Disk full for no apparent reason

  • OMV says my root sd card partition is almost full (see image below):



    However, I can't figure it out why. Things I've already done:


    1) Running ncdu -x /:



    2) Running docker system df (btw, my Docker stuff is on an external hard drive):

    Code
    TYPE TOTAL ACTIVE SIZE RECLAIMABLE
    Images 12 12 2.479GB 104.9MB (4%)
    Containers 12 12 891.4MB 0B (0%)
    Local Volumes 34 1 336.3kB 0B (0%)
    Build Cache 0 0 0B 0B


    So I just can't figure it out the reason at all. Any help will be appreciated, thanks.

  • Have you recently run a backup and the destination disk was not mounted?

    Simple and sure backup and restore: In a Scheduled Job: rsync -av --delete /srv/dev-disk-by-label-SOURCE/ /srv/dev-disk-by-label-DESTINATION/ (HT: Getting Started with OMV5)
    Server Software: OMV 5 (current) - My Main Server: Thinkserver TS140, Nextcloud, Plex, Airsonic, Navidrome, Ubooquity, Digikam, & Heimdall - My Backup Machine: NanoPi M4 (v.1), Pi-Hole - Odroid XU4 (Using DietPi) - Testing/Playing: hc2, xu4, Pi 3B+, Odroid H2.

  • Unmount Disks 1-4. Then look inside their mount point directories in /srv. They should be empty, but if they aren't that's your problem.

    Hi, thanks for the input. I've unmounted all drivers, and after that the mount point directories have vanished.



    Code
    pi@NAS:/srv $ ls -l
    total 12
    drwxr-xr-x 2 ftp nogroup 4096 Dec 3 2020 ftp
    drwxr-xr-x 3 root root 4096 Jul 18 00:01 pillar
    drwxr-xr-x 5 root root 4096 Jul 18 00:01 salt
    pi@NAS:/srv $

    So apparently that's not the issue.


    EDIT: LOL, I just noticed that the remaining space in root disk is now correct, as the image shows. Let me mount all drives again and see if the issue is fixed!
