an LXC container environment.

apt repository. To acquire and download GPFS, follow instructions: [add link].

Creating the repositories

tar xvzf gpfs-4-1-05_ubuntu.tar.gz

Create the repository for the main packages
cd gpfs4.1/Linux/x86_64
dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz

Create the repository for the update packages
cd gpfs4.1/gpfs4.1_patches/Linux/x86_64
sudo dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz
