Last Modified: Dec 29, 2022

Bug Tracker

Affected Product:  See more info
F5OS Velos(all modules)

Known Affected Versions:
1.5.0

Fixed In:
1.5.1

Opened: Aug 30, 2022
Severity: 3-Major

Symptoms

System controller components can hang during controller rolling upgrade, resulting in failure to start the partitions correctly, and other incorrect operation. Partition instance state may show as "failed", "offline", or "running", rather than the normal "running-active"/"running-standby". This can also cause imported ISO images to not synchronize across controllers following an upgrade.

Impact

Partition instances may not reach the normal state of running-active/running-standby, and will not operate correctly.

Conditions

Performing a system controller rolling upgrade from a version prior to 1.5.0, to version 1.5.0.

Workaround

If the system is in this state, it can be fixed by rebooting both system controllers, in sequence. Failover/go-standby is not sufficient; both controllers must be restarted to clear the issue. The problem can be avoided by performing an out-of-service upgrade, using the "out-of-service true" option with the system controller "system image set-version" command.

Fix Information

The system controller components no longer hang during the rolling upgrade.
