Jan  9 13:50:40 shadowhawk clurgmgrd[4212]: <notice> status on netfs "mysql_data" returned 1 (generic error)

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 ?

       I am running a MySQL cluster using cluster services and I have

       MySQl databases live at.  I can get the NFS share to mount
       properly on the cluster machines, but the log files keep telling

       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 ?
