Reject LUN values that do not fit in int32.
backingDevice comes from the decoded MachineConfig without a range check. On 64-bit systems, strconv.Atoi accepts values larger than int32; converting such a value can wrap it into an expected LUN, such as 4294967296 becoming 0. This can make the LUN assertion match the wrong device.
Parse with a 32-bit limit before conversion.
Proposed fix

+ lun, err := strconv.ParseInt(strings.TrimPrefix(d.backingDevice, azureLunDevicePrefix), 10, 32)

Propagate the active spec context to the node request.
context.TODO() prevents cancellation when the spec times out or the suite stops. A stalled API request can keep the parallel test running until an external timeout.
Add ctx context.Context to getNodesWithRole and pass it to Nodes().Get. Propagate the spec context from each caller.

openshift/release ci-operator/step-registry/ipi/conf/azure/multidisk install-config data disks
💡 Result:
<search_synthesis>
The OpenShift CI-operator step registry path ipi/conf/azure/multidisk is associated with infrastructure-provisioned (IPI) Azure configuration [1][2]. The ipi-conf-azure step, often used within CI chains (e.g., ipi-azure-pre), is responsible for generating the Azure-specific sections of the install-config.yaml file based on cluster profiles and optional inputs [1][3][4]. Regarding the specific configuration of additional data disks on Azure, recent developments in the OpenShift installer have introduced support for defining data disks directly within machine pools [5][6]. Key points regarding Azure data disk configuration in OpenShift: 1. New Data Disk Support: OpenShift has introduced a dataDisks field within the machinePool specification for Azure [5][6]. This allows users to add additional managed disks at installation time [5]. 2. Implementation via MachineConfig: While the installer allows defining these disks in the install-config.yaml [7][6], the underlying setup often leverages ignition-based disk provisioning via MachineConfig [6]. This includes capabilities to format, mount, and configure these disks (e.g., for etcd or swap) [7][6][8]. 3. Configuration Structure: The dataDisks configuration typically includes parameters such as: - nameSuffix: A suffix to identify the disk [7][6]. - diskSizeGB: The size of the disk in gigabytes [7][6]. - managedDisk: Storage account type (e.g., PremiumV2_LRS) [7]. - lun: The logical unit number (LUN) for the disk [7][6]. - cachingType: Disk caching configuration (e.g., None) [7]. 4. Feature Gates: The multi-disk functionality is often controlled by specific feature gates (e.g., MultiDiskSetup) and requires appropriate cluster configuration to enable [5][6]. Note: The ipi-conf-azure step registry entry itself primarily focuses on generating the core install-config.yaml structure [4], while the actual declaration of data disks is handled through the machine pool and machine config mechanisms facilitated by the installer [5][6]. Detailed documentation on specific parameters for Azure installation configuration can be found in the official OpenShift documentation for your version [9].

Skip layouts that contain additional disk setups.
When all four expected role/mount keys exist, missing stays empty. A valid Azure layout with an additional distinct setup then reaches this length assertion and fails instead of being skipped. Replace the assertion with a skip for layouts whose size differs from expectedDisks.

util-linux lsblk official man page PKNAME parent device top-level no parent
💡 Result:
<search_synthesis>
In the util-linux lsblk command, PKNAME stands for "parent kernel device name" [1][2]. It displays the name of the device that acts as the parent of the current block device in the system's hierarchy [2][3]. Key behaviors of PKNAME include: 1. Hierarchy Dependency: PKNAME is fundamentally based on the block device tree [4][3]. Because the tree structure is optional and often not generated when a specific device is targeted (e.g., lsblk /dev/sda1), the field may appear empty if the tool cannot resolve a parent context [4][5]. 2. Top-Level Devices: If a device is a top-level device (such as a physical disk like /dev/sda) and has no parent, the PKNAME column will be empty [4][5]. 3. Partitions: For partitions, lsblk is generally designed to associate them with their parent disk. Even when targeting only a partition, recent versions of util-linux include logic to force the identification of the parent device to ensure PKNAME remains populated [4][3]. 4. Complex Devices: For devices with multiple parents (such as certain RAID, Multi-path, or LVM configurations), PKNAME may not be reliably determined or displayed if the device is queried in isolation, as the "correct" parent depends entirely on the specific branch of the hierarchy being examined [5]. In summary, when PKNAME is empty, it typically indicates that either the device is at the top of its hierarchy (no parent) or that the tool lacks sufficient tree context to associate it with a specific parent [4][5].

