[clug] GlusterFS Vs. Ceph - High Availability Virtualization using Proxmox VE and Ceph

[George at Clug]

    I am not familiar with Ceph and only recently been learning about
GlusterFS. How does this all work? (explained simply at a high level).

High Availability Virtualization using Proxmox VE and Ceph


  USING GLUSTERFS FOR SIMPLE ISO STORAGE AND DISTRIBUTION 



	*  Ceph is not meant for file storage for things like ISO images, and
the CephFS add-on layer is still unstable but wouldn't necessarily
work for our purposes. So we decided to use GlusterFS for ISO storage.
Infact, GlusterFS has a built-in NFS server, which Proxmox prefers, so
this works out well. We shouldn't have multiple potential writers so
don't need to worry about things like split-brain multiple writers.
Most of our usage will be read-only.

They have a CEPH cluster setup with them and the CEPH S3 gateway.

Works well.
