export_mvfs

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

APPLICABILITY

ProductCommand type
ClearCasecommand

Platform
UNIX

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 products outside the ClearCase Product Family 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.
