Preparing storage for a Proxmox cluster


In this section, we need to use multiple storage devices for demonstration; please prepare the following before starting with this section. The machine requirement can be either in the physical or virtual form:

  • One machine should be installed with NAS4free with one extra hard drive as quorum

  • Three machines are needed to install Proxmox nodes for CEPH storage

  • A separate hard drive should be installed in each Proxmox node for DRBD storage

  • Three dedicated machines with one extra hard drive is needed to set up GlusterFS storage

Now, we are going to prepare the storage on the cluster environment. There are different approaches available on the market; we will create shared storage via iSCSI with the NAS4free server.

Preparing iSCSI shared storage with NAS4free for the quorum device

NAS4free is a type of software-based network storage software under the FreeBSD operation system. There are many sharing methods available, but we will focus on using the iSCSI because...
