ibrix_exportfs
Maintains the list of NFS-exported file systems and specifies file system access for StoreAll clients.
Description
ibrix_exportfs makes local directories available for NFS clients to mount. The Fusion Manager
manages the table of exported file systems and distributes the information to local /etc/exports
files. All entries are automatically re-exported to NFS clients and, optionally, to the file serving
node standbys. A file system must be mounted before it can be exported. It must be unexported
before it can be unmounted.
The ibrix_exportfs command can also be used to control file-system access for StoreAll clients.
By default, all StoreAll clients can mount a file system after a mount point has been created. To
allow access for a file system (or a subdirectory of that file system) to a specific StoreAll client, use
the -c option to create an access entry containing that information. Then, when a StoreAll client
attempts to mount the file system, StoreAll software will allow access only to the clients in the access
entry.
Synopsis
Export a file system via NFS:
ibrix_exportfs -f FSNAME -h HOSTNAME -p
CLIENT1:PATHNAME1,CLIENT2:PATHNAME2,.. [-o "OPTIONS"] [-b]
File system FSNAME at mount point PATHNAME on file serving node HOSTNAME is exported to the
specified CLIENTS. The accessing CLIENT can be a single file serving node, file serving nodes
represented by a wildcard, or all hosts (:/PATHNAME), which is also known as world access.
World access omits the client specification but not the colon, for example, :/usr/src. By default,
the file system is exported to the NFS client’s standby. To exclude the standby, include the -b
option. The command uses the default Linux exportfs options unless specific options are provided.
NOTE: When configuring options for an NFS export, do not use the no_subtree_check
option. This option is not compatible with the StoreAll software.
Unexport the specified NFS exports:
ibrix_exportfs -U -h HOSTLIST -p CLIENT1:PATHNAME1,CLIENT2:PATHNAME2,..
[-b]
The -b option excludes the standby.
List NFS-exported directories:
ibrix_exportfs -l [-h HOSTLIST]
To specify a range of servers in the host list, enter the pattern to match, enclosed in square brackets.
Separate items in a list with commas.
Create an access entry for a file system:
ibrix_exportfs -c -f FSNAME -p CLIENT1:PATHNAME1,CLIENT2:PATHNAME2,..
By default, all StoreAll clients can mount a file system after a mount point has been created. This
command limits the clients that can mount the file system or a subdirectory of the file system. The
-p option specifies the clients and the file systems (or subdirectories) that they are allowed access.
CLIENT is the name of a StoreAll client or host group and /PATHNAME is the file system or
subdirectory the client will be allowed to mount.
For example, the following command gives client2 access to the subdirectory /ifs1/tests in
the ifs1 file system:
ibrix_exportfs -c -f ifs1 -p client2:/ifs1/tests
ibrix_exportfs
