GlusterFS Basic Volumes

Distributed Volume

The default configuration Files “evenly” spread across bricks Similar to file-level RAID 0 Server/Disk failure could be catastrophic

Replicated Volume

Files written synchronously to replica peers Files read synchronously, but ultimately serviced by the first responder Copies files to multiple bricks Similar to file-level RAID 1

Striped Volumes

Individual files split among bricks (sparse files) Similar to block-level RAID 0 Limited Use Cases HPC Pre/Post Processing File size exceeds brick size
