Interesting. Just checked on my system. I had upgraded from OMV 4 to 5. /etc/resolv.conf was not symlinked. There is no resolve directory within /run/systemd. I ran the omv-salt command, but no change. /etc/resolv.conf just contains my (standard) nameserver entry directly.

The systemd-resolvd service, which would create /run/systemd/..., is only enabled by default on Buster installations. Also this symlink does not exist on systems upgraded. Further enabling and starting the service does not create the link. And, as mentioned somewhere in this thread, with systemd one is expected to use 127.0.0.153 as DNS server. So there are various ways how to deal with it. To enable and start the service on an upgraded system one has to do:

sudo systemctl enable systemd-resolved

sudo systemctl start systemd-resolved

Then one can either link resolv.conf

sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

OR put the systemd DNS server into it:

echo "127.0.0.53" | sudo tee /etc/resolv.conf

The relevant configuration file /etc/systemd/resolved.conf can also contain specific DNS settings.

sytemctl

Just to tell you, this is a typo.

You should write: systemctl ....

I tried you commands but it does not work

It seems the file resolv.conf does not exist and it is not possibile to recreate it
