Harmonic MediaGrid Release 4.1
Installing the Harmonic MediaGrid File System Driver for Linux
Installing the Linux FSD for the First Time
Prior to installing the Harmonic MediaGrid FSD for Linux, make sure of the following:
No application is running on the computer.
All Harmonic MediaGrid file systems are unmounted, using the “
umount
” Linux command. If
installing the Harmonic MediaGrid FSD for Linux from a network location, copy the installation
file to a local directory before beginning the installation.
Any prior releases of the Linux FSD are unloaded, by using the “
rmmod
” command:
rmmod omfs
To install the Linux FSD for the first time:
1. Use one of the following commands to install the selected rpm file for the first time:
For RedHat Fedora, use the “rpm –i” command with the “--force” option. For example:
# rpm –ivh --force MediaGridFSD-3.5.0.0-20070515_2.6.17_1.2142_
FC4smp.x86_64.rpm
For Ubuntu or Debian use:
dpkg --install --force-overwrite mediagridfsd_3.5.0.0-20140512-3.2.0-
29-generic_amd64.deb
The "--force-overwrite" option replaces the distro-provided omfs.ko module. See the note
below.
For all other Linux operating systems you may use the “rpm --i” command by itself. For
example:
# rpm –ivh MediaGridFSD-3.5.0.0-20070515_2.6.17_1.2142_FC4smp.
x86_64.rpm
2. Please capture the output of the above command in case a problem occurs.
3. Once you have installed the rpm file, restart your client computer.
NOTE:
Fedora, SLES, Ubuntu, and Debian distributions provide an "omfs.ko" kernel driver module which
conflicts with the Harmonic Mediagrid kernel driver module of the same name. In most cases, this is not
automatically loaded nor needed. However, you should ensure it is not already in use before replacing it
(for example, the command "lsmod | grep omfs" can be used to determine if it is loaded into the kernel).
The Harmonic MediaGrid file system can now be mounted. Refer to
for instructions on mounting Harmonic MediaGrid file systems from a Linux
computer.
Installation Issues
If the rpm utility complains about a dependency mismatch, particularly about a kernel module,
please check the kernel revision level on the computer against the kernel levels listed above
against each distribution. There may be a mismatch between the kernel that the rpm is built for
and the one on the machine. If this is the case, please contact Harmonic Technical Support for
assistance or a revised rpm package.
Upgrading From a Prior Release
Before upgrading the Harmonic MediaGrid Linux FSD software, make sure that:
No application is running on the computer.
