6.5 HP StoreAll OS CLI Reference Guide

ibrix_mount
Mounts a file system on file serving nodes and StoreAll clients.
Description
When mounting a file system on specific file serving nodes, the first file serving node listed must
own the root segment (segment 1). StoreAll software automatically mounts on the root segment
first if you mount on all file serving nodes in the cluster.
Mounts are immediately executed for file serving nodes. For StoreAll clients the mount intention is
stored in the Fusion Manager. When StoreAll software services start on a StoreAll client, the client
queries the Fusion Manager for the file systems that it should mount and mounts them. If StoreAll
software services are already running on the StoreAll client when you set new mounts, you can
force the client to query the Fusion Manager by running ibrix_client or ibrix_lwmount
-a on the StoreAll client, or by rebooting it.
When mounting a file system where Export Control is enabled, you must specify that all clients
have either RO or RW access to the file system. The default is RW (Read Write). In addition, the
root user can be restricted to read-only access on export-controlled systems in a host group by
adding the root_ro parameter to the ibrix_mount command.
Mount points must be defined with ibrix_mountpoint before running ibrix_mount.
IMPORTANT: Keep in mind:
• Mount options do not persist, unless they are set at the mountpoint. Mount options that are
not set at the mountpoint are reset to match the mount options on the mount point when the
file system is rebooted or remounted.
• The ibrix_fs —i and ibrix_mountpoint —l commands display only the mount options
for the mount point.
• The mount command displays the noatime option. Ignore the noatime option. It is no longer
used. If you set the atime option, the atime option will display instead of the noatime option
when you run the mount command.
Synopsis
Mount a file system on file serving nodes and StoreAll clients:
ibrix_mount -f FSNAME [-o {RW|RO}] [-O MOUNTOPTIONS] [-h HOSTLIST] -m
MOUNTPOINT
The file system is mounted at the specified mountpoint on the file serving nodes and StoreAll clients
specified in HOSTLIST. The first file serving node listed must own the root segment in the file
system. To mount on all file serving nodes and StoreAll clients, omit the HOSTLIST option. If Export
Control is enabled, you must specify RW or RO file system access.
Mount a file system on host groups:
ibrix_mount -f FSNAME [-o {RW|RO}] [root_ro] [-O MOUNTOPTIONS] -g
GROUPLIST -m MOUNTPOINT
The file system is mounted at the specified mountpoint on the host groups specified in GROUPLIST.
If Export Control is enabled, you must specify RW or RO file-system access. The optional root_ro
parameter specifies that the root user be limited to read-only access on the systems in the host
group.
Export Control Examples
The following command mounts file system ifs1 on all file serving nodes and StoreAll clients at
mountpoint /ifs1 and gives the clients RW access:
<installdirectory>/bin/ibrix_mount -f ifs1 -o RW -m /ifs1
