Last Modified: Jul 28, 2026

Affected Product(s):
F5OS Velos(all modules)

Fixed In:
F5OS-C 1.8.2-HR1, F5OS v2.0.0

Opened: Dec 04, 2025

Severity: 2-Critical

Symptoms

Tenant disk will be recreated from scratch, prompting for changing the password from the default one.

Impact

Tenant disk is lost. No way to recover it.

Conditions

When a controller is booting and is required to become the active role (including all partition active instances) due to the other controller being unavailable, a race condition may occur. This can result in the orchestration daemon removing tenant disks, as it has not have acquired the latest system state.

Workaround

Whenever possible, perform a power cycle on the controllers following a partition failover to the active controllers. Additionally, verify that there are no faults in the controller hosting the active partitions. This approach helps mitigate race conditions that may occur when the standby controller, during startup, is required to take over due to an unhealthy active controller.

Fix Information

Removed the race condition that could cause prematurely removing tenant disks.
