Started seeing hard read errors on the cloud node in the ZFS mirror set recently. Turns out my oldest hard drive in that cloud node (excluding the Samsung 830 SSD, I don't think that will ever get old) at a venerable 1.92 years of being switched on has started to see Raw Read Errors. Poo, that means I'll need to replace it, it's so tedious :(

Still, I once again have much gratititude to FreeNAS for regularly testing drives every two weeks for this stuff and emailing me to tell me of the problem, and of course it's on a mirror pair, so no data loss is expected.
