System volume root's usage is xx%. This condition should not occur under normal conditions. Contact
ReadyNAS 104, latest firmware (6.9.5), 4,17TB free of 5,44TB, default antivirus, NO installed Applications, enabled sevices: SMB, NFS, FTP, ReadyDLNA, Rsync, UPnP, HTTP, HTTPS, Antivirus.
Used for data 70 % for DLNA (multimedia), 30 % for backup of important data, total only 23 % of capacity is used.
I have acces via Web Admin Page only, no knowledge of linux OS.
Problem - I got the message: "System volume root's usage is 84%. This condition should not occur under normal conditions. Contact technical support."
It is somewhat funny, because I do not have acces to the root and there is no way how to contact "technical support". It seems that maybe there are some residual files (firmware upgrades, antivirus definitions upgrade and so on) in system root and this is general problem of NetgearOS. As a normal user, I do not have access to the root and cannot influence what is stored in the root. I just tried to delete Logs (WebAdminPage>Logs: ClearLogs), but without any change. After restart of NAS I got the the same arror maessage again.
Please, how to solve this problem? Thank you very much.

You certainly can contact paid support via my.netgear.com (assuming you are the original purchaser of the NAS) - though they will charge.
I suggest turning off antivirus, and see if that helps. Netgear will be dropping the antivirus service on the RN104 anyway in the next release (6.10.0).
Hi Stephen, thank you for your suggestion. I turned off antvirius, after restart it sends me again the same error message (just 1 % mor then before).
I have no problem with paid support,. I have no problem to pay for my mistakes, but I have problem to pay for Netgear mistakes in their SW!

I cannot agree with this statement more. The lack of NetGear official support of this NetGear caused issue is very troubling. Are you listening NetGear...?
Hi,
I had exactly the same problem on my RN102. Since March the 5th the antivirus didn't update any more. On March the 17th I received the error message "System volume root's usage is 84%".
After 4 hours of investigation and research I think, I found out the problem. According to the information about OS 6.10 the newest version of the antivirus "ClamAV" is too large for the RN100-series.
I connected to the NAS via SSH and tried to update the antivirus manually by using "freshclam". The download of the latest databases worked fine, but the update of the antivirus ended in an endless loop and the root usage increased to 94%. After some research I found out, that the antivirus makes for each update a temporary directory located at /var/lib/clamav beginning with "clamav-..." and ending with ".tmp". Each of the directories has about 133MB. Each time the antivirus updates, the downloaded data are stored in such a directory, but if the update fails, the directory is not removed! So after about 10 days the root-volume is filled up and the system crashes.
My solution (usage on your own risk): remove the temporary directories mentioned above in /var/lib/clamav (BE CAREFUL - wrong deletion can destroy your system!). After this deactivate the anti-virus (else the next update will also fail and the filling up starts again). Restart the system to be sure, that all tasks are ended. On my NAS this worked.
Thanks for letting know, asimb.
Hi asimb, thank you very much for your valuable informations. But how do I get into root? I can only see the directories I created myself. I only have access through ReadyNAS Admin Page (via local www of NAS).
Thanks
First of all you have to enable SSH on your NAS admin-page (description how to do see https://kb.netgear.com/30068/ReadyNAS-OS-6-SSH-access-support-and-configuration-guides "Enabling SSH access for root using password authentication"). Then you have to start SSH on your windows computer using "ssh root@<ip>.<ip>.<ip>.<ip>" (ip means the ip-adress of your NAS). The password is your admin-password.
then you have to type "cd /var/lib/clamav" and then "ls -la". Then you should see some entrys beginning with "clamav-..." and ending with ".tmp". Please check this.
I appreciate the solutions above but have yet to be able to get my RN104 to co-operate to clean the tmp files. I will persist.
However, 6.10.0 has been released and I installed it yesterday. I had the faint hope that Netgear might be clever enough, when removing anti-virus in 6.10.0, to also organise to sweep any of the offending files out and solve the problem without me having to still do it manually. But no! If it's not techncially possible then fine but I have the sneaking suspicion that it is not impossible?
Come on Netgear - you stuffed it up in the first place.
Back to trying to do it myself. I can't seem to get in because of a publickey issue.

Can you explain more about this issue?
Hello Stephen B, when trying to log in using Windows Powershell using the command ssh root@XXX.XXX.X.XX I get the following message:
Permission denied (publickey).
Sorry I am not an expert and feeling my way.
At 8.00 I receive a message from my ReadyNAS 314 "
Användningen av systemvolymen root är 81 %. Det här tillståndet brukar inte uppstå under normala förhållanden. Kontakta teknisk support." (the same as stated in a number of issues below).Translated i say "System volume root's usage is 81%. This condition should not occur under normal conditions. Contact technical support".
My NAS has been upgraded to latest OS 6.10.2. The problem started in the previous OS 6.10.1.
My REadyNAS is configured with 4x4000GB discs Running as RAID5. The usage is 9.42 TB free of 10.90 TB.
How can I clean this up?
It looks like a system fauls. Why wasn't it correcte with the upgrade to latest OS?
Best regards
Lars-Olof
loha, it is bad practive to "piggy back" on onther posting, as your situation may not be the same and answers meant for one poster get confused with those intended for the other. Please open your own thread.
That said, it's not the OS that typically creates that problem, it's an app. And doing OS updates can make the situation worse because the NAS lacks working space for the upgrade. There are dozens of postings that address this issue, perhpas you should read some before asking the same questions over. The search function of the forum is abominable, use Google instead.
