Install: Ubuntu / Debian


If you already upgraded your Chunkservers to v. 3.0.83 or higher, please DO NOT downgrade them!

In MooseFS Chunkserver v. 3.0.83 we changed Chunk header from 5k to 8k (see changelog) - it means, that Chunkserver older than 3.0.83 cannot "understand" new Chunk header, which may lead to potential data loss!

To install/update MooseFS from officially supported repository follow the instructions below:

Add the key:

# wget -O - | apt-key add -

And add the appropriate entry in /etc/apt/sources.list.d/moosefs.list:
Note: If you want to install MooseFS from moosefs-2 branch, please replace moosefs-3 with moosefs-2 in the following URLs:
After that do:
# apt-get update

and one of the following commands depending on the components that you are about to install:

Running the system

After first successful installation the system needs basic configuration. You can find more details on running the system in Documentation section available from tabs at the top of the page.

Update from previous versions

To install 2.0.x the packages from 1.6.x/1.7.x should be uninstalled without removing metadata information. It is strongly advised to backup the metadata before the update.

Once the system is running in version 2.0.x the normal update procedure from package manager should work.
