Volume: System volume root's usage is XX%.
Since adding new HDDs and resyncing, I've been getting the following error message: Volume: System volume root's usage is XX%. This condition should not occur in normal conditions. Contact techni...

You can get an idea using the du command, but the du command isn't designed for BTRFS so you get a rough idea.
It should be mounted before it starts.
There are other things like mysql taking up space on the root volume.

Does this mean I should just delete mysql?
Sarcasm aside, I don't know what to do. Via SFTP I just deleted some "uemediaserver" folders that I suspect are no longer in use, and I deleted the "Mobile Photos" library from my Plex Media Server (along with all the photos it contained) and the alert messages stopped. So I guess it's at least reduced to non-critical levels.
The du command is great, but I don't even know how to execute it properly in this case.
And if I move mysql and LMS to data, will they now appear as shares?

I can see your support case has been escalated. You are probably best to wait for the support agent to take a look and advise on the situation.
The Plex Media Server app data should already be stored on the data volume. - nsneDec 16, 2015Virtuoso
Yesterday Netgear Support e-mailed me the following instructions:
1. Turn off the RN314
2. Remove disk 2,3 and 4 in the chassis and keep just disk1 (HDDs from RN104)
3. Reset the RN314 to factory defaults with only disk1
4. Once the NAS boots up normally, go to storage and disable XRAID by clicking on the icon
5. Once XRAID is disabled, insert all the 3 disks we took out earlier in order (disk2,3 and 4)
6. Then go to Settings and enabled Support Diagnostics and provide me the 5-digit codeGood thing I queried some of the details. It was for an entirely different case. I'm not sure what's worse, silence or misinformation.
So I took matters into my own hands and began shifting Logitech Media Server files out of rootfs because LMS has definitely been identified as too space-hungry. I need to move my mysql directory, too, but that's tied to Netgear's Contacts and Calendars Server (i.e., Baïkal), which cannot be switched "off" from the GUI, so I have no idea how to kill it so I can move the files to /data.
The other thing is that I have no idea how to assess the current size of rootfs, since it's not appearing when I use the "df -h" command. This is the output:
root@XXXXXX:~# df -h
Filesystem Size Used Avail Use% Mounted on
tmpfs 10M 4.0K 10M 1% /dev
/dev/md0 4.0G 2.4G 1.3G 65% /

tmpfs 2.0G 5.8M 2.0G 1% /run

/dev/md127 13T 4.9T 8.0T 38% /apps
/dev/md127 13T 4.9T 8.0T 38% /var/ftp/Backup [...]
What am I doing wrong? Where's rootfs?
