Description Artur Szymczak 2013-06-19 02:49:02 EDT
Description of problem:
When you have LVM with snapshot, anaconda hangs on trying to remove original, before removing snapshot.

Version-Release number of selected component (if applicable):
Fedora 19-TC5

How reproducible:
Create LV with snapshot, and then try in anaconda to remove all partitions, lvm and etc. Then try to install system (anaconda will try to remove all former disk layouts and will hang on removing original LV).

Steps to Reproduce:

Actual results:
Anaconda hangs and is tryoing to remove LV before snapshot.

Expected results:
Anaconda should first remove snapshot, then LV (original)

Comment 1 Fedora Blocker Bugs Application 2013-06-19 06:57:19 EDT
Proposed as a Blocker for 19-final by Fedora user ajes using the blocker tracking app because:

 "The installer must be able to create and install to any workable partition layout using any file system offered in a default installer configuration, LVM, software, hardware or BIOS RAID, or combination of the above"
This bug, prevent from install using any layout (including default) without intervention (removing lvm by hand in cmdline).

I tried to reproduce this and anaconda crashed, see bug 975955.
Comment 3 Adam Williamson 2013-06-19 12:40:23 EDT
Discussed at 2013-06-19 blocker review meeting: http://meetbot.fedoraproject.org/fedora-blocker-review/2013-06-19/f19final-blocker-review-7.2013-06-19-16.01.log.txt . This is a corner case: LVM snapshots are not that commonly involved in Fedora installs. dlehman tells us the code around them in anaconda is already not in great shape overall, and he doesn't think it's a great idea to try and fix this at this point in the cycle. Given that input, we agreed to reject this as a blocker and freeze exception issue because we're as likely to make things worse as better by trying to fix this at this point. Re-assigning the bug to Rawhide - we may close it as a dupe of 975955.

Comment 5 Adam Williamson 2013-06-20 21:44:35 EDT
dlehman mentioned on irc today he had a fix for this which looked rather safe - do you want it re-proposed as an FE? is the patch available for review?
Comment 6 Fedora End Of Life 2013-09-16 10:12:42 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 20 development cycle.
Changing version to '20'.

Feel free to try this against F21 Alpha or Beta and reopen if the issue remains.
