System volume root's usage is 89%. This condition should not occur in normal conditions.

Hi All,

 

I keep receiving an error message "System volume root's usage is 89%. This condition should not occur in normal conditions. Contact technical support."

After some research, I found


root@nas-34-B2-24:~# df -h

As someone who hasn't used a ReadyNAS or linux system, I'm not too familiar with the system. From what I've read, there is an issue with the log files taking up too much space. I want to clear out those log files but haven't been able to find clear instructions as to how. Could someone point me to some instructions?

I did run the du command on the md0 file.

root@nas-34-B2-24:/dev# du -h md0
0 md0

 

I don't know why it would return 0.

It's not really a file, its a device.

 

You need to look in the OS folders.  /var/log and /var/cache are the places to start.

 

What apps do you have installed?  Have you made any changes to the system with ssh?

Hi @StephenB,

 

What would I be looking for in the OS folders?

 

As for apps, we have LogAnalyzer, Plex Media Server, and ReadyNAS Photos II.

 

I'm not sure if we've made any changes with an SSH connection. We have two NASes. I have attempted to install Crashplan on one of them, but not this one.

@StephenB When you say look at the OS files, I'm not sure what to look for or what to do when I've found it.

The problem won't be in Apps, as that folder is actually remounted from the data volume.

 

Probably the safest option for you is to contact support (ask for "per-incident" support, that is cheaper than a service contract).

 

But basically you are looking for large files that are taking up the space.  If you want to continue on your own, you can compare the folders on your two ReadyNAS.

Hi @mdgm-ntgr,

 

When I went to the support page and enableed Secure Diagnostics Mode it simply gave be a port number. Just fyi, the ReadyNAS associated with this account is not the one having these issues.

Re: System volume root's usage is 89%. This condition should not occur in normal conditions.

I am having a similar problem after installing the Resilio Sync 2.4.4 application and uninstalling the old BitTorrent Sync app. I get:

 

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

 

Also, my drive mapping has become flaky, to the point that most won't map at all, or take a very long time.

 

I have SSH enabled, but don't have any idea how to actually use it on WIndows. Any help or direction would be appreciated. Regards,

 

Rob.........

You need to check for what's using a lot of space on the 4GB root volume.

Download putty from here: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

 

Then launch it and connect to the NAS IP address.  Use root for the username and the nas admin password for the password.

 

Start by entering

df -h

 

and post the results here.

 

What ReadyNAS model do you own, and what firmware is it running?

Re: System volume root's usage is 89%. This condition should not occur in normal conditions.

Thanks for the reply @StephenB. Since this was a business critical issue for me, I paid for a tech support call from NetGear to fix it. Turns out that the default settings for the Resilio Sync app creates a folder 'Resilio Sync' in the /root folder  instead of the /data folder (where it should be). Then when I linked to other devices, it tried to replicate all of those remote synced folders there.

 

The solution was to delete the '/root/Resilio Sync/' folder (I had NetGear do that), then change the default folder in the Resilio Sync app to a folder under the /data folder and manually reconnect my synced folders.

 

I'm not savvy enough about the SSH commands to go that route, but thanks for the suggestion. Regards,

I'm experiencing the same Resilio issue now.  I'm able to ssh into the device.  From there I'm not sure where to turn.  I want to delete the Resilio directory and start over.  I've removed the app via the GUI but that does not delete the directory.  Its a new unit so I'm not worried about crashing it.  Thanks in advance.

I think you can just delete the Resilio folder

 

Are you seeing a lot of space usage in /var/cache and /var/log?

You could of course do a factory reset, and rebuild everything from scratch.  Overkill, but if you aren't in a hurry it has the advantage of cleaning out everything.

I did a restore as I couldn't figure out how to delete the bloated directory via SSH.  Now I'm getting messages warning me that less than 20% of media capacity is free.  What is that?  I created a directory on a new share within the 2TB volume.  The sync share is less than 70GB.

That suggests that the 4GB root volume is getting full.

 

Sounds like you've done some of the same things that you did last time.

Re: System volume root's usage is 89%. This condition should not occur in normal conditions.

I thought the same thing but if that were the case it would be full as the Sync share is 70GB.  Also when the root dir was full the error was different.

I thought I had solved this issue with a factory reset of the NAS.  Now instead of "root" volume filling the system states, "Less than 5% of volume media's capacity is free. Performance on volume media is degraded. To improve performance, you must add capacity."

 

Media capacity?

Re: System volume root's usage is 89%. This condition should not occur in normal conditions.

Tthere is an issue with the antivirus temporarily fills up the volume. In this situation, the root volume is called 'media' in the logs. You can find multiple threads about this here. Workaround while waiting for the fix in future firmware:

1. Gracefully reboot the unit.

2. Disable he antivirus.

3. Gracefully reboot the unit.
