Yes Scott! Only thing that confused and still confusing me is the following note on mysql site -
"*Note* It is not a good idea to configure InnoDB to use datafiles or logfiles on NFS volumes. Otherwise, the files might be locked by other processes and become unavailable for use by MySQL. " http://dev.mysql.com/doc/refman/5.0/en/innodb-configuration.html Why other processes will keep files locked if its on NFS volumes? and which are the processes they are referring?
