SSD disconnecting/erroring but fine after array reboot

[iTunes]

Hi guys, 

 

so recently my plex SSD which I've assigned as a pool device started getting random 'disconnects' (the drive is still connected but gives I/O errors.) resulting in my plex docker crashing. Whenever this happens all I have to do is reboot the array and everything will be up and running again... 

 

SMART reports no issues and to be honest I have no idea what to make out of the syslog messages... The drive in question is labeled sdq, it's the only kingston in the system...

 

Maybe this could be useful, the error plex reports in the docker log:

libc++abi: terminating with uncaught exception of type boost::filesystem::filesystem_error: boost::filesystem::create_directories: I/O error [system:5]: "/config/Library/Application Support/Plex Media Server/Cache", "/config/Library/Application Support/Plex Media Server/Cache"

Try replacing the cables, I would also recommend using the onboard SATA controller, for TRIM support.

Forgot to mention it's connected via backplane, I'll switch it around to straight to the onboard SATA. Wouldn't it affect the other SSD as well though (unless it's that specific slot that's giving problems)...

Just an update: hasn't occured since I connected it straight to the mobo SATA. Is there anything I can derive from the errors occuring when connected through the backplane?

Could be some compatibility issue with the other controller, also like mentioned onboard would be better for TRIM support.
