19 mountall is used to mount file systems specified in a file system ta‐
20 ble. The file system table must be in vfstab(4) format. If no file_sys‐
21 tem_table is specified, /etc/vfstab is used. If − is specified as
22 file_system_table, mountall reads the file system table from the stan‐
23 dard input. mountall mounts only those file systems with the mount at
24 boot field set to yes in the file_system_table.
25 For each file system in the file system table, the following logic is
28 executed: if there exists a file/usr/lib/fs/FSType/fsckall, where
29 FSType is the type of the file system, save that file system in a list
30 to be passed later, and all at once, as arguments to the
31 /usr/lib/fs/FSType/fsckall script. The /usr/lib/fs/FSType/fsckall
32 script checks all of the file systems in its argument list to determine
33 whether they can be safely mounted. If no /usr/lib/fs/FSType/fsckall
34 script exists for the FSType of the file system, the file system is
35 individually checked using fsck(1M). If the file system does not appear
36 mountable, it is fixed using fsck before the mount is attempted. File
37 systems with a − entry in the fsckdev field are mounted without first
38 being checked.
39 umountall causes all mounted file systems in the current zone except
42 root, /usr, /var, /var/adm, /var/run, /proc, and /dev/fd to be
43 unmounted. If the FSType is specified, mountall and umountall limit
44 their actions to the FSType specified. There is no guarantee that
45 umountall unmounts busy file systems, even if the -k option is speci‐
46 fied.
47
49 The following options are supported:
50 -F Specify the FSType of the file system to be mounted or
52 unmounted.
53 -h host Unmount all file systems listed in /etc/mnttab that are
56 remote-mounted from host.
57 -k Use the fuser -k mount-point command. See the fuser(1M) for
60 details. The -k option sends the SIGKILL signal to each
61 process using the file. As this option spawns kills for each
62 process, the kill messages might not show up immediately.
63 There is no guarantee that umountall unmounts busy file sys‐
64 tems, even if the -k option is specified.
65 -l Limit the action to local file systems.
68 -n List the actions that would be performed for the specified
71 options, but do not actually execute these actions. Repeat‐
72 ing the command without the -n option executes the listed
73 actions, assuming that the /etc/mnttab file has not changed
74 in the interval prior to repeating the command.
75 -r Limit the action to remote file system types.
78 -s Do not perform the umount operation in parallel.
81 -Z Apply the action(s) only to the file systems mounted in
84 non-global zones. By default, umountall unmounts only file
85 systems mounted in the current zone. Option -Z is ignored if
86 used in a non-global zone.

126 No messages are printed if the file systems are mountable and clean.
127 Error and warning messages come from fsck(1M) and mount(1M).

132 At this time, NFS is the only remote file system supported by the -l,
133 -r, and -h options.
