I recently formatted my
/home partition using BTRFS, but since it was my first touch with this FS, I didn't know about sub-volumes.
Yesterday I reinstalled my Linux Mint and selected to mount my existing home partition as
/home. Now I was surprised, that my files first seemed to be lost, but then I noticed that Linux Mint created a sub-volume called
@home next to my existing user home folder.
Current situation is the following disk layout: 250 GiB SSD -- 64 GiB / (BTRFS) -- 8 GiB swap -- ~170 GiB /home (BTRFS)
When I try to move my home folder into the
@home sub-volume, I get the error that there isn't enough space left (?!) although there's ~50 GiB left on this partition and I want to move, and not to copy the files.
I haven't any other disk right now that I could reformat to any non-NTFS format, which would be required to keep any symlinks..
Now I got the question: How to move the files from the folder into the sub-volume correctly? And why doesn't moving the files work?
