Re: Advanced RAID configuration in preseed
This is how we do 2x RAID1, altho on same disk (one for boot, other for
LVM)
# Parameters are:
# <raidtype> <devcount> <sparecount> <fstype> <mountpoint> \
# <devices> <sparedevices>
d-i partman-auto-raid/recipe string \
1 2 0 ext2 /boot \
/dev/sda1#/dev/sdb1 \
. \
1 2 0 lvm - \
/dev/sda2#/dev/sdb2 \
.
so it is definitely possible to *create* raid but I have no idea how to
partition many drives differently
Back in bad old centos days we just have script that was called during
install that partitioned it manually but I don't know how to tell
partman to use that specific device
