Serviceguard NFS for LINUX Introduction
Overview of the NFS File Lock Migration Feature
Chapter 1 9
•After sm-notify/rpc.statd sends the crash recovery notification
messages, the SM entries in the package holding directory are
removed, and the nfs.flm script is started on the adoptive node. The
script once again copies each file in sm directory (/var/lib/nfs/sm
on SLES and /var/lib/nfs/statd/sm on RedHat) of the NFS
server into the holding directory periodically. The entries that now
appear in the sm directory on the adoptive node following the
package migration represent either a client that has reclaimed its
locks or a client that has established new locks after failover.
