One of my two raidz (master) ALWAYS has CKSUM errors on the same two disks but scrubs show the file system is fine. These disks are HGST and about 1-year old running 24/7/365, but the errors on the same two disks have been happening since new. Should I replace them or just keep an eye of the accumulating CKSUM errors.
