Readynas 312

[MaartenProvo]

I have a ReadyNas 312 (v6.9.5) which has been getting slow over the last week. I run:

• Couchpotato
• Deluge
• Plex
• Resilio Sync
• Sickrage
• Home Assistant

I noticed in the logs an error 'systemvolume root usage over 85%  ...' I did some cleaning, using various post on this forum,  but I can't get it below 77%.  Performance has improved but still slow. Any ideas?

clamav is taking a lot of space (at least 15% of your OS partition), so perhaps consider whether you really need that.

/usr/lib/local is essentially empty on my system.  The stuff in there must have been installed by apt-get or the apps.

/var/cache is another place to look - it's taking more space on your system than on mine.

/var/lib also is taking up more space than my system.
