The installer didn’t create a @home for my home partition, for reasons not yet clear to me. Everything is working fine, but since it’s btrfs, shouldn’t home be in a subvolume? How can I create one now? I’ve done a lot of searching and some of what I’ve found seems either contradictory or very complicated.
give us a little hint by providing the installer logs:
sudo cat /var/log/endeavour-install.log | eos-sendlog
Installe ris set to create a subvolume for home… as long as you do not amnually change the install process.
thats the used scheme…
If you put /home on it’s own partition, it won’t create a subvolume.
This is easy to fix.
- Take a read/write snapshot of
/homenamed/home/@home - Edit
/etc/fstaband change the mount for/hometo this new subvolume - Test it with
sudo mount /homeand verify that the mount is correct - reboot
- Once everything is working properly. You can delete the old data.
did overread this one indeed… 
Thanks Joe. dalto, I think I’m stuck at your first bullet. I’ve read that you can only take snapshots of subvolumes, which of course my /home is not yet. Can you help me with exactly how to do that?
sudo btrfs subvolume snapshot /home /home/@home
Sorry, I guess I need help with the fstab.
The snapshot was created in /home, so now in /home is @home and dave.
UUID=adfcd37e-a3a3-4292-b86d-fbc745610698 /home btrfs subvol=/home/@home,noatime,compress=zstd 0 0
…and without the /home in <options>. Tired of restoring the backup in emergency mode. 
It is just subvol=@home
Awesome, almost there. Seems to be working properly, btrfs subvolume list /home now shows @home and it shows up in btrfs-assistant. Last question, I hope. Final bullet… where is the old data?!
It isn’t mounted anywhere.
You need to mount that device at /mnt (or anywhere else you prefer)
Don’t pass a subvol option and it should mount the root.
When you look in /mnt you should see @home and dave.
Don’t touch @home. You should be able to delete dave. Then unmount it from /mnt
That being said, it is not urgent to do this right away if you would prefer to wait.
Makes sense. I have a lot to learn. Thanks!
