Hi All

 

I am moving a lot of data on my Unraid server, and this morning I got this in the log file.

(I have an array with 2 x Parity drives, was hoping these would correct errors)

The disk have no errors in the SMART logs and the check is fine?

 

Can I ignore this? no errors transferring data so would these be corrupt?

Any recommendation to apps/tools for checksum or other solution to mitigate this when it happens?

 

As always thanks for helping out spending your time answerings our many questions

Sure thing

It was a media error, i.e., bad or failing sector, though SMART still looks good, you should run an extended SMART test, but since SMART shows more than one read error on very different sectors I would replace it.

 

Since the disk didn't get disabled Unraid could successfully re-write those sectors, so data is good for now, as long as it can be read back from that disk, or on a disk emulated by parity.

@johnnie.black Thanks! copying all data away from the drive now!

Why not just replace and rebuild to a new disk instead?

 

Or if you intend to remove it instead of replacing it you will have to New Config and rebuild parity.
