From mboxrd@z Thu Jan 1 00:00:00 1970 From: Wendy Cheng Date: Mon, 14 Aug 2006 02:00:21 -0400 Subject: [Cluster-devel] [PATCH 2/5] NLM failover - per fs grace period Message-ID: <1155535221.3416.26.camel@localhost.localdomain> List-Id: To: cluster-devel.redhat.com MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit This change enables per NFS-export entry lockd grace period. The implementation is based on a global single linked list nlm_servs that contains entries of fsid info. It is expected this would not be a frequent event. The nlm_servs list should be 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 /proc/fs/nfsd/nlm_set_igrace file as: shell> echo 1234 > /proc/fs/nfsd/nlm_set_igrace Signed-off-by: S.
