    Just updated to latest version r151012

    Still same... I checked for vdev settings, is there another place I can check?

    root at zfs10:/root# echo "::zfs_params" | mdb -k | grep vdev
    zfs_vdev_max_active = 0x3e8
    zfs_vdev_sync_read_min_active = 0xa
    zfs_vdev_sync_read_max_active = 0xa
    zfs_vdev_sync_write_min_active = 0xa
    zfs_vdev_sync_write_max_active = 0xa
    zfs_vdev_async_read_min_active = 0x1
    zfs_vdev_async_read_max_active = 0x3
    zfs_vdev_async_write_min_active = 0x1
    zfs_vdev_async_write_max_active = 0xa
    zfs_vdev_scrub_min_active = 0x1
    zfs_vdev_scrub_max_active = 0x2
    zfs_vdev_async_write_active_min_dirty_percent = 0x1e
    zfs_vdev_async_write_active_max_dirty_percent = 0x3c
    mdb: variable reference_tracking_enable not found: unknown symbol name
    mdb: variable reference_history not found: unknown symbol name
    zfs_vdev_cache_max = 0x4000
    zfs_vdev_cache_size = 0x0
    zfs_vdev_cache_bshift = 0x10
    vdev_mirror_shift = 0x15
    zfs_vdev_aggregation_limit = 0x20000

    It should be available in r151010!  That's why I'm surprised.
