Hi all,
I just finished writing and testing a little patch for partman-auto-lvm to let
it use all available disks in the machine for a single VG.
It can only be used by preseeding for now (partman-auto-lvm/use_all_disks) and
will erase all content in the disks other than the one used "by default".
Reading the code to write this patch lead me to ask why, in
partman-auto/display.d/initial_auto, there's a loop around calls to
autopartition and autopartition-lvm as there can't be more than one disk in
$disks. I've tried to preseed partman-auto/disk with two disks, but the
installer hangs. If anyone here knows I'm really interested about the answer.
Just a last thing : this patch was only tested (for now) using qemu virtual
machines.
Cheers,
Grégory
