ZFS Available and Used size

  • Hi,


    I noticed that the ZFS filesystem in the GUI under Storage / filesystems does not show the Total / Available and Used size. It just shows n/a.
    Also i noticed that somehow the used space is not correct.


    # zpool list
    NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
    onepool 3.62T 692K 3.62T - 0% 0% 1.00x ONLINE -


    But in my docker for example Radarr i only see 208.4 GB Free Space and Total 281.4 GB ???
    Why doesn't it see the 3.6Tb? it is if it only is seeing the OS OMV disk, but not the pool.


    Both are not correct as yesterday i have put about 16Gb of movies in my pool and the pool size didn't change is this a bug or am i looking wrong?
    Probably this is something simple that i just do not see


    Thanks for your help,
    Armand

  • Further investigation show that maybe i am copying to just a directory and not the pool

    So why doesn't it get mounted?

  • ok i think i run into this https://github.com/OpenMediaVa…nmediavault-zfs/issues/27



    root@nas:/# zfs get mounted -t filesystem
    NAME PROPERTY VALUE SOURCE
    onepool mounted no -
    root@nas:/# zfs mount -a
    cannot mount '/onepool': directory is not empty
    root@nas:/# zfs umount -a
    root@nas:/# zfs get mounted -t filesystem
    NAME PROPERTY VALUE SOURCE
    onepool mounted no -
    root@nas:/# ls /onepool
    docker downloads kids movies music photos series videos
    root@nas:/# mkdir poolcopy
    root@nas:/# mv onepool poolcopy
    root@nas:/# ls /onepool
    ls: cannot access '/onepool': No such file or directory


    root@nas:/# zfs mount -a
    root@nas:/# zfs get mounted -t filesystem
