I found my problem.  It was the trailing slash on /mnt/mysql

Glad that you found the problem. Just curious that your log didn't show any clear clue. Below is my log in a similar situation. It says pretty clear that there is something wrong in my mount parameters.

Btw, I use RHEL 5.2, just plain 5.2 from the DVD without any RHN update.

             The NFS share is only there to share the database

            it goes to check the status of the NFS mount.

            Jan  9 13:50:40 shadowhawk clurgmgrd[4212]: <notice> status

            That is the error coming out of my log file.  It mounts the
            NFS share just fine...and leaves it mounted as well.  When
            it checks the status it then errors out.


        What is your cluster.conf ?

            run fine
                   until add in an NFS mount.  The NFS mount is where
            all of the

            mount
                   properly on the cluster machines, but the log files
            keep telling
                   it errors out.  Once it errors out the service then
            stops.  I
                   have tried restarting the service, but that has it
            remounting
                   the share over the top of the old one.  It never
            unmounts the
                   NFS share upon failure.  I can manually mount it and
            it works
                   fine...I can read-write to it just fine...I have added in
                   options and taken them away.  All of this results in
            the same
                   end.  Any ideas?


               Spencer,

               How do you share the NFS ? Do you use GSF ?  What are the
            error
               messages ? Is the storage-device iscsi ?
