Pass the Ginkgo callback context to both Kubernetes API calls.
The BeforeEach callback and the final It callback can receive context.Context, as shown by neighboring tests. Pass that context through getDiskSetups and azureDataDisksByNode instead of using context.TODO() for MachineConfigs().List and Machines().Get. This preserves Ginkgo cancellation and deadlines for these requests.
A stalled request can delay this extended-test workflow until the suite timeout. The impact is limited to this workflow, so a major availability classification is not proportional.

Pass MachineConfig-derived paths as shell arguments.
partDevice comes from the decoded MachineConfig partition label and is inserted into a sh -c script without validation or quoting. A crafted label can execute additional commands in the chrooted node debug environment. The required MachineConfig and debug privileges limit practical exploitability, so this is a minor security issue.
Pass both paths as positional arguments and quote them in the script. DebugNodeRetryWithOptionsAndChroot appends these arguments after the sh -c script, which gives the script the expected $1 and $2 values.

Assert that the mount unit is enabled.
The decoder reads ign.Systemd.Units[0].Enabled, but diskSetup discards it. A correctly named but disabled unit can pass this configuration assertion.
Retain the value and require a non-nil true value.

expectedDisk does not specify a LUN. The loop derives one from setup.backingDevice and uses it to select the provider DataDisk. If both values contain the same incorrect LUN, the test can select that disk and pass the size and storage-account assertions.

The Azure multi-disk job installs a cluster with data disks configured through the machine pool diskSetup stanza and then runs 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 job would still report green. Add five tests covering the disk layout the job configures: an etcd data disk and a user-defined data disk on the control plane, two user-defined data disks on compute, and the Azure LUN, storage account type and size of each. 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, that the partition was carved out of the Azure data disk the MachineConfig targeted, and that the mount is not backed by the same device as the root filesystem, which is the failure the conformance suite cannot see. 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. The LUN is unique per machine and is what the generated device path encodes. Several Azure TechPreview jobs configure a different disk layout, including the machine-config-operator multi-disk job which declares a single etcd disk on the control plane. The tests therefore run only when the whole expected layout is present and skip otherwise, so that they describe one fixture without failing jobs that describe another. The expectations are derived from the cluster where possible: the disk label, backing device, filesystem and mount path are all read back out of the MachineConfig, so only the values the install-config chooses are pinned. Tests are tagged for both AzureMultiDisk and MultiDiskSetup, since a cluster needs both feature gates for this configuration to install. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Fail when a configured disk layout differs from expectedDisks.
This branch skips both an empty layout and a partial layout. A cluster with only one configured disk therefore skips the suite instead of reporting the contract mismatch. A cluster with the four expected disks plus an unexpected fifth disk can also pass.
Skip only when decoded is empty. If disk setup exists, compare the complete configured key set with expectedDisks and fail on missing or unexpected entries.

Adds five tests asserting that Azure data disks configured through a machine pool's
diskSetupwere actually provisioned, partitioned, formatted and mounted.Why
The Azure multi-disk job installs a cluster with data disks configured through
diskSetupand then runs the conformance suite. Nothing today asserts the diskswere set up. If the generated MachineConfig silently did nothing, etcd would keep
running on the root filesystem, every conformance test would still pass, and the
job would report green.
What the tests assert
[sig-mco][OCPFeatureGate:AzureMultiDisk][OCPFeatureGate:MultiDiskSetup] Azure machine pool disk setupTests 1–4 walk the whole chain per node: the partition exists under its label, it
holds an xfs filesystem, and that filesystem is mounted at the expected path
on a device distinct from the root filesystem.
Test 5 crosses layers: it pairs each disk-setup MachineConfig with its entry in the
Machine provider spec and checks
diskSizeGBandmanagedDisk.storageAccountType,then confirms
lsblkon the node reports a device of matching size at that LUN.Where these run
They ship in the conformance suite and run everywhere, so they gate themselves
three times, any one of which is enough:
[OCPFeatureGate:...]tags → skipped unless both gates (AzureMultiDisk and MultiDiskSetup) are enabledazure→ skip01-disk-setup-*MachineConfigs in the cluster → skipThe third is what keeps them inert on ordinary Azure TechPreview clusters: both gates are on and the platform matches, but nothing is configured, so there is nothing to assert.
Past that point the suite fails rather than skips if the layout is not the four
disks it expects. A silent skip would look like success while proving nothing. The
failure message names what the cluster actually has and calls out the drift.
Dependency
The four-disk layout is created by a paired openshift/release PR: openshift/release#85374
That PR should merge first.
