OMV WebGui Refusing Login (Redirect?)

1st Official Post

    So having one of those days. Could use some help. Literally went on vacation for a week and came back to an OMV webgui that won't let me login.


    The login screen displays correctly, and prompts with an error message when the user/password is typed incorrectly. However, when the proper user/password is used (admin or my main user), it just "redirects" to the login screen again instead of logging in.


    I'm running OMV on port 89. Updates are automatic by nightly cron so something maybe set it off.


    Any commands or info I can provide that might help troubleshoot the issue?


    The system is running well, I just can't seem to login to WebGUI from any browser anymore.

    [How-To] Fix full OS filesystem - GUI login loop
    Symptoms

    When you try to login to the GUI of OMV you are not being logged in, but the login page shows up again

    Check, if a full root filesystem is the problem
    ssh into your server (check the new user guide on how to ssh into your server) and run following command
    df df will show you the usage of each filesystem
    the output of df will look like this:
    (Code, 19 lines)

    The filesystem dev/sda1 which is mounted on "/" is the OS filesystem. The use of that filesystem is 100% --> the OS filesystem is full.

    Thanks, right on the money. Turns out my /var/lib/docker/overlay2 folder was crazy huge and sucking up incredible space. I'll next be researching ways to auto-prune this folder regularly so this doesn't happen again.

    The correct approach is to move the Docker storage folder off the OS disk and onto a data disk.

    Thanks, will research the steps to make this possible on an existing install - pretty easy I assume. Can't believe I set this up the wrong way when I did my fresh install unless this is what all the tutorials have you do.


    My OS disk is 120 GB and a dedicated SSD which I never thought would run out of space. Turns out dockers quickly suck up space since the old ones hang around for so long.

    RE: Move docker containers to non-system drive
    […]

    Yes that will basically be enough. The procedure is fairly straightforward.

    Stop the docker service
    (Code, 1 line)

    Make sure you have the full UUID for the nvme drive you want to move to

    Copy the folder (that way if something goes wrong, you can start over with /var/lib/docker
    (Code, 1 line)

    When it's finished go to the omv-extras docker plugin, and place the path in place of /var/lib/docker (ie, in the example above.. /srv/some-uuid/docker)

    CLICK SAVE (this is important)

    Once the new path is…
