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. Correct. Leave it, don't touch it. It is not /boot, it is different.
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.
That's a possibility that normally doesn't harm, unless you use your own. Simply go into yast boot module, and change the timeout, one second up or down. That tells yast to write grub again. But make sure that all the settings are correct in YaST (it is a different partition now). Why Legacy bios mode?
I can boot from another disk on the same machine, and the ext4 file system appears to function properly. Thanks.
You have to boot another and chroot this one.
I can open a new thread if you think I should.
No, let's keep the entire process of migration in a single thread. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.0 (Legolas)) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
