I was checking through disk log information from the WebGUI this morning when I came across some errors and warnings listed on disk7:

Diagnostics also attached.

 

Is this anything to worry about?

Additional info:

 

The case hasn't been opened since Feb/Mar time frame, so there shouldn't have been any SATA cables being dislodged.

Server's been up for 56 days now, and last reboot was for the 6.3.5 update.

Doesn't look serious, could still be cable related, I'd wait a few days to see if it repeats or it was a one time thing.

Thanks, Jonnie. I'll keep an eye on it.
