** Description changed: - Binary package hint: debian-installer + [IMPACT] - I have a ubuntu 7.10 beta server I'd like to reinstall from scratch. - During the disk partitioning, I'd opted for "Guided - Use entire disk - and setup LVM" Part way through it informed me that the volume group - name was already in use. Surely this option should setup a new LVM - instance and use the entire disk, even if a LVM instance already - existed? + * Fail to pre-seed automatic LVM installation on machines with: + - empty / new partition table + - not-zeroed out disks + - which had the same partition layout + - and the same volume group names - How can I blank this without manually having to create volumes? I think - this is a bug + * this affects large scale automated installs / deployments, as it is + very easy to get all of those conditions when reinstalling. + + * To fix this bug partman-auto-lvm should be updated with the proposed fix + * the fixed partman-auto-lvm should also make it onto affected images + + [TESTCASE] + + * Pre-seed or manually execute "Guided partitioning - LVM" + * Remove/Clear partition table with e.g.: + + # fdisk /dev/vda << EOF + o + w + EOF + + * Pre-seed or manually execute "Guided partitioning - LVM" again + + [Regression Potential] + + * while the current behaviour is broken, it did allow to "resurrect" + LVM groups by bailing out the install after the zombie VGs groups became + detected, but it is not guaranteed that the resurrected VGs are correct: + the partition can be too small and VG can be incomplete (only 1 out of + many physical volumes). Some people may have been relying on this. The + correct behaviour will attempt to delete the zombie VGs by asking a + question that can be pre-seeded or manually backed out of.
