Comments/Problems:
The partitioner seems to have a problem when placing LVM PVs on top of
encrypted volumes on top of RAID devices. I saw no mention of this in
the errata (http://www.debian.org/devel/debian-installer/errata), but
i haven't tested it against a daily build yet either.
In this example, there is a 2-component RAID1 mirror /dev/md1 from
/dev/sda3 and /dev/sdb3. /dev/mapper/md1_crypt is created by layering
an encrypted volume over /dev/md1, and configured via partman.
At this point, i was returned to the main partman screen, but if i
select the md1_crypt device to try to make it an LVM2 physical volume,
partman instead offers to put a partition table on the device, which
doesn't make any sense. Perhaps dm-crypt over RAID devices are
somehow not being flagged as "loop" or something? Partman seems to
work as i expect it to if it's just dm-crypt over a raw device.
I was able to work around this by getting as far as the above, opening
a shell in a separate session, doing pvcreate, vgcreate, and lvcreate
From the separate shell, and then restarting partman via "Go Back" and
"Partition Disks". At that point, partman recognized the LVM pieces
and let me work with them as i intended.
FWIW, this arrangment (LVM over dm-crypt over RAID) seems like a
reasonable common one, so it should be easy to configure from d-i.
Thanks for making a very useful installer!
