Are one of the disks beginning to fail?
These messages appeared in the kern log file the other day:

The disk announces itself as:

Elsewhere on the Net I’ve been reading about faulty SATA cables and insufficient power. I doubt the 850 W power supply is to blame, unless there’s a faulty wiring. Maybe it’s a faulty SATA cable.
ZFS still hasn’t detected anything wrong, neither when running the last scrub or in the meantime.
