Yikes! RAID0 has no redundancy! I hope you have a backup!

Run zpool status -v and provide the output.

The file listed appears to have corruption that it cannot correct. If you can delete and replace it, that is likely the best course of action. The good thing is it sounds like it's only one file and everything else is okay.

So, if you can replace the following file, you should be okay I think.

/mnt/khan1/media1/Movies/Sicario.2015.2160p.BluRay.x265.10bit.SDR.DTS-HD.MA.TrueHD.7.1.Atmos-SWTYBLZ/Sicario.2015.2160p.BluRay.x265.10bit.SDR.DTS-HD.MA.TrueHD.7.1.Atmos-SWTYBLZ.mkv
