export_mvfs

Exports and unexports VOBs to NFS clients (non-ClearCase access)

APPLICABILITY

SYNOPSIS

• Digital UNIX platforms:

ccase-home-dir/etc/export_mvfs -a [ -i ] [ -u [ -r ] ] [ -v ] [ -I exportid ] [ -o options ] [ pname ]

or

ccase-home-dir/etc/export_mvfs [ -a ] [ -i ] [ -u [ -r ] ] [ -v ] [ -I exportid ] [ -o options ] pname

• All other platforms:

ccase-home-dir/etc/export_mvfs [ -a ] [ -i ] [ -u [ -r ] ] [ -v ] [ -I exportid ] [ -o options ] [ pname ]

DESCRIPTION

The export_mvfs command enables access by non-ClearCase-family-products by making a local VOB available for mounting over the network by hosts on which ClearCase is not installed. This command is the ClearCase counterpart of the exportfs(1M) (HPUX-10, HPUX-11, IRIX, AIX-4, UnixWare) or share(1M) (Solaris 2, MP-RAS, Reliant UNIX) command for file systems of type MVFS.

RESTRICTIONS

Identities: You must be root.

Locks: No locks apply.

Mastership: (Replicated VOBs) No mastership restrictions.

OPTIONS AND ARGUMENTS

With no options or arguments, export_mvfs lists the VOBs currently exported by the host (except on Digital UNIX).

-a

(All) Exports all pathnames listed in /etc/exports.mvfs; with -u, unexports all currently exported VOBs.

-i

Ignores the options in /etc/exports.mvfs. By default, export_mvfs consults /etc/exports.mvfs for the options associated with each pathname to be exported.

-u [ -r ]

Unexports the specified pathnames. With -a, unexports all currently exported VOBs. With -r, removes view/export-ID mapping from the MVFS but leaves the view active.

-v

(Verbose) Displays each pathname as it is exported or unexported.

-I exportid

Specifies an export-ID for temporary NFS export of a view. Start with export-ID 4095 and work down. (View export IDs that are assigned automatically start at 1 and work up.)

NOTE: Do not use this option for views that already have export-IDs assigned in the ClearCase registry. Use lsview -long view-tag to determine whether a view has an assigned export-ID.

-o options

A comma-separated list of optional characteristics for the pathnames being exported. See the exports_ccase reference page for the supported options.

pname

A view-extended pathname to the VOB-tag (mount point) of the VOB to be exported.
