34 .Nd notify NFS servers about unmounted NFS file systems
40 .Op Fl p Ar remotepath
46 utility is proposed in the
48 RPC specification; see
50 .%T "NFS Version 3 Protocol Specification"
51 .%O "RFC 1813, Appendix I"
53 It uses remote procedure calls to remove mount entries from
55 on the remote NFS server.
56 It is called automatically
57 without any parameters during startup and shutdown of
61 does not display old and expired entries.
65 is only needed on client side, where
67 adds a mount entry with the current date to
68 .Pa /var/db/mounttab ,
71 removes the entry again.
75 cares about all remaining entries in this table which result from crashes
76 or unproper shutdowns.
78 The options are as follows:
79 .Bl -tag -width indentxxx
81 All entries which are not actually mounted or older than
83 (seconds) are removed from
84 .Pa /var/db/mounttab .
86 for DNS changes or long out of service periods.
88 is 86400 seconds (one day).
90 Only remove the specific hostname.
91 Send a UMNTALL RPC to the NFS server.
93 Keep entries for existing NFS file systems.
94 Compare the NFS file systems from
95 the mounttab against the kernel mountlist and do not send the RPC to
96 existing mount entries.
97 Useful during startup of the system.
99 possible that there are already mounted NFS file systems, so calling
100 RPC UMOUNT isn't a good idea.
101 This is the case if the user has rebooted
102 to 'single user mode' and starts up the system again.
104 Only remove the specific mount-path.
105 Send a UMOUNT RPC to the NFS server.
106 This option implies the
110 Verbose, additional information is printed for each processed mounttab
113 Fast mode. The resolver timeout is reduced to 4 seconds and the
114 pmap_getport() timeout is reduced from 60 seconds to 3. This option
117 is used in the boot sequence to facilitate booting.
