if you have ssh access run
omv-salt deploy run avahi halt hosts issue systemd-networkd

Same result with and without sudo:

Perhaps I should try configuring the 20-openmediavault-enp1s0.yaml file as DHCP as you recommended, instead of static?

Read-only file system:

Your OS filesystem is mounted read only. This usually happens when there is a problem. I would: sudo mount -o remount,rw / but you need to look at the logs (like kern.log and sylog in /var/log/) to see why it is doing that.

I went to take a look at the logs, but even if I could find the error, I'd have no idea what it means or how to repair. For example, in the kern.log, the only thing my un-trained eyes could find was this warning in red at the bottom of the page:

[ File kern.log is unwritable ]

Here's what I got when I tried sudo mount -o remount,rw /:

Code

root@wdmch:~# sudo mount -o remount,rw /
mount: /: cannot remount /dev/sda19 read-write, is write-protected.

I know this may be a long shot, but could something strange have happened when I temporarily mounted my OMV's Linux HDD in my Windows 10 machine?

There was an option to 'Set default ownership and permissions of the mounted volume' (which I did not enable), when I mounted the HDD within the third party app 'Linux File Systems for Windows by Paragon Software'. Perhaps this was the culprit?

I also mounted the volume as 'Read-Write' in order to edit the files with Notepad++

Sure. That is a terrible idea so lots of bad things could happen.

Also not a good idea. I hope you at least used Unix line endings.

/dev/sda19

19??? Please tell me you don't have 19 partitions on that disk and this is just a typo...

OK, I'll have another crack at mounting and experimenting with settings.

Is this bad?

Look at the Edit -> EOL Conversions menu. Windows uses a CR LF for the end of each line. Linux uses just a LF. If you edit system config files and use CR LF, you will break things.

wtf... Why??? I also wouldn't use a 4TB disk for the OS.

You guessed it. I was on CR LF. I'll change and try again.

I believe the OS stuff is on a smaller 30 something GB partition, while the Data Volume is the 3.6TB partition. I just copy and paste things off the internet. Don't judge!

Please don't. If you are going to edit files on the OS drive, boot your system in Linux and use a Linux editor.

I will judge whatever you copy and pasted because it is terrible. Does making that many tiny partitions make sense to you?

I'm going to make you proud.

I feel you already know the answer. I've made a few changes, now rebooting...

OceanOver · May 3rd 2023

I changed the IP config files to DCHP.

While the router DID give the device a new IP address and the login page rendered (even with a Ctrl + Shift + R refresh), it is still rocking the '502 - Bad Gateway error'.

Let's rule out the IP stuff for now, as I feel it's working in it's current form.

As ryecoaaron has discovered, my issue appears to now be read/write focussed.

Are there any commands I can issue to force all my mounts/partitions to be read/write? (I know, this is becoming less OMV and more Linux related). I understand if we're moving too far away from this forum's purpose.

No. Linux is doing that on each boot to protect your system because there is a problem. That problem needs to be fixed. I don't know what that problem is though.

OceanOver · May 4th 2023

I've abandoned trying to sort out the write access issue.

I'm satisfied my original issue (re-establishing IP access to the device) was rectified with all your help. Thankyou dearly.

I'm fairly certain the mounting of the Linux HDD in my Windows 10 PC caused the read/write issue.

I've since unmounted the culprit (sda19), ran a FS checker and let it fix about 150 errors and rebooted.

The device no longer boots up. I'm admitting defeat and starting again. Thankfully nothing on the NAS worth saving.

Thanks again for all your help!
