6.2 HP IBRIX 9000 Storage CLI Reference Guide (TA768-96070, December 2012)

ibrix_exportfs
Maintains the list of NFS-exported file systems and specifies file system access for IBRIX 9000
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 IBRIX 9000
clients. By default, all IBRIX 9000 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 IBRIX
9000 client, use the -c option to create an access entry containing that information. Then, when
an IBRIX 9000 client attempts to mount the file system, IBRIX 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 IBRIX 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 IBRIX 9000 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 9000 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
