Can you post your entire diagnostics.  Also is there a specific share or path or program that you're talking about here?

Thanka for reply, here comes the diagnostic file

What version of Unraid are you running ?

I see things that I never saw in my limited experience (<2y).

So you're running an ancient version of the OS (6.1.9)  There were some issues with the file system on both the cache drive and disk 1 (most likely due to the power cut)

 

To be safe, I would run the check filesystem against both of them.  

 

I would also seriously consider upgrading the OS to 6.9.2+ as there is a multitude of security and OS enhancements (not to mention diagnostic improvements that help with problems such as this)

 

I'm not sure however if the files that disappeared due to the power cut will be recoverable.  Every computer should have a UPS attached to it and set up to do a clean shutdown in case of a power failure, as this is where filesystem problems, corruption etc all come from

 

 

On a side note, after all this has been worked on, you should also consider changing the file system on your REISERFS drives.

There are guides available, but this can be discussed later.
