Oh yeah - this is also bizarre. I watched "zpool iostat" for a while. It was showing me : Operations (read and write) consistently 0 Bandwidth (read and write) consistently non-zero, but something small, like 1k-20k or so. Maybe that is normal to someone who uses zpool iostat more often than I do. But to me, zero operations resulting in non-zero bandwidth defies logic. _______________________________________________ zfs-discuss mailing list email@example.com http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
