System volume root's usage is xx%. This condition should not occur under normal conditions. Contact

Hi, today i ran into the same issue and solved it with your described steps.

- Enable ssh service and the ssh login permission via accounts > user

- Login e.g. Putty and switch to root via: su -

- Check the size of the root-fs via: du -hsx /* | sort -rh | head -10

(you'll get the following output)

root@STORAGE:~#
du: cannot access '/proc/17259/task/17259/fd/3': No such file or directory
du: cannot access '/proc/17259/task/17259/fdinfo/3': No such file or directory
du: cannot access '/proc/17259/fd/3': No such file or directory
du: cannot access '/proc/17259/fdinfo/3': No such file or directory

- change directory to /var/lib/clamav

- stop the following clamav services via: systemctl stop ...

-rw-r--r-- 1 root root 565 Oct 9 21:53 clamav-daemon.service
-rw-r--r-- 1 root root 204 Oct 9 21:53 clamav-freshclam.service
-rw-r--r-- 1 root root 156 Oct 9 21:53 clamav-freshclam.timer
-rw-r--r-- 1 root root 499 Oct 31 05:17 clamav-init.service

- delete the temp-folders and (maybe the *.cld-files) via : rm- rf

- disable the clamd-services if needed
