GlusterFS combines disks from multiple servers into a shared filesystem that applications can access as one storage space. It is useful when workloads need shared files rather than separate local disks, with replication and placement handled by the storage system. This entry concerns the older Kubernetes integration as well as Gluster itself. Those lifecycles differ: an existing storage system may still run even though a newer Kubernetes release cannot use its old volume definition.
Deployment and operating notes
The recovered page points to gluster-kubernetes and its Heketi-based provisioning model. Kubernetes documentation records removal of the in-tree GlusterFS volume type in Kubernetes 1.26. That is a concrete compatibility boundary for old PV specifications, independent of whether a separate GlusterFS storage system continues to operate.
Before upgrading an affected cluster, inventory Gluster-backed PVs, endpoints, Heketi metadata, volume IDs, mount options and application access patterns. Establish a supported storage path for the target Kubernetes release rather than assuming a CSI driver will adopt the old volumes automatically. A migration may require data copying to another shared filesystem or storage service while preserving ownership, permissions and application consistency. Rehearse the copy and a restore with a representative workload, then schedule a write freeze or synchronization plan. Keep the original volumes protected until data and application checks pass. Recreating claims or changing a StorageClass name does not move data, and deleting the old provisioner can complicate later recovery.
Historical upstream link check · 2026-10-09
The recorded upstream address responded successfully (HTTP 200) on 2026-10-09. GitHub marks gluster/gluster-kubernetes as archived. This confirms the repository's read-only archive state; any successor or supported distribution needs separate evidence. Link availability does not certify the historical installation instructions or current security support.

Gluster is a scalable, distributed file system that aggregates disk storage resources from multiple servers into a single global namespace.
Advantages
- Scales to several petabytes
- Handles thousands of clients
- POSIX compatible
- Uses commodity hardware
- Can use any ondisk filesystem that supports extended attributes
- Accessible using industry standard protocols like NFS and SMB
- Provides replication, quotas, geo-replication, snapshots and bitrot detection
- Allows optimization for different workloads
- Open Source
Unfortunately, there is currently no Helm chart for Gluster. You’ll need to use the gluster-kubernetes repository to install it.
