System volume root's usage is 84%. This condition should not occur under normal conditions.

Question

Hi,
&nbsp;
I've seen many instances of this on the web, but no clear instructions on how to fix it.&nbsp; At the moment, I have no apps that are loading (but they should), and my system says no apps are installed (but they are).&nbsp; I hope this is just a function of having a somewhat full root volume.
&nbsp;
Any suggestions would be greatly appreciated.&nbsp; I'm somewhat of a newbie, but can follow instructions.&nbsp; I've got SSH enabled and can access the system if needed.
&nbsp;
I do not want to do a refresh as I've got way too much data on this system.&nbsp; Al the really important stuff is backed up though.

Hi NTGR-OPS

&nbsp;

Support can definitely help you out free up OS volume without touching the Data. I wouldn't recommend doing it yourself if you are not comfortable using SSH but others might be able to provide you instructions. If you have full backup of your data you can do a Factory reset, only if you want to.

Hope this helps!

I'll give that a try.&nbsp; Appreciate the quick response.

I contacted support right away and still waiting for someone to assist with actually looking at the system.&nbsp; Thyey took my details and all, but details and ETA seems to be slow.&nbsp; I've just asked for an update again.&nbsp; Hopefully&nbsp;3 days down is long enough.

Well, after a week of trying to get chat support, someone came in last night and "fixed it".&nbsp; I now have a system opening up in safe mode with no active raid array and cannot access any data.&nbsp; I'm very disappointed at the support I received over this service and am looking for them to try and "save" the data on the system.
&nbsp;
It has been a terrible experience and the folks that were on chat seemed unfamiliar with what to do, even after escalating to "level 3".&nbsp; A complete mess.

These kinds of issues are usually following the same steps:

Identify what's filling up the 4GB root volume.
Remove the data that shouldn't be there (either delete/move to data volume)
make config changes/firmware update (if needed) to stop it from filling up again for the same reason
check for config corruption (can happen if the root volume gets full)
verify it comes back up fine after reboot. If not check again to find out why that didn't happen and fix further issues.

In extreme cases formatting the 4GB root volume might be needed and there's another set of steps to do that properly.
&nbsp;
It booting into safe mode would seem to suggest that the 4GB root volume might be completely full or can't get mounted for some other reason or there's some other issue leading to the RAID not being mountable.
&nbsp;
The chat support team you're speaking to would be level 2. Advanced Level 2 (possibly), Level 3 or maybe even engineering (though there'd have to be a widespread issue or more serious issues encountered for it to get up that high) would be needed to attempt to fix a full root volume.
&nbsp;
In safe mode you can enable Secure Diagnostic Mode under System &gt; Settings &gt; Support (especially useful if the NAS is at a remote site) or you could boot back to tech support mode for them to have another look. Either way would work for them.
