Volume: System volume root's usage is 95%. This condition should not occur in normal conditions.

[Jaroslaw]

Hello was reading similiar topics and have not found an answer.

RN20400 RAID 5, 4x3TB

Data 4.19TB

Free space 3.98TB

running only antivirus, yet recently started to get:

Volume: System volume root's usage is 95%. This condition should not occur in normal conditions. Contact technical support

You can check if that data is important e.g. using commands such as

# ls -laR /media/USB_FLASH_6

and if not you can delete it using the rm command. If it is important and you don't have another copy of it you should copy it to the data volume before deleting the copy from the root volume.

Download the logs from the GUI and post here the section containing "df -h" at the end of the file volume.log

Do you know how to use SSH?

[Jaroslaw]

Nope, sorry never used it and afik it's not enabled on my nas

[Retired_Member]

As a temporary solution/workaround just switch off the Antivirus service and reboot to see, whether its getting back to normal. If it helps, keep it disabled and wait for the fw 6.7 to be released.

OK as a temporary solution I will switch off the antivirus engine and observe. So far I switched off UPNP with Netgear Cloud. , ITunes, SNMP, SSH and Rsync are disabled by default although I was trying to get iTunes running last night, strange.

Thanks

No, please, do not send the logs. Instead, on the admin webpage go to System/Settings and in the services section disable Antivirus by clicking on the concerned button. Make sure, that you keep HTTP, HTTPS and SMB enabled.

I will do that, thanks!

So here is the current sittuation

If there is no need for AFP (apple macs), NFS (genuine Linux) or FTP (data transfer using that service) disable all three and reboot.

So for MACs,Wins and Android which ones would you recommend that I leave running, please?

Just SMB?

[Retired_Member]

I would go just with SMB. My Android devices have no problem to access the nas volumes as shares on the windows network. I have no experience with macs, but it should be a standard situation for them to access a share on a windows network. If you definitely do not need FTP, switch that off first and see how it goes before switching off anything else.

NEVER switch off HTTP and HTTPS, please!

[Jaroslaw]

Thanks,

SMB does the trick on Macs too.

Thanks!

Unfortunately even after switching off antivirus and "spare" protocols:

System: ReadyNASOS background service started.

Volume: System volume root's usage is 95%. This condition should not occur in normal conditions. Contact technical support.

Volume: Less than 5% of volume media's capacity is free. Performance on volume media is degraded. To improve performance, you must add capacity.

Sat Mar 18 2017 19:19:05

System: The system is rebooting

[Jaroslaw]

Above 50% of capacity is free....

Downgraded the OS to 6.60 still same issue

[Retired_Member]

I think to downgrade to 6.6.0 might not have been a good idea according to the 6.6.1 release notes

https://community.netgear.com/t5/ReadyNAS-Firmware-Release-Notes/ReadyNAS-OS-6-6-1-now-available/td-...

I fear you need help from one of the NETGEAR moderators now. This is beyond my capabilities. Sorry for not being able to finally help you fixing this.

"volume media" is the root volume, the OS volume.

The procedure for the AntiVirus issue was reboot, turn off AV, reboot.

If you still have issues afterwards, please paste here the extract I asked earlier ("df -h" section at the end of volume.log)

That's the info I'm looking for:

So the OS volume is indeed completely full. Next steps require SSH.

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

These are non-intrusive commands, but do NOT do that yourself if you don't feel confortable with it. You should contact NETGEAR Support if necessary. Or see if a NETGEAR Moderator, like mdgm, can help you clear the situation.

Thanks M8,

I will do my rapid course on SSH...

What is the reason for such sittuation, would you know? It just started to happen out of a blue...

[Jaroslaw]

And now...how to pick up the pieces and clean all that mess, please? Are there any tools to do so, maintenace plans for future?

[jak0lantash]

Why did you do a 'reboot' from SSH?

That's not the right way of rebooting the NAS from CLI. Please don't do that.

It appears there is some data in /media, maybe something like a backup job to a USB device started before the USB device was propely mounted.

Can you do the following (don't have any USB device plugged in):

du -d1 -hx /media

[Jaroslaw]

WOW,

you are GOD to me:

12K /media/._share

2.9G /media/USB_FLASH_6

24K /media

Why is that there? Have not done any backups recently...very strange. Is there any tool to free up that space, please?

And BTW I will not reboot under ssh anymore!
