Available space on the SSD twice as much as the real volume.

Good day! This is the first time I come across this: the new LM19.1 Mate on a 512Gb Phison PS3111-S11 SSD with btrfs shows twice as much disk space in System monitor's System status. Does anybody faced this problem? How in theory it could cause problems in the future? Thx!

You have / and /home mounted on the same volume as subvolumes. Btrfs subvolumes don't have an individual size or used or free space. When queried they will report the size and used and free space of the volume they are on. Hence you see the same numbers twice.

Thank you for your reply! I assumed that this was due to the peculiarities of the btrfs file system, which I use for the first time. I’m more worried about whether it will cause errors in the future when the real SSD free place will come to it's end.
