Hi John,
Thank you for the reply.
This is kinda odd since there hasn't been any changes to the RAID 6 array and this warning first came up on 7/11/2019. I would think this warning would have been here since the array was created years ago. How does that work?
Also, RAID 6 arrays can handle 2 drive failures since it uses two parity stripes on each disk. So I shouldn't be getting this warning message since RAID is redundant array of independent disks. Kinda odd aswell.
Can I send you the logs via OneDrive link?
Thank you,
Leif

You will get this message if one (or two ) drives have failed or dropped out of the array. You haven't lost data, but you are being warned that the RAID protection has been degraded.
The green disk status doesn't necessarily mean the disks are healthy. I suggest you should send JohnCM_S a link to your log zip file so he can take a look at what's going on.
If you don't have a backup of your files, then I suggest that you make one. RAID isn't enough to keep your data safe (not even RAID-6).
