Intrepid upgrade removed EVMS but should not have allowed upgrade

[Ken Geis]

I just ran the dist-upgrade to 8.10. I saw that during the cleaning up phase that it was planning on removing EVMS. I assumed that EVMS functionality had been replaced by some other package, so I agreed to have it removed. Now my system won't boot because it can't see /dev/evms/root.

TEST CASE:
1. use hardy (e.g. server or a chroot)
2. install evms from universe and create a evms volume and mount it
3. enable normal upgrades in /etc/update-manager/release-upgrades
4. run upgrade (e.g. via do-release-upgrade )
5. verify that evms is removed at the end of the upgrade

6. repeat 1,2,3
7. run upgrade vie "update-manager --proposed or do-release-upgrade --proposed"
8. verify that the upgrade will abort

So I just read about evms being deprecated in Ubuntu 7.10. I booted SystemRescueCS and followed instructions in the wiki for converting evms volumes to md volumes. I'm up and running, but I still think that the upgrade script should have warned me that it would make my system unusable.

Thanks for your bugreport.

Could you please attach the files in /var/log/dist-ugprade/ to this report? It looks like indeed evms was removed from the archive entirely.

[Michael Vogt (mvo)]

I will add evms to the removal blacklist in intrepid. That will ensure that its not removed.

For hardy->next-lts I will add code that shows a dialog with a propper warning about it. This is difficult/impossible for intrepid because it means we break the string freeze.

[Michael Vogt (mvo)]

I change the current development branch for update-manager so that it will display a error and reuse to upgrade if /proc/mounts contains evms mounts.

[Michael Vogt (mvo)]

I discussed this in our development meeting and the agreement was that we should show a propper error message on intrepid upgrades too (even if it means a untranslated message). This error will shown *only* to people using evms, so it should be fine.

[Ken Geis (kgeis)]

Here's all of my upgrade logs, in case you still need them. Looking through them, I found another bug to file too! (upgrade added relatime to ext3 fs w/ noatime already specified)

[Michael Vogt (mvo)]

@Ken: thanks for the logs and thanks for the additional information about the relatime bug.

For the verification of this fix some instructins how to create a evms mount would be helpful. If you could help with the intructions how to create one (on a free disk or parition) with the evms-cli tools, that would be most appreciated.

[Ken Geis (kgeis)]

Sorry, I can't really help on creating an EVMS volume with the CLI tools. It's something I did once, a couple of years ago, with the GUI tools and the EVMS manual in front of me. Since I'm not going to use EVMS any more, and I don't have a machine I can just play around with, it's hard for me to justify such an effort.

Accepted into intrepid-proposed, please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

This bug was fixed in the package update-manager - 1:0.95.1

---------------
update-manager (1:0.95.1) jaunty; urgency=low

  * DistUpgrade/DistUpgrade.glade, DistUpgrade/window_main.ui:
    - show 9.04 upgrade target
  * debian/rules:
    - calculate demotions based on intrepid->jaunty
  * DistUpgrade/DistUpgradeCache.py:
    - when the dist-upgrade calculation fails, show the reason
      why in the error dialog (LP: #281286)
    - when a meta package can not be upgraded, show a proper
      error message with the package in question
  * DistUpgrade/DistUpgradeQuirks.py:
    - abort ugprade from hardy if evms is used in /proc/mounts
      evms got removed from the archive in intrepid (LP: #292179)
    - do not add "relatime" if "noatime" is already given (thanks
      to Ken Geis)
  * DistUpgrade/removal_blacklist.cfg:
    - remove overly broad postgresql regexp
  * DistUpgrade/DistUpgradeCache.py:
    - do not limit the removal blacklist to downloadable packages,
      this limits it too much
  * check-new-release:
    - install check for new releases into update-motd.d/daily

This has been in -proposed for 2.5 months. Any testers?

[Martin Pitt (pitti)]

Any testers? This has sat in -proposed for almost 300 days. I'm going to remove this package from intrepid-proposed again soon, if no testing feedback arrives.
