HP StoreAll Storage - Manual (Page 22)

To delete a mountpoint from specific hostgroups, use the following command:
ibrix_mountpoint -d -g GROUPLIST -m MOUNTPOINT
Viewing mountpoint information
To view mounted file systems and their mountpoints on all nodes, use the following command:
ibrix_mountpoint -l
Mounting a file system
File system mounts are managed with the ibrix_mount command. The command options and
the default file system access allowed for IBRIX 9000 clients depend on whether the optional Export
Control feature has been enabled on the file system (see
“Using Export Control” (page 24) for
more information). This section assumes that Export Control is not enabled, which is the default.
NOTE: A file system must be mounted on the file serving node that owns the root segment (that
is, segment 1) before it can be mounted on any other host. IBRIX software automatically mounts a
file system on the root segment when you mount it on all file serving nodes in the cluster. The
mountpoints must already exist.
Mount a file system on file serving nodes and IBRIX 9000 clients:
ibrix_mount -f FSNAME [-o {RW|RO}] [-O MOUNTOPTIONS] -h HOSTLIST -m MOUNTPOINT
Mount a file system on a hostgroup:
ibrix_mount -f FSNAME [-o {RW|RO}] -g GROUP -m MOUNTPOINT
NOTE: If you do not include the -o parameter, the default access option for the mounted file
system is Read Write.
Unmounting a file system
Use the following commands to unmount a file system.
NOTE: Be sure to unmount the root segment last. Attempting to unmount it while other segments
are still mounted will result in failure. If the file system was exported using NFS, you must unexport
it before you can unmount it (see
“Exporting a file system” (page 51) ).
To unmount a file system from one or more file serving nodes, IBRIX 9000 clients, or hostgroups:
ibrix_umount -f FSNAME [-h HOSTLIST | -g GROUPLIST]
To unmount a file system from a specific mountpoint on a file serving node, IBRIX 9000 client, or
hostgroup:
ibrix_umount -m MOUNTPOINT [-h HOSTLIST | -g GROUPLIST]
Enabling or disabling 32-bit compatibility mode
If clients are running 32-bit applications, you can enable 32-bit compatibility mode. This mode is
applied to the file system at mount time. You can enable or disable 32-bit compatibility on the
Modify Filesystems Properties dialog box, and can also use the following commands.
Enable 32-bit compatibility mode:
ibrix_fs_tune -c -e -f FSNAME
Disable 32-bit compatibility mode:
ibrix_fs_tune -c -d -f FSNAME
Mounting and unmounting file systems locally on IBRIX 9000 clients
On both Linux and Windows IBRIX 9000 clients, you can locally override a mount. For example,
if the Fusion Manager configuration database has a file system marked as mounted for a particular
client, that client can locally unmount the file system.
