Competely lost here ...

Found what command replaced the "zfs_vdev_max_pending" , and it make
no difference !

First, I added this command to /etc/system :

set zfs:zfs_vdev_max_active = 1

make no diference, then added all this parameters :

set zfs:zfs_vdev_async_read_max_active  = 3
set zfs:zfs_vdev_async_read_min_active  = 1
set zfs:zfs_vdev_async_write_max_active  = 11
set zfs:zfs_vdev_async_write_min_active  = 1
set zfs:zfs_vdev_max_active = 1
set zfs:zfs_vdev_scrub_max_active = 2
set zfs:zfs_vdev_scrub_min_active = 1
set zfs:zfs_vdev_sync_read_max_active  = 10
set zfs:zfs_vdev_sync_read_min_active  = 10
set zfs:zfs_vdev_sync_write_max_active = 1
set zfs:zfs_vdev_sync_write_min_active = 1
set zfs:zfs_vdev_async_write_active_max_dirty_percent = 60
set zfs:zfs_vdev_async_write_active_min_dirty_percent = 30

no diference either ...

Yes. I rebooted the machine for the first and the second try .

Someone has any clue ?
