I can hit either ZFS or the UFS drive hard (running bonnie++) and things are fine. But as soon as I start hitting both of them, I start getting errors: Sep 6 03:16:31 noel kernel: (da0:umass-sim0:0:0:0): AutoSense failed Sep 6 03:16:31 noel root: ZFS: vdev I/O failure, zpool=zsb path=/dev/da0 offset=1145095418880 size=1024 error=5 (I'll get some number of the second error, usually between 5 and 20 per incident). The frequency of these errors is dependent on workload. I've been rsyncing some data at a rate of ~500kB/s (rsync --bwlimit=500) and that's generating roughly 3 events per hour: Sep 6 00:36:00 noel kernel: (da1:umass-sim1:1:0:0): AutoSense failed Sep 6 01:37:11 noel kernel: (da1:umass-sim1:1:0:0): AutoSense failed Sep 6 01:38:25 noel kernel: (da1:umass-sim1:1:0:0): AutoSense failed Sep 6 01:40:02 noel kernel: (da1:umass-sim1:1:0:0): AutoSense failed Sep 6 01:41:03 noel kernel: (da1:umass-sim1:1:0:0): AutoSense failed Sep 6 01:41:34 noel kernel: (da1:umass-sim1:1:0:0): AutoSense failed Sep 6 02:18:27 noel kernel: (da0:umass-sim0:0:0:0): AutoSense failed Sep 6 02:37:36 noel kernel: (da1:umass-sim1:1:0:0): AutoSense failed Sep 6 02:42:30 noel kernel: (da1:umass-sim1:1:0:0): AutoSense failed Sep 6 03:13:30 noel kernel: (da0:umass-sim0:0:0:0): AutoSense failed Sep 6 03:15:38 noel kernel: (da1:umass-sim1:1:0:0): AutoSense failed Sep 6 03:16:31 noel kernel: (da0:umass-sim0:0:0:0): AutoSense failed The errors are always on the ZFS drives (da0, da1); I haven't seen any on the UFS drive. decibel@noel.2[22:32]~:15>sudo usbconfig ugen0.1: at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen1.1: at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen1.2: at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen1.3: at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen1.4: at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen0.2: at usbus0, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON >How-To-Repeat: Hopefully someone else can repeat this with a similar setup. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