Do not skip the root-device separation check.
collectNodeDiskState stores rootParent only from lsblk PKNAME output for rootSource. A top-level root device has no parent name, so a valid response can leave rootParent empty. The condition then skips this comparison, even when the data partition uses that same physical device.
Resolve rootSource to its top-level physical device. If resolution fails, return an error instead of treating the missing parent as a successful check. Treat rootSource itself as the parent when it is already a top-level physical device.

storage account is an azure specific thing, do you think we will use expectedDisk into another provider tests as well?
There was a problem hiding this comment.
We cannot as there are several azure-specific assertions and parameters (e.g. the lun). However I will refactor to clarify with variable name and function names what is azure specific, so that it could make the code slightly more code readable and possibly extensible in future to add similar tests for other providers.

What do you think adding a custom suite triggered by release PR/job only for multi-disk, with qualifiers filtering something like OCPFeatureGate:MultiDiskSetup?
There was a problem hiding this comment.
I thought of using the conformance suite so that we can also assess that the cluster actually works with multi disk configured, not just that the disks are mounted and formatted. The drawback is that the steps run and skip on every azure cluster even those without multi disk. I considered adding a Ginkgo label and a filter to target only clusters with the two feature gates, but this would inject a filter in the entire suite. I'd probably just hold off and skip the test if not applicable, which should not really create much overhead anyway I believe. If you prefer, I can go down the Ginkgo label + feature gate filter approach though.

The Azure multi-disk jobs install a cluster with data disks configured through the machine pool diskSetup stanza and then run the conformance suite. Nothing asserts that the disks were actually set up: if the generated MachineConfig silently did nothing, etcd would keep running on the root filesystem and the jobs would still report green. Add a non-disruptive suite parented to openshift/conformance/parallel. The two existing suites are both disruptive and run on a scheduled basis, so read-only tests had nowhere to live that runs alongside ordinary conformance. Parenting there also means the job keeps proving that a cluster with relocated etcd, container and kubelet storage still passes conformance, not merely that the disks are mounted. Add six tests covering the disk layout the multi-disk jobs configure: an etcd data disk and a user-defined data disk on the control plane, two user-defined data disks on compute, the rendering of each disk setup into its MachineConfigPool, and the Azure LUN, storage account type and size of each disk. Each test walks the whole chain rather than a single link, checking that the partition exists under its expected label, that it holds an xfs filesystem mounted with prjquota at the configured path, and that the partition was carved out of the Azure data disk the MachineConfig targeted. The root filesystem is not consulted: on RHCOS it is a composefs overlay with no backing block device, and the separation from the OS disk is already guaranteed by partitioning a /dev/disk/azure/scsi1/lun<N> path. Disk setups are paired with their data disks by LUN. The partition label cannot be used for this: the installer labels etcd and swap partitions with the disk setup's type rather than its platformDiskID, and strips every non-alphanumeric character from the result, so it does not generally equal the data disk's nameSuffix. Keep the Azure-specific parts together behind azureExpectedDisk and assertAzureDataDisk, so that the MachineConfig decoding and node inspection could serve another platform unchanged. Disk setup is opt-in and the layout differs between jobs, so the tests run only when the whole expected layout is present and skip otherwise. The tests are labelled Platform:azure, which the extension's existing label filter turns into an environment selector, so they are never scheduled off Azure.

Adds six tests asserting that data disks configured through a machine pool's
diskSetupstanza are actually provisioned, partitioned and mounted.Why
This repo's
e2e-azure-ovn-multidisk-techpreviewjob installs a cluster with datadisks and runs conformance. It asserts nothing about the disks, if the generated
MachineConfig did nothing, etcd would run on the root filesystem and the job would
still be green. This PR adds tests that verify the provisioned disks on both master and worker nodes under different configurations.
What
Suite. The two existing suites are disruptive and scheduled, so read-only tests
had nowhere to run alongside conformance. For this reason PR adds
openshift/machine-config-operator/parallel, parented toopenshift/conformance/parallelas suite for the new tests.Tests.
test/extended/disksetup.go, labelledPlatform:azure. Each walks the whole chain: partitionexists under its label, holds xfs, is mounted at the expected path, was carved out
of the Azure data disk the MachineConfig targeted, and is not on the root device.
They run only when the full expected layout is present and skip otherwise, so they
stay inert on Azure jobs configured differently or with no disk setup at all.

Paired release PR creates that layout and must merge first: openshift/release#85374
