34 .Nd notify NFS servers about unmounted NFS file systems
40 .Op Fl p Ar remotepath
45 utility is proposed in the
47 RPC specification; see
49 .%T "NFS Version 3 Protocol Specification"
50 .%O "RFC 1813, Appendix I"
52 It uses remote procedure calls to remove mount entries from
54 on the remote NFS server.
55 It is called automatically
56 without any parameters during startup and shutdown of
60 does not display old and expired entries.
64 is only needed on client side, where
66 adds a mount entry with the current date to
67 .Pa /var/db/mounttab ,
70 removes the entry again.
74 cares about all remaining entries in this table which result from crashes
75 or unproper shutdowns.
77 The options are as follows:
78 .Bl -tag -width indentxxx
80 All entries which are not actually mounted or older than
82 (seconds) are removed from
83 .Pa /var/db/mounttab .
85 for DNS changes or long out of service periods.
87 is 86400 seconds (one day).
89 Only remove the specific hostname.
90 Send a UMNTALL RPC to the NFS server.
92 Keep entries for existing NFS file systems.
93 Compare the NFS file systems from
94 the mounttab against the kernel mountlist and do not send the RPC to
95 existing mount entries.
96 Useful during startup of the system.
98 possible that there are already mounted NFS file systems, so calling
99 RPC UMOUNT is not a good idea.
100 This is the case if the user has rebooted
101 to 'single user mode' and starts up the system again.
103 Only remove the specific mount-path.
104 Send a UMOUNT RPC to the NFS server.
105 This option implies the
109 Verbose, additional information is printed for each processed mounttab
113 .Bl -tag -width /var/db/mounttab -compact
114 .It Pa /var/db/mounttab
115 mounted nfs-file systems
