Offline upgrade plan for a ZCE-X Ceph cluster

Applicable scenario

• Product: ZCF
• Components: ZCE-X, Cloud
• ZCE-X version: 5.2.x
• Connected ZStack Cloud version: ZStack Cloud 4.4.x
• ZStackCube version: Upgrade ZStackCube 2.2.x to 2.4.x
• Current versions:
• ZStackCube 2.2.x
• ZCE-X 5.2.x
• Cloud 4.4.x
• qemu 4.2.x
• libvirt 4.9.x
• Target versions:
• ZStackCube 2.4.x
• ZCE-X 5.2.x
• qemu 6.2.x
• libvirt 8.0.x
• Operating system: C76
• Deployment topology: 1 cluster, 10 physical hosts, 1 primary storage
• Trigger: File storage writes are slow, and a transition upgrade to 5.2.x is required before a future V6 storage upgrade.

Symptoms

• The environment uses old versions.
• File storage writes are slow.
• The platform, virtualization components, and storage require coordinated upgrades.

Determination method

1. Before upgrade, confirm platform, Ceph, etcd, ES, Postgres synchronization, host resources, and passwordless access are normal.
