[Help] F4-210 will not expand volume

[atirrell]

Hello,

I'm helping my friend add more space to his NAS which I initially set up for him.
It is a F4-210 on version 4.2.40-2203011629 (4.2.44 seems available but no release notes since 4.2.41?)

Initially he was running RAID5 with 4x 6TB drives. He wanted to add a lot of capacity, so we went to the recommended Seagate 20TB drives. One of which was DOA and the replacement Seagate sent ended up being 24TB. But all 4 drives are detected and working fine, and synchronization is complete.

Now that that is all done, I am trying to expand the volume. This appears to be possible.

Here we can see there is available capacity.

Here I have clicked on the "Max" button to fill the volume.

After this, I click confirm. I see the spinning progress indicator for a moment as if it's doing it, it finishes, and then nothing.
Everything stays the same and the volume does not expand. I've tried it 3 times now and no luck. Not sure what to try next.
We are really hoping to be able to do this in place and not need to recreate the volume/redo his Plex Server.

The volume might be occupied by some service or application, preventing it from being temporarily uninstalled to increase capacity.
Please refer to this guide to release the occupation:

After releasing the occupation, try expanding the volume again.

I followed the instructions to a T.
Shut off all services that you can in the web interface.
Ran the terminal command.
The only response from that was "22524" -- whatever that means.


After this I tried expanding the volume in the web interface and still no change. It doesn't even tell you "Yes I did it" "No I can't do this" -- just a spinning progress ball and no change.

Can you restart NAS try again?

You can use the command 'ps -ef | grep 22542' to see what process or service with process ID 22542 is running and occupying the volume.
