partman-lvm cannot access luks-crypted newly-created partition

[Michel D'HOOGE]

Binary package hint: partman-lvm

Trying to install Xubuntu Intrepid Ibex Alpha-5 on an EeePC 701 (4G internal + 4G SDHC memory card)

My partitioning steps are:
- sda1: use as /
- sdb1: encrypt using LUKS
- sdb1_cryptp1: replace default ext3 partition by LVM PV
- Start LVM partitioning
- - accept writing modification to sdb1_crypt

Then I get an error and console #4 reads:
partman-lvm: Can't open /dev/mapper/sdb1_crypt exclusively. Mounted filesystem?

Using console #2, I did:
# dmsetup ls
=> Reports sdb1_crypt, sdb1_cryptp1
# dmsetup remove sdb1_cryptp1
=> Then partman-lvm can start

Note: When I first encountered this problem, "dmsetup remove sdb1_cryptp1" wasn't enough so I did instead
# dmsetup remove_all
# cryptsetup luksOpen /dev/sdb1 sdb1_crypt

Then I can create my LVM partitions.

But when I tried to end partitioning and apply the changes, sdb1_cryptp1 is back and the creation fails. So maybe the problem is more with partman-crypt...

I tried to simply create an encrypted partition, without LVM and the problem is still present - so I guess the correct package is partman-crypto.

This bug was fixed in the package partman-lvm - 61ubuntu1

---------------
partman-lvm (61ubuntu1) intrepid; urgency=low

  * Backport from trunk (Jérémy Bobbio):
    - Fix size substitution when displaying partman-lvm/lvcreate_error.
    - Don't fiddle with label on devices of type loop (e.g. RAID or crypto)
      in update.d/lvm_sync_flag. (Closes: #494910, LP: #267048)
