Subject: [Cluster-devel] [PATCH 2/4 Revised] NLM failover - nlm_set_igrace
Date: Thu, 14 Sep 2006 00:48:26 -0400 [thread overview]
Message-ID: <4508DF1A.4090907@redhat.com> (raw)
This change enables per NFS-export entry lockd grace period. The
implementation is based on a double linked list fo_fsid_list that
contains entries of fsid info. It is expected this would not be a
frequent event. The fo_fsid_list is short and the entries expire within
a maximum of 50 seconds. The grace period setting follows the existing
NLM grace period handling logic and is triggered via echoing the NFS
export filesystem id into nfsd procfs entry as:
shell> echo 1234 > /proc/fs/nfsd/nlm_set_igrace
