mountall

Name
     mountall, umountall - mount, unmount multiple file systems

Synopsis
     mountall [-F FSType] [-l | -r] [file_system_table]


     umountall [-k] [-s] [-F FSType] [-l | -r] [-n]  [-Z]


     umountall [-k] [-s] [-h host] [-n] [-Z]

Description
     mountall is used to mount file systems specified in  a  file
     system  table.  The  file  system table must be in vfstab(4)
     format. If no file_system_table is specified, /etc/vfstab is
     used. If - is specified as file_system_table, mountall reads
     the file system table  from  the  standard  input.  mountall
     mounts  only those file systems with the mount at boot field
     set to yes in the file_system_table.


     For each file system in the file system table, the following
     logic     is     executed:     if     there     exists     a
     file/usr/lib/fs/FSType/fsckall, where FSType is the type  of
     the  file  system,  save  that  file  system in a list to be
     passed  later,  and  all  at  once,  as  arguments  to   the
     /usr/lib/fs/FSType/fsckall            script.            The
     /usr/lib/fs/FSType/fsckall script checks  all  of  the  file
     systems  in  its argument list to determine whether they can
     be safely mounted. If no  /usr/lib/fs/FSType/fsckall  script
     exists for the FSType of the file system, the file system is
     individually checked using fsck(1M). If the file system does
     not  appear  mountable,  it  is  fixed using fsck before the
     mount is attempted. File systems  with  a  -  entry  in  the
     fsckdev field are mounted without first being checked.


     umountall causes all mounted file  systems  in  the  current
     zone except root, /usr, /var, /var/adm, /var/run, /proc, and
     /dev/fd to be unmounted. If the FSType is  specified,  moun-
     tall  and umountall limit their actions to the FSType speci-
     fied. There is no guarantee  that  umountall  unmounts  busy
     file systems, even if the -k option is specified.

Options
     The following options are supported:

     -F
                Specify the FSType  of  the  file  system  to  be
                mounted or unmounted.

     -h host
                Unmount all file systems  listed  in  /etc/mnttab
                that are remote-mounted from host.


     -k
                Use the fuser -k  mount-point  command.  See  the
                fuser(1M)  for  details.  The -k option sends the
                SIGKILL signal to each process using the file. As
                this  option  spawns  kills for each process, the
                kill messages  might  not  show  up  immediately.
                There  is  no  guarantee  that umountall unmounts
                busy file systems,  even  if  the  -k  option  is
                specified.


     -l
                Limit the action to local file systems.


     -n
                List the actions that would be performed for  the
                specified  options,  but  do not actually execute
                these actions. Repeating the command without  the
                -n  option  executes the listed actions, assuming
                that the /etc/mnttab file has not changed in  the
                interval prior to repeating the command.


     -r
                Limit the action to remote file system types.


     -s
                Do not perform the umount operation in parallel.


     -Z
                Apply the action(s)  only  to  the  file  systems
                mounted  in  non-global zones. By default, umoun-
                tall unmounts only file systems  mounted  in  the
                current  zone.  Option -Z is ignored if used in a
                non-global zone.

Files
     /etc/mnttab
         Mounted file system table


     /etc/vfstab
         Table of file system defaults


     /usr/lib/fs/FSType/fsckall
         Script called by mountall to  perform  the  file  system
         check of all file systems of type FSType

Diagnostics
     No messages are printed if the file  systems  are  mountable
     and clean.


     Error and warning messages come from fsck(1M) and mount(1M).

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