In the future, you'll find it easier to go to Tools -> Diagnostics and have unRAID generate & download a nice .ZIP package of all the necessary log & config files for you. Then you can just post the .ZIP here. In almost all cases, it contains all the info the experts here (I'm definitely not one of them) will need to help assess & fix the situation.

Disk9 is failing, if disk14 is disable and since you only have single parity you have a problem:

SMART overall-health self-assessment test result: FAILED!
Drive failure expected in less than 24 hours. SAVE ALL DATA.

 

P.S: Always post the diagnostics.zip in a single attachment.

If disk14 was replaced and you still have old one you may try to recover data from there, if not, you can try to copy data form both disk9 and the emulated disk14 to other disks or better yet, another computer, start with the most important data, but with one disk failed and another one failing there's a big chance you're going to lose data from both.
