NFS:

• Filesystem fuser fix
• NFS-Faq

STATD

• SIGUSR1 causes rpc.statd to re-read the notify list from disk and send notifications to clients. This can be used in High Availability NFS (HA-NFS) environments to notify clients to reacquire file locks upon takeover of an NFS export from another server.

FILES /var/lib/nfs/statd/sm/state /var/lib/nfs/statd/sm/* /var/lib/nfs/statd/sm.bak/*

• A better functional description

Clients:

• Options I should always use: lock, nfsver=3(4), nosuid, sync

Servers

• Investigate the wdelay and sync combination (or is wdelay only async)
