[Linux-HA] NFS: Permission denied

[Michael Scholl]

Hi,

after a failover my NFS clients report "Permission denied"  while trying 
to acces NFS mounts.
umount the NFS mount works but I get
rpc.mountd: refused unmount request from 10.0.3.17 for /data/base/usr 
(/): no export entry
on the backup server. Mounting it again works but this is not what i 
expect. Anybody knows how to get it fixed?

I'm using Linux-2.6.12.3 on both, the clients and the servers.
