today ,i changed my DB binary log dir,when i restart percoan5.5.21,i find the DB still read binary log in old dir instead of new dir

my solution is :

create a Symbol link,then start mysql,and remove the link.

Neither of these things is a bug. Item 1 is misconfiguration and item 2 is you running out of disk space.
