Question about Heartbeat (II)

[Matias Villarreal]

Hey, I need some help on this.

I have a 2-node cluster. It has SAP. Haresources has: IP - LVM(VG) - FILESYSTEMS - nfsserver - MOUNT FOR NFS (3 of the previously mounted on FILESYSTEMS parameter) - SAP.

The 2 nodes has the same hareresources. I start heartbeat on node1. It sets up the IP cluster, actives the VG, mounts the FS, starts nfsserver, mounts the NFS (they are cluster FSs mounted through the cluster IP) and finally it starts SAP. 

Then i go to the node2 and mount the same NFS as heartbeat mounted on node1. The NFS are mounted with the cluster IP. Then we start heartbeat so that if node1 crash out, it makes the faillover. After this we start the SAP instance on node2, that access the NFS mounted previously for us (on node2). When i test the faillover, it goes well, but when i go to node2 and issue the df command, I see the NFS went stale. I have them on both /etc/exports with the same fsid.

See...

The /nfs mounted by heartbeat on node1 has a folder called nfs with the files that contains the /var/lib/nfs directory. I mved the /var/lib/nfs directory and created a link, like this:

EMNEOL902:/etc/ha.d # ls -l /var/lib/nfs
lrwxrwxrwx 1 root root 8 Apr 28 21:57 /var/lib/nfs -> /nfs/nfs


Does somebody think anything about this?

Thanks in advance.
