       vfstab - table of file system defaults

       The file /etc/vfstab describes defaults for each file system. The information is stored in
       a table with the following column headings:

	 device       device	   mount      FS      fsck    mount	 mount
	 to mount     to fsck	   point      type    pass    at boot	 options

       The fields in the table are space-separated and show the resource name (device to  mount),
       the  raw  device  to fsck (device to fsck), the default mount directory (mount point), the
       name of the file system type (FS type), the number used by fsck to decide whether to check
       the file system automatically (fsck pass), whether the file system should be mounted auto-
       matically by mountall (mount at boot), and the file system mount options (mount	options).
       (See  respective mount file system man page below in SEE ALSO for mount options.) A '-' is
       used to indicate no entry in a field. This may be used when a field does not apply to  the
       resource being mounted.

       The getvfsent(3C) family of routines is used to read and write to /etc/vfstab.

       /etc/vfstab can be used to specify swap areas. An entry so specified, (which can be a file
       or a device), will automatically be added as a swap area by the /sbin/swapadd script  when
       the  system  boots. To specify a swap area, the device-to-mount field contains the name of
       the swap file or device, the FS-type is "swap", mount-at-boot is "no" and all other fields
       have no entry.

       The  following  are  vfstab entries for various file system types supported in the Solaris
       operating environment.

       Example 1 NFS and UFS Mounts

       The following entry invokes NFS to automatically mount the  directory  /usr/local  of  the
       server example1 on the client's /usr/local directory with read-only permission:

	 example1:/usr/local - /usr/local nfs - yes ro

       The  following  example	assumes  a  small departmental mail setup, in which clients mount
       /var/mail from a server mailsvr. The following entry would  be  listed  in  each  client's

	 mailsvr:/var/mail - /var/mail nfs - yes intr,bg

       The following is an example for a UFS file system in which logging is enabled:

	 /dev/dsk/c2t10d0s0 /dev/rdsk/c2t10d0s0 /export/local ufs 3 yes logging

       See  mount_nfs(1M) for a description of NFS mount options and mount_ufs(1M) for a descrip-
       tion of UFS options.

       Example 2 pcfs Mounts

       The following example mounts a pcfs file system on a fixed hard disk on an x86 machine:

	 /dev/dsk/c1t2d0p0:c - /win98 pcfs - yes -

       The example below mounts a Jaz drive on a SPARC machine. Normally, the  volume  management
       software  handles  mounting  of	removable  media,  obviating a vfstab entry. Specifying a
       device that supports removable media in vfstab  with set the mount-at-boot field to no (as
       shown  below)  disables the  automatic handling of that device. Such an entry presumes you
       are not running volume management software.

	 /dev/dsk/c1t2d0s2:c - /jaz pcfs - no -

       For removable media on a SPARC machine, the convention for the slice portion of	the  disk
       identifier is to specify s2, which stands for the entire medium.

       For  pcfs  file systems on x86 machines, note that the disk identifier uses a p (p0) and a
       logical	drive  (c,  in	the  /win98  example  above)  for  a  pcfs  logical  drive.   See
       mount_pcfs(1M) for syntax for pcfs logical drives and for pcfs-specific mount options.

       Example 3 CacheFS Mount

       Below is an example for a CacheFS file system. Because of the length of this entry and the
       fact that vfstab entries cannot be continued to a second line, the vfstab fields are  pre-
       sented  here  in  a  vertical format. In re-creating such an entry in your own vfstab, you
       would enter values as you would for any vfstab entry, on a single line.

	 device to mount:  svr1:/export/abc
	 device to fsck:  /usr/abc
	 mount point:  /opt/cache
	 FS type:  cachefs
	 fsck pass:  7
	 mount at boot:  yes
	 mount options:

       See mount_cachefs(1M) for CacheFS-specific mount options.

       Example 4 Loopback File System Mount

       The following is an example of mounting a loopback (lofs) file system:

	 /export/test - /opt/test lofs - yes -

       See lofs(7FS) for an overview of the loopback file system.

       fsck(1M), mount(1M), mount_cachefs(1M),	mount_hsfs(1M),  mount_nfs(1M),  mount_tmpfs(1M),
       mount_ufs(1M), swap(1M), getvfsent(3C)
