21.0 revision 21.0.75.1e0880427

Released 13 Oct 2023

Introduced new feature: Erasure Coding

StorPool introduces a new redundancy mechanism called erasure coding, which can be applied on systems based on NVMe drives. It can be used as a replacement for the standard replication mechanism offered by StorPool, which would reduce the overhead and the amount of hardware needed for storing data reliably.

Migration to an erasure-coded scheme happens online without interruption in the service, and is handled by the StorPool support team for the initial conversion of a running cluster.

For more information on using erasure coding and what advantages it provides , see Erasure Coding.
Added support for Debian 12 and Proxmox Virtual Environment 8.
All services local to a node are now able to detect if their storpool_beacon service is hung.
Introduced an additional check in the update_rdma tool that the kernel modules to be reloaded exist for the running kernel.
Prevented StorPool services from using UDP port 27489 in order to prevent collisions with other services running on the node or in the storage network.
Added support for the Micron 9400 PRO.
Reduced the amount of logging from all StorPool services.
