RR2304 - System volume root is 91%.
4x2TB NAS with current OS 6.10.2 reports the same warning message on 91% usage as many other users were facing already. According to the info here I have - turned on SSH Service - turned off AntiVi...
Finally I could free the OS partition, no more warning messages, thanks for all the help.
I add a small summary of my steps for others that may have a similar problem.
1. Preparations in NAS settings
a. Activate SSH Service with password: System > Settings > Services
b. Turn off AntiVirus
2. SSH login (Windows 10)
ssh root@<nas-ip-address>
Password: NAS Admin password
3. File search
a. Search for any large files >200MB: find /var -type f -size +200M
b. Look into Antivitus definition directory for any temp files: cd /var/lib/clamav
ls -lsh
c. Look into media/USB_HDD_1 (that is my 8TB USB connected HD) folders for any files
Result 3a-c: no large files, no temps, nothing peculiar in USB_...
Some threads can be found here where users had to delete the /clamav tmp files, not in this case.
4. Mount the root partition as mnt to eliminate directories from listing that actually point to the data partition
a. mount --bind / /mnt
b. ls -lsh -> found many chunk-0000x files in the root directory (StephenB telling that this is from PLEX transcoding)
c. Delete files: rm /chunk-00*
Another ls -lsh: all chunk deleted and reduced partition usage from 3,5G to 1G
d. cd //
unmount /mnt
e. Turn on AntiVirus in NAS settings

I can see a lot of chunk-0000x files all from the same date.
Those are generally from plex (aborted transcoding). So just delete all of those.
