Upgrading the Ceph cluster

Provisioner UI reports upgrade complete before monitoring stack upgrade finishes

When the IBM Storage Ceph Provisioner UI reports no activity and all nodes show a status of Ceph installed, the Ceph daemons on all nodes are upgraded. However, the upgrade of monitoring stack components such as alertmanager, prometheus, and grafana may still be in progress. These components are not tracked by the Provisioner UI.

To confirm that the full upgrade is complete, run the following command from the Ceph admin node:

ceph orch upgrade status

The upgrade is fully complete when the output shows:

There are no upgrades in progress currently.

As a workaround, verify the upgrade status in the Ceph Dashboard under Administration > Upgrade before concluding that the upgrade is complete.

Configuring the Ceph public network

VLAN number not applied to Ceph public network configuration during UI wizard installation

Currently, if a VLAN number is selected for the Ceph public network configuration by using the UI installation wizard, the VLAN number is not applied correctly to the Ceph public network configuration on the Ceph nodes. As a result, the Ceph public network is not configured with the correct VLAN, and the Ceph cluster installation cannot complete successfully with the intended network configuration.

As a workaround, before you trigger the Ceph cluster installation from the UI, manually add the VLAN number to each node. Connect to each node and run the following commands:

nmcli conn mod ceph-public ipv4.gateway "" ipv4.addresses "" ipv4.method disabled ipv4.dns ""
nmcli conn up ceph-public

nmcli conn add type vlan con-name vlanXXXX ifname vlanXXXX \
  vlan.parent ceph-public vlan.id XXXX vlan.flags 1 \
  ethernet.mtu 9004 ipv4.method manual ipv4.addresses "<NODE_CEPH_PUBLIC_IP>/23" \
  ipv4.gateway "<CEPH_PUBLIC_GATEWAY_IP>" ipv6.method auto
nmcli conn up vlanXXXX

Where:

  • XXXX is the VLAN number to use for the Ceph public network.
  • <NODE_CEPH_PUBLIC_IP> is the IP address of the node on the Ceph public network.
  • <CEPH_PUBLIC_GATEWAY_IP> is the IP address of the gateway on the Ceph public network.
