I/O ERROR on file transfers from/to Readynas. What should I do?

[miogpsrocks]

I am getting some I/O ERROR on file transfers from/to Readynas 

Here are my specs. 

X-RAID

Model Readynas pro Firmware 6.9.2 data 2.85TB free ofi 18.17TB

Please advise on what I should do? 

Update: I tried to remove and add the Readynas address in the path against and it seem to have stopped the problem. In the past when I have received that error message it has usually referred to a bad hard drive. 

So nevermind. P.S. I'm not sure how to delete the question so I just added this update.

Hi @miogpsrocks

Seems that your Data volume is getting to 90% full which is not advisable. (2.85TB of 18.17TB free)

What are the errors you are getting? Can you send in your logs? You can use the guide on sending logs to moderators under my sig.

Many thanks!
