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
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?


I got this on one of my joke accounts years ago.
I googled “3d face generator”, clicked on the first website, and slapped in an image of trump. Then I just rotated the 3d model following whatever the instructions were, and it worked lol
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


I had a similar problem, it was caused by undervoltage. Are you using the official power supply?


Yep it’s not near finished. This is one of those projects that’s sat in my “keep an eye on it” bookmarks for a good while, I figured I’d post it to get some attention on it, because it does look very promising.


I found some here: https://docs.spacebar.chat/setup/server/#setup


Got hit with this in the middle of work. We only have one customer using CrowdStrike, and only staff PCs, no infrastructure. But this one is REAL bad, caused by turning your PC on, and cannot be patched - each affected PC needs to be manually fixed. Would not be surprised to see Linux usage go up after this.
It depends entirely on the company you work for. Even then, I wouldn’t exactly describe the work as “chill”


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
