Volume: System volume root's usage is 81%. This condition should not occur under normal conditions.
Hi Community, Running a ReadyNAS104-01 with firmware 6.9.2. Since a couple of days I have started getting messages from the NAS stating: Volume: System volume root's usage is 81%. This condition...
It turned out that the program on the NAS, MySQL was taking up the space.
The system root volume isn't the same as your data volume. It's a 4 GB partition on the disks that holds the operating system and the ReadyNAS application software. If it gets full, the NAS often locks up, and there can also problems with corrupted configuration files (when the NAS tries to re-write them, but that fails because the partition is full). Paid support can fix it remotely, but it is best to deal with the problem before the NAS locks up.
If you are running the AntiVirus service, I recommend disabling it, as it has been misbehaving lately and could be causing your problem.
What apps are installed, and what services are running?
Also, do you have an up-to-date backup?
Thanks StephenB,
We use the below services:
SMB, AFP, NFS, FTP, HTTP, HTTPS, SNMP, SSH
No apps installed.
"An up-to-date backup". Do you mean a backup off the NAS itself?

AntiVirus was not enabled then?
Try logging into the linux shell via ssh, and then check the current root usage.
# cd //
# df -h .
# df -i .
What firmware are you running?

Yes, the data volume of the NAS. If the NAS is used for primary storage, it should be backed up (RAID is not enough to keep the data safe).
Its a different story if the NAS is only used for backup - then it depends on your overall backup plan (how many backups you think you need, etc).
Firmware: 6.9.2
So it remains 85% full, and that needs to be fixed. Did you ever have any apps installed? Or install any linux packages via ssh?
You'll need to browse through the various folders, and figure out where the space is going. There are a couple of ways to do that, post back if you aren't familar with them. I suggest looking in /var first.
Several folders are actually mount points for the data volume - /apps, /data, /home, and /var/ftp in particular. You can see the full list by just entering mounts. Ignore those folders for now.
