[Mekathotti, Sudhakar]

> Hello,
> 
> Recently setup a 4 node replicated glusterfs. Trying to run mysql on
> it and coming across the following error.
> 
> mysqld[28115]: InnoDB: Check that you do not already have another
> mysqld process
> mysqld[28115]: InnoDB: using the same InnoDB data or log files.
> mysqld[28115]: InnoDB: Unable to lock ./ibdata1, error: 11
> 
> Exported filesystem is mounted on all 4 nodes.
> I've checked to make sure that there's no other instance running. I
> googled and found several others having issues with InnoDB on
> glusterfs, but couldn't find any solution. I would appreciate if you
> could take a quick look at the config files and see if there's
> anything I'm doing wrong. Configured using examples from gluster.org.

> Apologies for long config listing...pastebin is blocked at work!!
