Looks like some combination of defragging & balancing has done the trick! The space that was previously marked UNREACHABLE is now UNUSED, and my disk space is back to normal:
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 227G 105G 103G 51% /
Thanks for the wiki link, Btrfs is new to me and I’ve definitely got some learning to do
Just one drive, it was a clean Linux install with no funky stuff going on. I’ll have to look into Btrfs cleanup more, last time I did it the disk just filled up even more
Legend! It found a second filesystem named “UNREACHABLE”:
It looks like an exact duplicate of my main filesystem “/@rootfs”, I’m guessing this is why my disk space filled up. Do you know how I’d go about removing the duplicate? (If it’s safe to do so)
Interesting, this could be it? I haven’t configured any mounts on this device yet, but when I tried one of the other suggestions from this thread and use btdu, I get this error:
$ ./btdu -x /
Fatal error: The mount point you specified, "/", is not the top-level btrfs subvolume ("subvolid=5,subvol=/").
It is the btrfs subvolume "subvolid=256,subvol=/@rootfs".
Please specify the path to a mountpoint mounted with subvol=/ or subvolid=5.
E.g.: mkdir /mnt/sda1 && mount -o subvol=/ /dev/sda1 /mnt/sda1 && ./btdu /mnt/sda1
Note that the top-level btrfs subvolume ("subvolid=5,subvol=/") is not the same as the root of the filesystem ("/").
I’m fairly new to the workings of Btrfs so this is jibberish to me right now, but I’ll look into it more
EDIT: Nevermind! I was just using the tool wrong. I needed to mount my btrfs “sub-volume” then do the scan against that:
sudo mkdir -p /mnt/btdu
sudo mount -o subvolid=5 /dev/sda1 /mnt/btdu
sudo ./btdu /mnt/btdu
ncdu
Oh this one is very cool! Unfortunately it also only shows the same 101GB being used:

There is one listed:

Looks like it is just my filesystem though?
For music prod on Linux, have you tried Reaper?
Good solution, cheers! I also followed the other commenter’s idea to add it as a KDE shortcut so I can use it on demand.
I guess I’ll just need to be careful not to paste a bazillion lines of text lol
Works awesome! Thanks for introducing me to xdotool, what a helpful utility. Question: what does the --file flag in your command do? I can’t find it in the manpage
Win11 doesn’t let you past setup if you dont have an internet connection.
That account is less than a day old and you should definitely not do whatever it is they tell you to do
