Storage nodes can be grouped into distinct cluster\n+groups though a single node may not be in multiple groups. For each group of\n+storage nodes:\n+\n+- A minimum of 3 storage nodes per group is required.\n+- Each storage node must have a minimum of 8 GB of RAM. This is to allow running\n+the {gluster} pods as well as other applications and the underlying operating\n+system.\n+  ** Each GlusterFS volume also consumes memory on every storage node in its\n+  storage cluster, which is about 30MB. The total amount of RAM should be\n+  determined based on how many concurrent volumes are desired or anticipated.\n+- Each storage node must have at least one raw block device with no present data\n+or metadata. These block devices will be used in their entirety for GlusterFS\n+storage. Make sure the following are not present:\n+  ** Partition tables (GPT or MSDOS)\n+  ** Filesystems or residual filesystem signatures\n+  ** LVM2 signatures of former Volume Groups and Logical Volumes\n+  ** LVM2 metadata of LVM2 physical volumes\n++\n+If in doubt, `wipefs -a <device>` should clear any of the above.\n+\n+[IMPORTANT]\n+====\n+It is recommended to plan for two clusters: one dedicated to storage\n+for infrastructure applications (such as an OpenShift Container Registry) and\n+one dedicated to storage for general applications. This would require a total\n+of 6 storage nodes.
