Re: [Linux-cluster] NFS mount problem..



I did kick up the logging on the node and it did give me that same info.  The way figured it out was by modifying the netfs.sh script to log what it was looking for and what it was actually finding.  It was looking for /mnt/mysql/ not /mnt/mysql.  This is according to the awk statement at the end of the isMounted function in that script.  Once I found out what it was looking for, I was able to get it to work.  This sounds like a bug to me more than anything.

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.

           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 ?

              Spencer,

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