constantly I find data corruption on ZFS volums, ever from rrdtool, this 
corrupt data happens on SATA disks, never seem on SCSI

scrub is not able to repair, when comes to touch this files machines reboots, 
deleting and restorin also is not possíble, seems I need to delete the files, 
umount, scrub and mount again to clear it

# zpool status -v os
  pool: os
 state: ONLINE
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.
 scrub: none requested
