From d8be0740a4e28b338f0b05f0c79e44a4854fec69 Mon Sep 17 00:00:00 2001 From: cgong Date: Fri, 13 Mar 2026 12:33:38 +1300 Subject: [PATCH 1/2] [SREP-3811] Add change-ebs-volume-type command for EBS volume migration Add osdctl cluster change-ebs-volume-type command that automates changing EBS volume types for control plane and infra nodes on ROSA Classic clusters. For control plane nodes, patches the ControlPlaneMachineSet (CPMS) to trigger automatic rolling replacement. For infra nodes, reuses the proven Hive MachinePool dance from the resize command. Includes pre-flight checks, confirmation prompts, rollout monitoring, and service log posting.
