Unless I'm misunderstanding this output... It looks like all disks are doing approx the same data throughput. It looks like sd1 & sd2 are doing half the IOPS. So sd1 & sd2 must be doing larger chunks. How are these drives configured? One vdev of raidz2? No cache/log devices, etc... It would be easy to explain, if you're striping mirrors. Difficult (at least for me) to explain if you're using raidzN. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
