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