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

Hi all

I've found a few miscellaneous posts about similar problems but none that seem to relate here.

I'm getting the log error:

Volume: System volume root's usage is 92%. This condition should not occur under normal conditions. Contact technical support.

This morning it was at 82%... increasing steadily since then. It now is marked as volume critical.

I don't have any apps installed. I tried disabling antivirus and rebooting and then turning it back on as another post suggested. Still no go.

I paid for some support and have been calling in and raised a case but after several hours there doesn't seem to be a solution and the % is rising.

Any ideas?

Hi I seem to be having the same issue.  I'm running firmware 6.9.5.  I've tried ssh to the device and using the command df -i i get the following in putty:

As far as I can tell from this I don't seem to have a problem as the highest usage is 23%.  Can anyone provide any better checks for diagnosis?  I'm not an SSH expert so step by step help welcome!

df -h gives

so clearly the /dev/md0 bit is the problem.

Perhaps turn Antivirus off and leave it off.  Netgear is dropping it for RN100s in 6.10.x anyway.  The RN100s only have 512 mb of RAM (compared with at least 2 GB in the other OS-6 platforms).

There is a guideline here that gives some steps for diagnosis:  https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/RN314-FW-6-7-1-root-partition-full-...

You do need to be careful about deleting files, especially if you don't know what they are for.  It'd be best to make sure your backup is up to date first.

I've then done:

mount --bind / /mnt
du -d1 -h /mnt
umount /mnt

This gives:

 

So the problem seems to be either the 230M /mnt/usr, or the 487 /mnt/Adele

Adele shouldn't be there at all - do you have any idea what it is?  It's certainly part of the puzzle (500 MB).  If you have another copy of it's contents you should delete it.  If not, you can copy it to an existing share on the data volume and then delete the copy in the root.  Later on you can put it where you really want it. 

But the big problem is /var (2.6 GB)  That's about 2 GB more than it should be.  So try the mount again and descent into /var.  See if you can find where the bulk space is going.  When you find the folder, look at the actual file sizes (ls -al), since it might be just one or two files.

i am having he same issue, the big space user on /var/ is in /var/lib/clamav.

There are folders names clamav-*.tmp. these use up over 3GB aand are likely why I am running out of space. is it okay force a delete of those folders? I have ssh access, but not sure how as admin to force the delete (I get permission denied.)

[ReadDude]

So, just to answer above, I thought the folders where held open by clamav, but it was justs permissions, I used sudo to force root permissions to delete the folders and got back over 50% of my /dev/md0. So it looks like a bug in the anti-virus.   my fix was via ssh and using shell commands. experts here can describe so I don't leave around a mess or dangerous instructions.

 I am now keeping anti-virus off all the time now....

I think you are right. Refer also my post at: https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/System-volume-root-s-usage-is-84-Th...

StephenB - thanks you are right.  No idea how Adele got there but it was her album 21!  Deleted now.

/var proved to be the anti-virus so cleaned that up and turned it off.

Many thanks.

Thanks asimb - that sorted the problem.
