My ZFS-on-Linux public facing server managed 289 days of trouble free uptime before today exhibiting massive i/o delay (see below) making it unusable without rebooting. That's the best it's ever achieved to date. Really shows how ZFS-on-Linux is becoming actually viable for reliable service provision, and as bug fixes land it's getting increasingly ever better.
