ReadyNAS 314 lack of disk space

ReadyNAS 314 lack of disk space

Hello, we have a ReadyNAS 314 that was recently updated to firmware 6.5.0. Ever since the update the device will intermittently start to behave as though it's out of disk space. The device's dashboard shows that it has over 4 TB free. Restarting the device resolves this for a few hours or a day. We do not use any snapshotting but we do use the ReadyNAS Replicate service to replicate shares to another 314 unit. The replication process seems to create snapshots temporarily and the logs indicate they are successfully removed afterward.

 

I've disabled the disk spin-down setting thinking it's failing to spin-up after idling but that didn't make any difference. Any other suggestions or ideas would be appreciated.

 

Thank you,

Mike D.

Can you describe the symptoms?

Re: ReadyNAS 314 lack of disk space

Attempting to save anything to the device will fail. The device is mostly often used a repository for scanning, so the most common symptom is that a scanned item is simply not available. Our scanners don't give any specific reason for the failure. Existing items may still be accessed, as least for viewing.

 

When I browse a share through the admin web interface and try to drag and drop files I receive an error message about lack of disk space. I didn't think to save the exact wording and can't reproduce it because the device is working properly at the moment.

It might be the OS partition that is out of space.

 

If you have support (most RN314 owners do have free lifetime chat support), you can contact Netgear.

 

Or you could enable ssh, and check for fullness with 

df . -i

df . -h

 

If you haven't done this before, you log into the NAS using putty (windows) or terminal (mac).  You use "root" as the username with the NAS admin password.

The RN314 uses BTRFS for the 4GB root volume so checking for inode usage (# df -i ) is pointless.

 

What does the top of your BTRFS.log look like?

Good point.

Here's the beginning of the btrfs.

That looks like a full OS partition.  4 GiB used of 4 GiB total.

 

What apps (if any) do you have installed?

That's the space allocated. That doesn't mean the allocation is full.

 

Can you send in your logs (see the Sending Logs link in my sig)?

Re: ReadyNAS 314 lack of disk space

Thanks fellows, but while chatting with Netgear support the device took a turn for the worse. Active Directory integration failed and I ended up calling and opening a case. It was escalated to level 3 and they're handling this now. I don't yet know about the disk space issues because the integration failure is much higher priority and possibly caused the disk trouble to begin with.
