System Disk is full

Did you clear the cache using omv-firstaid as well?

Maybe you should ask this in the UrBackup forum

How did you specify the path? With /sharedfolders/.... or with /srv/dev-disk......?
You should use the srv version, but not sure if this has an impact on the behavior you experienced.

its not as good as OMV forums!

So let's challenge the OMV forum; Does anybody have an answer?

While I wait for that answer, I'm now getting this error message when trying to apply config changes:

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; omv-salt deploy run avahi 2>&1' with exit code '100': ERROR: The state 'avahi' does not exist

This looks like a faulty installation.

Try to reinstall with

# apt-get install —reinstall openmediavault

There are two "-" in front of reinstall.

It is --reinstall not -reinstall

I am quite sure that settings will persist.

Thank you a lot. It was exactly this happening and you helped me figure out the problem in really much less time than it would have took! I now created a script that first tries to read a file that is ONLY in the mounted drive so that if it isnt, the rsync will not happen.

That is clever. Another option is to store the script on the remote server, and launch it using a cron-job (or a Scheduled Job) on the local server that also will run the script. Then the script itself is used to flag if the remote server is available.

An advanced extra option (that I haven't tried) is to create a "mirror script" in a subfolder to the mount point (when nothing is mounted) with the same path and name as the remote script. Then this local mirror script will be executed if the remote server is not mounted, rather than the remote script. For instance to mount the remote server and/or notify that it is not mounted.

When the share of the remote server is mounted then the "mirror" script is not visible and the normal "remote" script is executed.

Other option that should work:

Use mountpoint to check if the given directory is a mount point.

If the filesystem is not mounted, the directory will either not exist (normal case) or will not be a mountpoint.

Actually rsync in OMV should check if the filesystem is mounted. The code in /var/lib/openmediavault/cron.d/

has following:

if ! omv_is_mounted "/srv/dev-disk-by-label-xxx/" ; then
    omv_error "Source storage device not mounted at </srv/dev-disk-by-label-xxx/>!"
    exit 1
fi

for source and target. BUT on my system (2x OMV5 and 1x OMV6) omv_is_mounted is not available.

votdev could you bring some light in this? Am I mistaken?

EDIT: Got it, it is in the helper-function

# omv_is_mounted <mountpoint>
# Check if the given mount point is mounted.
# @param mountpoint The mount point to check for
# @return Return 0 if mounted, nonzero otherwise.
omv_is_mounted() {
        if ! mountpoint -q "${1}"; then
                omv_debug "omv_is_mounted: Mount point '${1}' is not mounted"
                return 1
        fi
        omv_debug "omv_is_mounted: Mount point '${1}' is mounted"
        return 0
}
