Receiving "volume root's usage is 92%" message
I started receiving an alert last night stating "System volume root's usage is 92%. This condition should not occur in normal conditions. Contact technical support." Im not sure what is using up the ...
Ok so the issue is now resolved but just wanted to post the findings in the event someone else runs into this problem. The culperate was the ReadyNAS Replication which had a temporary issue and decided to store a failed replication job on the root volume. This data was hidden as it was being stored in the data folder (but on the root volume not the data volume). The fix was:
- To dismount the data volume using systemctl stop data.mount
- Remove the folders within data.
- Then remount the data volume using systemctl start data.mount.
Follow these steps at your own risk, if your not comfortable reach out to netgear support to fix the issue.
Big thanks to Danthem for all of his help and to Stephen B for his suggestions and input.
The root volume is NOT your data volume. You can't see the root volume unless you are using ssh. It is only 4 GB in size, and is the OS partition where linux runs.
You likely have free chat support - if so, I suggest you use it. A full OS partition can brick your NAS. (If it does, support can still fix it w/o data loss).
I looked around for a chat option and didnt see one. Im not sure if it will be covered as it is a few years old at this point.

If you purchased new from a official reseller after 1 June 2014 then you have lifetime chat. http://kb.netgear.com/app/answers/detail/a_id/26066/~/readynas-support-and-warranty
If you don't have chat support, support will likely charge to fix it. The US cost for per-incident support was $75 last I heard.
If you are comfortable with linux commands, then you could attempt to fix it yourself. I suggest updating your backup first.
Ok thanks for the reply's both of you. Currently trying the chat feature now that I found it and I will update this post if it gets resolved or not.
As expected it was purchased just shy of June 2014. You are correct with the pricing of $75 per incident. Do you have any suggestions on what to look for in the terminal. Upon review nothing stands out as taking up large amounts of space. Checked the log files to see if any of them went out of control.
