Introduction
Installing OMV5 on Raspbian Lite, using a scripted install, is a relatively easy task. This document is a guide
for that purpose.
About this Guide
The purpose and intent of this guide is to provide a walk-through to get Raspberry Pi users (R-PI) up and
running as quickly and as easily as possible. This guide assumes that users have a working Windows Client for
installing and executing the needed utilities. It is also assumed that Mac and Linux desktop users will be able to
find, install, and use utilities equivalent to those called out in
Prerequisites.

This guide contains links to external sources of information and software. It's best used on an Internet
connected PC.

_________________________________________________
Supported Devices
OMV5 will install on R-PI models 2B and higher. In practical terms, the performance of the model 2B is
marginal.
Not Supported
Legacy Raspberry PI's
R-PI models earlier than the 2B and the R-PI Zero have
not
been tested and are
not
supported. They are far too
slow to run a NAS application. Please do not post on OMV's forum, expecting support for these models.
Wireless Interfaces
Wireless interfaces are, by default, not supported. See the
Wireless Networking
under
Final Notes.

Prerequisites
This installation process requires a wired Ethernet connection and Internet access.
Typically, all that is needed to begin the installation is an Ethernet cable, an R-PI, a power supply sufficient for
the R-PI model being used, and one SD-card (two are preferred for backup).
To get started, a few utilities are needed to check, expand, and work with the Raspbian image.
–
Raspbian images are compressed with a .zip extension. Users will need a utility like
7-Zip
to
decompress the image. 7-Zip is installable on a Windows client.
–
To check the decompressed image, an
MD5 – SHA Checksum utility
is needed. This utility is portable,
meaning it's not necessary to install it, but it may require support files. Simply run the executable.
–
SDformatter
is a utility for formatting SD-cards, that does a
trim
operation on flash media to clear
remnants of old files. SDformatter is installable on a Windows client.
–
h2testw_1.4
is a flash media test program. With a freshly formatted SD-card or USB thumbdrive, it
writes files with known content and verifies that content in a read operation, detecting errors in the
process.
h2testw_1.4
downloads as a zip file. By right clicking on the zip file, and using “Extract All”,
7-Zip will expand the zip file to a folder named
h2testw_1.4
The executable inside this folder is a
portable application. Run the executable.
–
To burn a Raspbian image to an SD-card,
Etcher
is recommended. (It burns the image and verifies it in
one process.) Etcher is a portable app. Run the executable.
–
PuTTY
is an SSH client that will allow users to connect to their SBC, from a Windows client, and get on
the command line. PuTTY is installable.
–
While 8GB is the minimum and will work fine, a 16GB card will provide longer life in the role of a boot
drive. Users are encouraged to get two SD-cards. One is for the installation and the second is for
backing up the OS installation when configuration is complete.
For the best experience, use only quality
new
SD-cards such as Samsung or SanDisk, that are rated A1,
Class 10.

**Important**
When selecting a Raspbian Image, for best possible compatibility with OMV5, don't use an image with
a desktop.
On the
Raspbian download page,
scroll down to bottom, select and download the
Raspbian Buster Lite
image.
Per the download page, the SHA-256 hash for this version of
Buster Lite
was:
9e5cf24ce483bb96e7736ea75ca422e3560e7b455eee63dd28f66fa1825db70e
(** The hash number will change with the image, as images are updated. **) Make a note of the hash
number found, or bookmark the download web page for reference. This will be used later.

Working With The Image File
Verify the Archive file
After downloading the Buster Lite archive, MD5 and SHA hashes check for file corruption that may have
occurred during the download.
The Raspberry PI project provides a
SHA-256
hash check number for the downloaded Zip archive file.
**Beginners Note**
DO NOT SKIP THIS STEP.
The chance of corruption is highest when downloading and it's pointless to build
a server with flawed software. Even the slightest amount of corruption may ruin your installation and the
effects may not be noticed until well after your server is built and in use. Headaches can be avoided by
checking the zip archive.
__________________________________________________
Verify the downloaded Zip file with the
MD5 & SHA checksum utility.
(Note that it's possible to “drag and drop” the file name into the utility, on the
File
line. Otherwise, use the
Browse
button and navigate to the compressed image file.)
With the previously noted down SHA-256 hash, or by referencing the
Raspbian Web page,
compare the utility's
result with the SHA-256 hash provided on the download page.
In this specific case it's:
9e5cf24ce483bb96e7736ea75ca422e3560e7b455eee63dd28f66fa1825db70e
With a SHA-256 match, the downloaded file is verified.
