No WebGUI Login possible / Disk Full ;-)

    Hello, i need help if anybody can ;)
    Was hunting a Samba Access problem - and used "log level = 2" for my share. Forgot to set it back to 0. Now my sda1 is "full" at 100% and i cant find the huge consumed space. Even login in omv webgui is not possible because of low hdd space? I can access the machine via SSH. What options do i have?

    Found a old post here in the Forum, System Disk full. But thats weird to me...

    Code
    [21:59][root@Wasteland:/]# df
Dateisystem      1K-Blöcke     Benutzt   Verfügbar Verw% Eingehängt auf
udev               3983944           0     3983944    0% /dev
tmpfs               803188       92464      710724   12% /run
/dev/sda1         20118096    20100964           0  100% /
tmpfs              4015920           0     4015920    0% /dev/shm

    What is weird? There is this guide

    [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:

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

    This tip is from @Zoki :

    If you can't find the folder filling the filesystem

    Sometimes you see that you OS filesystem is full, but can not find which folder is filling your filesystem with the du command shown above. You may run into this situation, if some process wrote to the place where it expected a mounted disk, but the disk was not mounted at the time of writing. Now, while you are looking at it, the disk is mounted and you can not see the files on the OS file system, because the mounted…

    If you already know it is the logs, go directly to /var/logs and remove some of the .gz or .[1-9] files

    Thanks, but sda1 has 20gb and "du -xhd1" shows the "correct" 7.4gb. i delete about ~800mb logiles, but sda1 is still 100% full.


    ncdu -x


    Did you read what it linked, especially the second one?

    Sure, here is what i got...


    Code
    [22:46][root@Wasteland:/]# mkdir -p /mnt/rootfs
[22:51][root@Wasteland:/]# mount --bind /srv /mnt/rootfs
[22:51][root@Wasteland:/]# cd /mnt/rootfs
[22:51][root@Wasteland:/mnt/rootfs]# du -hxd1 /mnt/rootfs | sort -hr
1,8M    /mnt/rootfs
1,7M    /mnt/rootfs/salt
32K     /mnt/rootfs/pillar
8,0K    /mnt/rootfs/ftp
4,0K    /mnt/rootfs/dev-disk-by-uuid-5ef041e8-2d83-416e-9e6a-11918e09f833
4,0K    /mnt/rootfs/dev-disk-by-label-data

    So it is hidden somewhere on a different mount. Are you using folder2ram?

    Nope. But found myself a Hint on the Internet...


    Code
    lsof -s -- / | grep -e '^COMMAND \| (deleted)' | less

    Shows two 6GB large files, holded by rsyslog


    a "sudo service rsyslog restart" did the trick, diskusage back to 39% and WebGUI is accessable. But thanks! :)

    To find unlinked (deleted files) which are helb by other processes this is the easy command:


    Code
    lsof -a +L1 /
