[dm-devel] Multipath device error

[Cu.auto.fw@gmail.com]

    i found simillar error like this:
 >
 > refer tohttps://bugzilla.redhat.com/show_bug.cgi?id=516170.
 >
 > "When an attempt is made to read a bad sector via a multipath  
device, the
 > multipath driver fails the path it hit the medium error through,  
and tries
 > again through the next path. Meanwhile the multipathd daemon re- 
enables the
 > path. As a result the I/O hangs forever (even if you unset the
 > queue_if_no_path
 > feature and set no_path_retry to something sensible, because the  
paths get
 > re-enabled we never get to the point where there are no live paths).
 > "
 >
 > is th above bug closed?  how can i resolve it?  i would be very  
thankful if
 > you can give me some information.

 > Best regards,
