Limitations

This page is the canonical, single-source list of what MeshStor does not support today, along with whether each item is on the roadmap, reserved for paid customers, or not planned.

About the status values:

  • Planned (open source) — on the open-source roadmap. No commitment to a date.
  • Planned (paid customers) — will be available only to paid customers. Not on the open-source roadmap.
  • Not planned — not on any roadmap.

For the broader maturity context, see Project Status.

Feature support

Feature Status Notes
Snapshots Planned (open source) Snapshot creation pays a one-time cost; per-write overhead remains zero — see Project Status
Clones Planned (open source) Same cost model as snapshots
Raw block volumes Planned (open source) Currently XFS-formatted volumes only
Ext4 filesystem Planned (open source) Currently XFS only
Encryption at rest Planned (paid customers) —
Volume expansion when drivesPerCopy ≥ 2 Planned (paid customers) Online expansion is supported today only when drivesPerCopy=1 — see Volume Expansion
KubeVirt live migration support Planned (paid customers) Multi-attach shim
Real ReadWriteMany Not planned Use a file storage system

Hard constraints

These are not limitations that can change with a software release — they are properties of the supported configuration.

Constraint Value
Access modes ReadWriteOnce (RWO) only
Filesystem XFS (Ext4 planned)
Minimum volume size 512 MiB
Drive type NVMe required (no SATA SSD or spinning disk)
Minimum node count Equal to numberOfCopies — 1 for numberOfCopies=1 (local storage mode), 2 for numberOfCopies=2, and so on

For the list of tested and planned Linux distributions, see Compatibility.
