So I’ll try to start from the beginning.
Wanted to move system from 2 SSD drives to 1
Had @ and @cache on one SSD and @home on second
I used timeshift for my ‘backups’ - insurance for system upgrade failure.
- I created read only snapshits of @, @home, @cache
- I mounted /dev/sdc1 to /mnt
- I did btrfs send <snapshots from 1> | btrfs receive /mnt
- I did writable snapshots
- I dismounted 2 SSD drives and mounted third drive to laptop
- I did fstab adjustments and grub reinstallation to new drive
After this my system booted up. But when I checked:
btrfs subvolume list /
I had 5 subvolumes instead of 3
When I deleted 2 extra subvolumes {portables, machines} with btrfs subvolume delete they were recreated after reboot.
I checked my previous configuration (with 2 disks) and there were 3 subvolumes. No machines or portables.
So I decided to let go.
Today I wanted to delete one of timeshift snapshots.
I couldn’t do that because of nested subvolumes.
So I did as I said before - mount, delete (with btrfs subvolume delete), umount, delete
And after this after reboot instead of subvolumes machines and portables I’ve found directories.
And as I said. I’m happy with it because I like it this way. But I don’t like my lack of understanding
