I'm also experiencing issues with grub-installer ignoring/overriding the
bootdev setting on Ubuntu Server 14.04.2 w/ Software RAID (at least when
set using the debconf-set command).
I had to resort to using the same type of workaround as mentioned in
post #27, so I thought I'd share some details of it here for reference:
...
# Identify disks larger than 1 TiB
d-i partman/early_command string \
DISKLIST=$(for f in $(list-devices disk); \
do fdisk -l $f 2>/dev/null | sed -nr 's|^Disk (/[^:]+):.* [0-9]{13,}
bytes$|\1|p'; done | sort); \
echo "${DISKLIST}" > /tmp/disklist
...
# Manual GRUB installation
d-i grub-installer/skip boolean true
d-i lilo-installer/skip boolean true
d-i preseed/late_command string \
in-target apt-get -y install grub-pc; \
for line in $(cat /tmp/disklist); do in-target grub-install --force "${line}";
done; \
in-target update-grub
...
This works for me on two separate systems where one has the (system)
disks on sda+sdb and the other on sdb+sdc.
Here is an expanded version of the first part which includes the
partition recipe:
# Identify disks larger than 1 TiB
d-i partman/early_command string \
DISKLIST=$(for f in $(list-devices disk); \
do fdisk -l $f 2>/dev/null | sed -nr 's|^Disk (/[^:]+):.* [0-9]{13,}
bytes$|\1|p'; done | sort); \
echo "${DISKLIST}" > /tmp/disklist; \
DISKA=$(echo "${DISKLIST}" | head -n 1); \
DISKB=$(echo "${DISKLIST}" | head -n 2 | tail -n 1); \
debconf-set partman-auto/disk "${DISKA} ${DISKB}"; \
debconf-set partman-auto-raid/recipe "1 2 0 ext2 /boot ${DISKA}2#${DISKB}2 . 1
2 0 ext4 / ${DISKA}3#${DISKB}3 ."
The rest of the partitioning is just a standard 'd-i partman-
auto/expert_recipe string multiraid' config that does not need to
reference the disk variables.
