Super weird situation, server is functional but I cannot access the dashboard and omv-firstaid yields "command not found"

As the title describes.

For context this is a server I have set up and running at a remote location, I cannot physically access it without hopping on a plane.

I can access my samba share over SFTP no problem works fine. I can login over Putty (I use private/public key) and it works fine, the server is there.

But if I teamview into a computer on the server's local network and attempt to access the web-GUI on the server I get the "403 Forbidden" error.

If I ssh into the server and attempt to run "omv-firstaid" the cli returns:

bash: omv-firstaid: command not found

Even if I sudo su and run the command as root I get that result.

So basically this server is working, but I cannot make any changes to the configuration over the web-GUI.

It'll be a while before I'm on location again and able to do something like reinstall the whole thing, and in the meantime my fear is a power interruption causing the server to power-cycle and it not restarting properly and me losing the use of the server until I'm back there.

Any way for me to deal with this issue 100% remotely? I don't even know where to start.

I don't know if this could be relevant but a couple weeks ago I had to run omv-firstaid to reset the online password (I forgot it).

root@raspberrypi:~# /usr/sbin/omv-firstaid
bash: /usr/sbin/omv-firstaid: No such file or directory

root@raspberrypi:~# sudo /usr/sbin/omv-firstaid
sudo: /usr/sbin/omv-firstaid: command not found

EDIT:

Also tried running the sudo variety from my user, not root. Same outcome as the above sudo attempt.

I will try that once I get home, but for the record, it can't have been an issue with the installation since as I mentioned above, I used the first aid tool a few weeks ago and it worked fine.

This might shine some extra light on things:

Seems to me like the last time I ran an update in OMV it went fully haywire? This is crazy.

Guess I'm leaving it running in its current "headless zombie" state, and do a full reinstall next time I'm over there.

I do find it extremely concerning that an update seemingly "suicided" OMV out of my server for some reason.
