ReadyNas102 - Volume Root Usage

Version 6.10.7

Only apps on RN102 are iDrive and Resilio sync. I removed iDrive last evening. At beginning of 2022 I noticed my iDrive was not backing up from RN102. I reinstalled it (or tried to install an updated version, not sure which). I am now getting this: "Volume: System volume root's usage is 83%. This condition should not occur under normal conditions. Contact technical support." I found a post about removing the clamav.tmp files, so I did that. I have downloaded all the system logs, but I have no idea which one would actually be informative. I went through to try to figure out what the root space is being used by, below is what I came up with. My primary goal is to get the root usage down. After that I would like to get iDrive working again (because I am paying for the storage but nothing is being backed up). I am not good at this stuff, but will read whatever anyone responds with carefully, and try to follow the directions. I appreciate whatever assistance anyone can offer. Thank you in advance.

Yes, it's definitely /var/log.

Try going deeper, that would help sort this out:

root@NAS:/var/log# du -h /var/log
0       /var/log/news
112K    /var/log/apt
0       /var/log/fsck
436K    /var/log/frontview/backup
3.1M    /var/log/frontview
0       /var/log/samba/cores/nmbd
0       /var/log/samba/cores/smbd
0       /var/log/samba/cores
752K    /var/log/samba
3.2M    /var/log/apache2
2.3M    /var/log/readynasd
39M     /var/log/journal/6c58f1a31323453ea933c21fd1d53cbe
39M     /var/log/journal
0       /var/log/clamav
0       /var/log/audit
50M     /var/log

Anything in /var/log/clamav can be safely deleted, the RN102 no longer has the AV service.

I added this screenshot of some other directories. It looks like my "apps" and "var" are quite large, but I don't know why that would have anything to do with my root usage. Anyway, I thought this might help someone with the diagnosis. The messages definitely started about the time that I "reinstalled" the iDrive app, so it seems like the two things are related.

  apps is a mount point (the actual storage is on the data volume), so that is not a concern.
  
  var on the other hand is part of the root file system, and it is too full. Here is what mine looks like (also an RN102, which is running 6.10.7 firmware)
  
  root@RN102:~# cd /var root@RN102:/var# du -d1 -h 2.3M ./ftp 8.0K ./www 92M ./backups 16K ./spool 70M ./cache 9.6M ./readynasd 4.0K ./local 4.0K ./mail 4.0K ./tmp 4.0K ./opt 4.0K ./cores 16K ./netatalk 243M ./lib 59M ./log 475M . root@RN102:/var#

I very much appreciate your assistance Stephen B. You are on a ton of these posts and it's great that you help so many people with this stuff, it's extremely generous of you. Thanks again.
