I keep getting the following in my daily log emails from Freenas. I have 3 Hitachi XL2000 2tb USB drives hooked up in a raidz1 volume. The volume shows healthy and I've never had trouble accessing it. I thought my USB hub might have been causing the problems so I removed it and hooked up all the drives to the motherboard USB ports and I still keep getting the errors. I would appreciate it if anyone could give me some insight. The errors are as follows...
