🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Do not ignore Open vSwitch restart failures.
This restart is the cleanup fix. With || true, cleanup can return success while stale flow state remains, and the following MicroShift start can fail. Propagate the failure, or handle only a known unsupported-service case explicitly.
Proposed fix
- systemctl restart openvswitch.service 2>/dev/null || true
+ if ! systemctl restart openvswitch.service; then
+ echo "Failed to restart openvswitch.service" >&2
+ return 1

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

…-data The cleanup script stops ovsdb-server but does not restart the openvswitch service, leaving ovs-vswitchd running without its database. This stale OVS state prevents OVN from reinitializing when MicroShift is restarted, causing all pods to get stuck in FailedCreatePodSandBox.

The .local TLD is reserved for mDNS (RFC 6762) and can cause DNS interference with OVN initialization on systems with Avahi or systemd-resolved, contributing to healthcheck timeouts after hostname changes.

Summary
microshift-cleanup-data.sh. The script was stoppingovsdb-serverwithout restarting theopenvswitchservice, leavingovs-vswitchdrunning without its database. This stale OVS state prevented OVN from reinitializing on the next MicroShift start, causing all pods to get stuck inFailedCreatePodSandBox..localto.example. The.localTLD is reserved for mDNS (RFC 6762) and can cause DNS interference with OVN initialization, especially on systems with Avahi/systemd-resolved.Root Cause
Found during RC.0 release testing (PR #7284). The hostname RF test (
suites/standard1/hostname.robot) was failing in all release scenarios that use optional images (*-lrel-optional). The failure chain:microshift.localand callsmicroshift-cleanup-data --all --keep-imagesovsdb-server.service(line 106) but never restartsopenvswitch.serviceovs-vswitchdcontinues running without its databasemicroshift.servicehasWants=openvswitch.service— if systemd considers it still "active", it won't restart iterror clearing stale ovs flow targets), on bootc (readiness probe returns empty)/etc/cni/net.d/10-ovn-kubernetes.confis never created → all pods stuck inFailedCreatePodSandBoxThis was masked in non-release scenarios because those use images without optional components — fewer workloads meant the system could recover in time despite the stale OVS state.
