Hi everybody
I've got the alert for the first time a few days ago that my pool is degraded due to 15 read errors on one of the drives (see picture below). I've completed a long S.M.A.R.T. test and did a scrub since which did not resolve it. The hardware of my PC is in my signature.
Output for smartctl -a /dev/sdf
Output for zpool status -v
While the the S.M.A.R.T. tests don't show anything remarkable (as far as i can tell) and the pool status sais "no known data errors" I'm at a loss to what the problem is. What do I need to do to clear the degraded status?
If of importance: a few days prior to the error showing up i shut down the system via webinterface, opened the case up and cleaned it and the airfilters with canned air.
