6 fixmount - fix remote mount entries

12 fixmount is a variant of showmount(8) that can delete bogus mount
13 entries in remote mountd(8) daemons. The actions specified by the
14 options are performed for each host in turn.
15
17 -a -d -e
18 These options work as in showmount(8) except that only entries
19 pertaining to the local host are printed.
20 -r Removes those remote mount entries on host that do not corre‐
22 spond to current mounts, i.e., which are left-over from a crash
23 or are the result of improper mount protocol. The actuality of
24 mounts is verified using the entries in /etc/mtab.
25 -v Verify remote mounts. Similar to -r except that only a notifi‐
27 cation message is printed for each bogus entry found. The
28 remote mount table is not changed.
29 -A Issues a command to the remote mountd declaring that ALL of its
31 filesystems have been unmounted. This should be used with cau‐
32 tion, as it removes all remote mount entries pertaining to the
33 local system, whether or not any filesystems are still mounted
34 locally.
35 -q Be quiet. Suppresses error messages due to timeouts and "Pro‐
37 gram not registered", i.e., due to remote hosts not supporting
38 RPC or not running mountd.
39 -h name
41 Pretend the local hostname is name. This is useful after the
42 local hostname has been changed and rmtab entries using the old
43 name remain on a remote machine. Unfortunately, most mountd's
44 won't be able to successfully handle removal of such entries, so
45 this option is useful in combination with -v only.
46 This option also saves time as comparisons of remotely recorded
47 and local hostnames by address are avoided.
48
50 /etc/mtab List of current mounts.
51 /etc/rmtab Backup file for remote mount entries on NFS server.
53
55 showmount(8), mtab(5), rmtab(5), mountd(8C).
56 ``am-utils'' info(1) entry.

67 No attempt is made to verify the information in /etc/mtab itself.
68 Since swap file mounts are not recorded in /etc/mtab, a heuristic spe‐
70 cific to SunOS is used to determine whether such a mount is actual
71 (replacing the string "swap" with "root" and verifying the resulting
72 path).
73 Symbolic links on the server will cause the path in the remote entry to
75 differ from the one in /etc/mtab. To catch those cases, a filesystem
76 is also deemed mounted if its local mount point is identical to the
77 remote entry. I.e., on a SunOS diskless client,
78 server:/export/share/sunos.4.1.1 is actually /usr/share. Since the
79 local mount point is /usr/share as well this will be handled correctly.
80 There is no way to clear a stale entry in a remote mountd after the
82 local hostname (or whatever reverse name resolution returns for it) has
83 been changed. To take care of these cases, the remote /etc/rmtab file
84 has to be edited and mountd restarted.
85 The RPC timeouts for mountd calls can only be changed by recompiling.
87 The defaults are 2 seconds for client handle creation and 5 seconds for
88 RPC calls.
