LVM - Re-install without data loss

Is there a way to re-install the system with an LVM config and keep my /home and such? Or do I need to backup everything and install from the beginning?

I believe you need to backup the data and setup partitions then restore the data. LVM is pretty fundamental since it is a container for virtual partition and not a file system.

Yes.

If it is an encrypted LVM, then you have to give the installer the encryption key when requested.

In the partitioning section, click on “Import partitioning”

You could also do this with expert mode create partitioning, but that is more work than importing.

I’ve been doing it this way (import partitioning) for 12.1, 12.2, 12.3. It works fine.
