Red Hat ENTERPRISE LINUX 5 - DEPLOYMENT Deployment Manual page 279

• Allow connections from port 1024 and higher — Services started on port numbers less than
1024 must be started as root. Select this option to allow the NFS service to be started by a user
other than root. This option corresponds to insecure.
• Allow insecure file locking — Do not require a lock request. This option corresponds to
insecure_locks.
• Disable subtree checking — If a subdirectory of a file system is exported, but the entire file system
is not exported, the server checks to see if the requested file is in the subdirectory exported. This
check is called subtree checking. Select this option to disable subtree checking. If the entire file
system is exported, selecting to disable subtree checking can increase the transfer rate. This option
corresponds to no_subtree_check.
• Sync write operations on request — Enabled by default, this option does not allow the server
to reply to requests before the changes made by the request are written to the disk. This option
corresponds to sync. If this is not selected, the async option is used.
• Force sync of write operations immediately — Do not delay writing to disk. This option
corresponds to no_wdelay.
• Hide filesystems beneath turns the nohide option on or off. When the nohide option is off,
nested directories are revealed. The clients can therefore navigate through a filesystem from the
parent without noticing any changes.
• Export only if mounted sets the mountpoint option which allows a directory to be exported only if
it has been mounted.
• Optional Mount Point specifies the path to an optional mount point. Click on the Browse to
navigate to the preferred mount point or type the path if known.
• Set explicit Filesystem ID: sets the fsid=X option. This is mainly used in a clustered setup. Using
a consistent filesystem ID in all clusters avoids having stale NFS filehandles.
