if I don't try and put / on a software
RAID (i.e. I just install the system to the first disk), I don't get a
bootable server -- i.e. I never get a console. However, if I remove the
second disk from the machine and try the install again, everything works
properly.
As a side note (because I've seen this with previous versions of the
server OS), why is it that a software RAID 1 configured from the
installer sometimes comes up as /dev/md0 and sometimes as /dev/md127,
seemingly randomly? And I've even had it change from /dev/md127 to
/dev/md0 after the first sytem reboot.
I'm not sure if I should file this a bug on launchpad. The workarounds
are to install the OS on the system with only one disk, put the second
disk back in and convert to software RAID 1 after the fact or boot from
a Live CD and try and fix the grub-install (I'm pretty confident about
the first option, not so much the first one.)
