Bug 1027375

+++ This bug was initially created as a clone of Bug #1024076 +++

Originally abrt dinged bug 1021507 with this.

Description of problem: When creating a thinpool LV with the same name as existing, I get a crash; by default for thinpool LV's, the installer isn't checking for existing names and can propose a default name for a new LV for an existing LV of the same name thus running into the crash.


Version-Release number of selected component (if applicable):
anaconda-20.25.4-1


How reproducible:
Always when new name = existing name, but so far only with Thin Provisioning does this happen by default.

Steps to Reproduce:
1. Minimal package set install to single disk, single LVM Thin Provisioning via Guided path.
2. Reboot to installer, custom path.
3. Remove existing fedora-home LV.
4. Reuse existing fedora-swap LV.
5. Create new mount point / without size value.
[I note that it makes the name of the LV "root" which is the same as existing LV.]
6. Begin installation.

Actual results:
Crash.

Expected results:
Error message about the conflicting new and existing names instead of crash.
LVM thin provisioning should check existing name and propose a non-conflicting name, which is how conventional LVM works.

Here's a link to an updates image that should fix this problem:

Please report back with results.

With updates image applied, adding a new root LV as device LVM Thin Provisioning, the problem doesn't occur in that the new / is named root00. If I try to intentionally change it to root, it snaps back to root00.

Bug is fixed, marking as verified, remaining crash discussed in bug 1024144.


Clarified steps, attempting to reproduce this bug with the updates.img:
1. Minimal package set install to single disk, single LVM Thin Provisioning via Guided path.
2. Reboot to installer, with comment 5 updates.img applied, custom partition path, with Partition Scheme pop-up set to LVM Thin Provisioning.
3. Remove existing fedora-home LV.
4. Reuse existing fedora-swap LV.
4. Reuse existing /boot by reformatting.
6. Create new mount point / without size value.
7. Begin installation.
Succeeds and is bootable.

This bug was about new thinp LV's by default named the same as existing, then crashing, and that's no longer happening with updates.img: new LV is named differently by default, and even if I try to intentionally name it the same as existing, I'm thwarted. Thus, this is fixed.
