Subject: debian-installer: allow to 'reuse' encrypted volumes

Date: Fri, 16 Nov 2007 12:50:05 -0500

Package: debian-installer
Version: 20070308
Severity: normal


I had first installed i386 system with encrypted /home and swap. Then I
decided to install also amd64 build -- reusing both encrypted
partitions. Although I checked out smth like 'delete data' in the
encryption setup menu, which I treated as 'preserve/don"t touch', it
did reinitialize them and I had to recreate filesystems on top.

So I think 'Delete data' must be named 'Wipe out data', and another item
in the menu should be 'Reuse' or 'Keep existing encrypted volume'

Thanks in advance!

It is actually possible to reuse existing encrypted LVM volumes by following 
the procedure documented on [1] just before starting the partitioner.

Well, almost.
I did have one strange issue with that procedure though: after crypto and 
LVM had been activated, partman did not recognize the existing file systems 
on the logical volumes even though they could be mounted. And even though 
the partman log _does_ indicate that the partition was recognized.

However, I completely agree that it should be possible to do this in a 
simpler way. Reassigning your suggestion to the appropriate component.

Maybe we should have a general option "Detect existing encrypted and/or 
logical volumes" on the partman main screen.

Cheers,
FJP

This seems to be an issue in init.d/50lvm from partman-lvm. That script will 
basically always create a new loop label on a logical volume and create a 
single partition. This is not really necessary if the LV already has a 
partition and prevents existing partitions from being detected.

Cloning to partman-lvm for this issue.

 partman-lvm - Adds support for LVM to partman (udeb)
Closes: 451970
Changes: 
 partman-lvm (56) unstable; urgency=low
 .
   [ Frans Pop ]
   * Only check partition flags if we've not already determined the device is
     used for LVM.
   * Don't create label and partition for LVM volumes if they already have a
     partition. Needed to allow to use existing file systems on LVM volumes but
     additional changes will be needed for that to be properly supported.
     Closes: #451970.

   [ Max Vozeler ]
   * Replace code to commit partman changes to disk with call to commit_changes
     from partman-base (>= 113) and version the dependency accordingly.
