What IS XtreemFS?

XtreemFS is a fault-tolerant distributed file system. It is an open-source file-system that is distributed with support for client and servers from any location and connected together using the internet. It is characterized by it’s:

1. Versatility :- XtreemFS is a general purpose storage system and covers most storage needs in a single deployment. It is an open-source technology that do not require any special hardware or kernel modules and it can be mounted on Linux, Windows and OS X machine.

2. Reliability :- XtreemFS is the only fault-tolerant file system that automatically handles all failure modes, including network splits. Fault-tolerant replication keeps your data safe and gives you peace of mind.

3. Scalability :- XtreemFS is scalable you can scales it according to your needs within a minutes, simply by adding new standard hardware. You can start with a single server, growing to a cluster and across datacenters.

XtreemFS Installation

On Ubunt/Debian System

To add XtreemFS repository edit the /etc/apt/sources.list file on Debian or Ubuntu system like below:

# deb http://download.opensuse.org/repositories/home:/xtreemfs/xUbuntu_16.04 ./

Replace URL of the repository for your distribution. In my example the packet source is used for the “Ubuntu 16.04”. Appending ./ to the URL is must.

Now add the package signing key of your repository to your system.

# wget -q http://download.opensuse.org/repositories/home:/xtreemfs/xUbuntu_16.04/Release.key -O - | sudo apt-key add -

Update the package lists.

# apt-get update

Now install the client or server packages:

# apt-get install xtreemfs-client
# apt-get install xtreemfs-server

On CentOS/RHEL/Fedora System

For CentOS/RHEL/Fedora system you have to download the XtreemsFS repository into /etc/yum.repos.d/ location on the system.

For example add the XtreemFS repository On CentOS 6 as follows:

# cd /ect/yum.repos.d/
# wget "http://download.opensuse.org/repositories/home:/xtreemfs/CentOS_7/home:xtreemfs.repo"

Now install the client or server packages:

# yum install xtreemfs-client
# yum install xtreemfs-server

XtreemFS Service And Modules

XtreemFS is based on three services and kernel module called fuse:

Dir – Directory Service : It is used by the MRC, OSD and client to find other servers, resolve UUID mapping and volume names.

MRC – Metadata and Repica Catalog : It stores the volumes with their directory tree and all metadata for files in the volumes.

OSD – Object Storage Device : It is not a special device it is regular server, these servers store the file content and implement the replication.

FUSE – File-system in Userspace : It is a kernel module that simplifies the development of new file systems.

Mounting XtreemFS

To mounting XtreemFS fist start the directory service typing below command:

# /etc/init.d/xtreemfs-dir start

Start Metadata server:

# /etc/init.d/xtreemfs-mrc start

Start the OSD:

# /etc/init.d/xtreemfs-osd start

Load the Fuse kernel module if not loaded.

# modprobe fuse

Create a new volume with it default setting:

# mkfs.xtreemfs localhost/Volume

Create a mount point:

# mkdir ~/xtreemfs

Mount XtreemFS on your system:

# mount.xtreemfs localhost/Volume ~/xtreemfs

That’s it now you can use your volume.

Unmounting XtreemFS

Type the below command to unmount the XtreemFS:

# umount.xtreemfs ~/xtreemfs
