Official GlusterFS documentation suggests us use XFS for filesystem metadata storage. So, let's install it. Before we start let's take two machines ( glusterfs1, glusterfs2 ). All actions we'll do on one machine. You shoud do it on both machines. root@glusterfs1:~# apt-get install xfsprogs Specify clusters machines addresses in hosts file: root@glusterfs1:~# vi /etc/hosts glusterfs1 glusterfs2 Attach block device to your machine. Let's assume that it would be /dev/sdb. Format it with XFS. root@glusterfs1:~# mkfs.xfs -i size=512 /dev/sdb Create directory for glusterfs metad...

Volumes types: • Distributed - Distributed volumes distributes files throughout the bricks in the volume. You can use distributed volumes where the requirement is to scale storage and the redundancy is either not important or is provided by other hardware/software layers.  • Replicated – Replicated volumes replicates files across bricks in the volume. You can use replicated volumes in environments where high-availability and high-reliability are critical.  • Striped – Striped volumes stripes data across bricks in the volume. For best results, you should use striped volumes only in high concurrency environments accessing very large files.&n...
