    [Errors] Dolphin partition properties showing incorrect size

    Hi! I just installed Kubuntu for the first time and updated the system, I was exploring different components of the OS. While checking properties of root partition from the context menu, after calculating, it's showing the total size is 128.0 TiB! What I gathered from different sites, it's probably a KDE/ Dolphin issue. Now, is there a way to fix this or is it just a known bug? Can anyone kindly confirm me this?

    Relevant info:
    Description: Ubuntu 20.04.3 LTS
    plasmashell 5.18.5
    lsblk output

    Let me know, if anything else is required.

    Ho! I get that too. Is your root file system on a btrfs? Running snapper, or a tool like it?

    A bit of investigation, /proc is the culprit. /proc is a pseudo file system, in that it's contents are generated dynamically from various information the OS has about processes. It's certainly not 128 TiB; from a storage perspective it's zero. IMO dolphin should ignore it if calculating the size to show on a properties pop up, and /sys too.

    With btrfs, calculating sizes of snapshots is very complicated because every snapshot starts sharing almost all the storage of the subvolume that is snapshotted. After a few dozen snapshots, who owns what?

      No, on both end. I used ext4 for both Linux partitions, and no, I haven't setup any backup/ snapshot utility yet. Here's the partition info, if that helps. btrfs seemed too complicated!

      Also, thanks for the prompt response.


        same hear , but the context menu dose show the correct size of the disk , strange the same size misinformation for all of us lol
