- All

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.
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.
