The E2E sandbox tenant (tenant-test) provisions back-to-back tenant
Kubernetes control planes via kubernetes-latest.bats and
kubernetes-previous.bats. Each control plane brings up two worker VMs
whose 20Gi root disks are populated by CDI, and CDI's second-phase
importer allocates a scratch PVC of the same size before the qcow2
unpack. Peak per-tenant footprint is therefore ~82Gi during import
(2 × 20Gi target + 2 × 21Gi scratch), collapsing to 40Gi at rest.
kubernetes-latest teardown deletes the tenant Kubernetes CR and waits
via cozy_wait_tenant_drained for the KubeVirt VMs, VMIs and namespace
PVCs to disappear. The API-level PVC delete returns quickly, but the
LINSTOR CSI detach + DRBD resource release on the underlying nodes
lags past the 300s drain budget. During that window, the deleted
PVCs still count against ResourceQuota's requests.storage because
the storage-provisioner has not finished releasing the volume — so
kubernetes-previous starts its own CDI import with 40Gi of stale
kubernetes-latest quota still charged, and CDI's scratch PVC create
for the second worker (used=80Gi + scratch=21Gi = 101Gi) is
rejected by the tenant-quota admission check at 100Gi. The second
worker's DataVolume never leaves ImportInProgress, the tenant node
never joins, and the 12-minute node-join deadline in
run-kubernetes.sh trips kubernetes-previous.bats.
Raise the sandbox tenant-quota storage ceiling to 200Gi so the
overlap between one test's slow storage cleanup and the next test's
CDI import fits inside the quota. The failing-run diagnostic is
cozyreport artifact from run 28730757213:
cdi-deployment log:
scratch PVC API create errored: … forbidden: exceeded quota:
tenant-quota, requested: requests.storage=22763536384,
used: requests.storage=85899345920,
limited: requests.storage=100Gi
This is a test-infrastructure fix; the 100Gi default in the tenant
chart itself is unchanged. The assertion below the CR update is
lifted from 100Gi to 200Gi in lockstep.
