Description Sachin Prabhu 2009-06-12 06:40:50 EDT
A notify request sent by a client is being ignored by the server resulting in unclaimed file locks on the server. The client in this case is a RHEL and the NFS server a Netapp server. The problem appears to be caused by a mismatch in the hostnames used by lockd and by statd.

The hostname on the server is set to a short name(ex: test). This short name is used by lockd when setting the hostname from which the locks were requested. 

The /etc/hosts is setup in such a way that a FQDN(ex: test.example.com) is returned by gethostbyaddr(). This is used by statd on the client when notifying servers that the machine has rebooted.

This is causing a problem on their Netapp servers which expects the same hostname used to set the locks and in by statd. 

This is a request to have the statd and the lockd to use the same source for setting hostnames.
