.New consistency group snapshot mirroring (CGSM)
Previously, disaster recovery relied on single-image mirroring between clusters. This approach supported isolated images but did not meet the needs of applications that depend on multiple volumes. For example, in a libvirt VM with several disks, each disk serves a different role. Restoring all volumes to a consistent, same-point-in-time state was challenging.
With this enhancement, consistency group mirroring in snapshot mode is now available. CGSM mirrors a group of images or volumes as a consistent set, ensuring data uniformity during recovery. The feature introduces various operations, including enabling, disabling, promoting, demoting, resyncing, snapshotting, and scheduling, which support more robust relocation, failover, and failback processes.
