A final project for the Gvahim program. This project offers a system that can store your data on multiple servers, and back them up based on the RAID5 protocol (Redundant Array of Independent Disks). The system lets you manage your servers, and works perfectly even with one faulty block device.

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Here are the things you will need to download in order to get this system up and running:

1) Download and install Python2.7
2) Download this repository on your machine (Windows coming soon)
3) Download and install any modern browser
4) Download and instal Cygwin64 (for Windows users)

Chrome: By default, chrome doesn't save form data upon refresh. Therefore on "Manage Disks", the refresh time might not be sufficient for user purposes. Looking into solutions.

Firefox: Firefox currently disables basic authentication so could be problematical and will need to add this option manually. This can be done in the about:config section of firefox. Looking into better solutions

Running the servers can be done as follows:For Linux:

Reach parent directory (RAID5)

cd [location of RAID5]

Running Frontend Server:

python -m frontend [args]

Running Block Device Server:

python -m block_device [args]

Testing the servers can be done from any browser. Basic Authentication is required with common_user and common_password specified in frontend/config.ini.

In both the Frontend and the Block Devices, the configuration file needs to be specified as args. The Block Devices also require a bind port as shown below:

python -m frontend --config-file frontend/config.ini
python -m block_device --config-file block_device/disks/config0.ini --bind-port 8090
python -m block_device --config-file block_device/disks/config1.ini --bind-port 8091

Note: All other Arguments are optional, see --help for help

Note: Default configuration files are provided in this repository. The configuration files can be created from scratch (new UUIDs and such) by a python script from the parent directory (RAID5):

python config_disks.py <NUM_OF_BLOCK_DEVICES>

Note: UUID's can be changed manually from the configuration files

Another python test script from the parent directory (RAID5), has also been provided, that writes to the first disk (disk0) a long sequence of numbers, for testing purposes:

python test.py
