>Description:
Attempts to start slave replication fail when MySQL attempts to write
the bin-log location to the master.info file.
Attempts to manually change master also fail when writing to
master.info file.
master.info file is created, but has zero length (no info written)
>How-To-Repeat:
With valid master.info file:
issue slave start command.
MySQL replies:
Could not initialize master info structure, check permisions on master.info
Removed master.info file restart mysql and issue:
CHANGE MASTER TO MASTER_HOST = '...', MASTER_USER = '...', MASTER_PASSWORD =
'...', MASTER_PORT = 3306
MySQL replies:
Could not initialize master info
master.info file
-rw-rw---- 1 mysql mysql 0 Mar 18 14:53
/var/lib/mysql/master.info
Occured in both 4.0.11 and 4.0.12 at least. Load data from master still works
and transfers data correctly. I just cannot start the slave server.
