I've owned my FreeNAS system for about 4 years now. I have my system setup up with a RAIDZ2 configuration with 1 vdev spanning 8x5Tb WD Red Hard-drives. I have one WD 5tb drive marked as a hot spare.
Within the last 3 months, I've had or am having 3 drive failure. At first it was the Hot spare (which theoretically never gets used), then it was one of the drives in the main pool. I replaced those two drives but now I'm getting another drive failing test 1 of the smartctl short test. Needless to say I'm not happy. At this rate I'll have all the drives fail within a year.
Is this common?
