I have multiple zpools with USB drives. Under normal conditions everything is idle as it should. But when I zfs send | zfs receive from one pool to another the unrelated pools have one read/s on each disk. Once the zfs send/receive is stopped the reads to the unrelated pools also stop. Size of the unexpected reads varying below 8k, usually 7.xk, but I've also seen 4.xk. The read sizes on all disks of all pools are identic. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
