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
stephen, thanks for clarification. Fully agree, 100 bucks is nothing compared to loss of data.
I think I got the directory that sucks. I'm transferring surveillance pics and 100M mpgs via ftp and seems that they remain in /var/ftp that has now 266Giga. I think deleting all subfolders will solve the problem but better wait for the USB disk.:smileyfrustrated:
I haven't seen any setting in FTP protocol regarding directory or file deletion.

Be careful here. /var/ftp is actually a linux mount point. The on-disk space you are seeing here is really on the data volume (/var/ftp mounts the shares that have ftp enabled for the FTP server). It's not the cause of your full OS partition (which is only 4 GB in size btw).
Try remounting the OS partition as /mnt - that will take the mount points out of the equation and make the OS partition easier to search.
# mount --bind / /mnt
Sometimes files end up "underneath" mount points - particularly if you use USB backup jobs. So after doing the mount, look in /mnt/media first and make sure all the folders in there (USB_HDD_1, etc) are empty.
When done, you unmount with
# cd //
# umount /mnt
The umount won't work if you are in the /mnt folder (what's why the cd // command is there).
Ok, create an alternate view on the root partition called mnt and search for files that maybe underneath the radar. I mean, 91% of 4GB can't just hide somewhere.
Let me wait for the USB drive this week and once the backup is done I will come back and report.
Most the other system usage stories here had an issue with the ClamAV that seems to be not the case here.
