   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,
