Description Kamil Páral 2023-04-26 10:44:35 UTC

This is a fork of bug 2186158. That one was changed to cover only Custom partitioning, and this bug is supposed to cover the same use case in Blivet-GUI partitioning.

Btrfs filesystem can't be reformatted, even if you remove all subvolumes which are present on that filesystem. It is expected that I should be able to reformat it in that case, but I still can't.

See the second half of attachment 1957109 [details] for a video demonstration, and bug 2186158 for a more detailed description.

The only workaround seems to be a complete removal of a partition and creation of a new partition.

Reproducible: Always

Steps to Reproduce:
1. Create a default Fedora Workstation 37/38 installation (using btrfs). I only tested BIOS mode, but it doesn't probably matter.
2. Run the installer and try to use the former root partition (vda3 in my case). Reformatting the filesystem is expected.
3. Anaconda doesn't allow you to use the partition, you have to completely re-create it.

Proposing as a final blocker due to a possible violation of https://fedoraproject.org/wiki/Fedora_38_Final_Release_Criteria#Disk_layouts

This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.
