I have OMV running on an Intel system with M.2 NVME drive, 4x4TB data drives with UnionFS and SnapRAID. I have Emby running on a seperate Ubuntu system feeding several Kodi devices from media on OMV.
Since changing from RAID 5 to the above setup a week ago a lot of the .nfo files now have zero file size - everything works as before as far I can make out.
On running the SnapRAID helper script
I get a few messages about this. Is this anything to worry about?
