Hello folks. Happy Halloween. If anyone gets bored I was wanting to get an opinion on a recent read error on my parity drive. I have had small issues in the past with a hdd controller sticking/freezing once ever few months or so. If i remember i think the marvel controller. But its never kicked a drive out of the array before and always resolved itself quickly with some kind of controller reset without manual intervention. Guess I'll run a preclear or something on it and go from there. Smart comes back fine but that doesn't really mean much i don't think.

This might be an example of where it looks like the controller resets for a couple of weeks ago but not sure. It doesn't seem quite the same as the errors that kicked the parity drive out of the array:

Probably should have posted in support channel. Sorry

Looks more like a power/connection issue, I would replace both cables first.

That was in the back of my mind. Not seeing anything wrong with drive. Thanks for taking a look, much appreciated.
