Is there a way to remove BTRFS from a running opensuse system and convert to another file system, such as ext4? I did not see anything on line.
I can do it, but it is not trivial (the reverse is guru level). You need a rescue stick (use the opensuse xfce rescue image, at the live iso link), then do a full backup of the root partition to something else (excepting the snapshots), using rsync, format the root partition as ext4, mount it back, restore files, (edit *that* fstab), reinstall grub using yast (perhaps edit grub config to reflect filesytem change), reboot. You might use the home partition as destination for the backup.
OPTIONS="--archive --acls --xattrs --hard-links --sparse --stats --human-readable --checksum"
rsync $OPTIONS --exclude=/lost+found \ $FROM/ $DEST
I tried this approach and it appears to work. I ran into a probably silly problem when I allowed the distribution installation media to generate my partition setup. It has been a long time since I dealt with MBRs etc, but the installation media generated a bios grub partition. In the past I have always used the legacy 512B MBR. When booting I receive a "GRUB " printout and then nothing. Is there something obvious that I need to do? My BIOS is set for legacy boot. Is this correct? I can go to Yast2/Configuring the Boot Loader and write "Generic Boot Code to MBR" if this is the correct approach. I can boot from another disk on the same machine, and the ext4 file system appears to function properly. Thanks. I can open a new thread if you think I should.
