Subject: [PATCH 01/26] e2e: add block device shrink and manual BlockDevice
 tests

Add three new e2e test scenarios for sds-node-configurator:
- Block device size reduction: verifies LVMVolumeGroup degrades to NotReady
  when the backing device is replaced with a smaller one
- Manual BlockDevice creation: verifies the agent deletes a fake BlockDevice
  that doesn't correspond to a real device on the node
- Manual BlockDevice modification: verifies the agent reverts manually changed
  status.size back to the real value on the next discovery scan

Also fix review findings: validate Forbidden/Invalid errors match manual
management protection (not RBAC/schema), and check size reverts to the exact
original value (not just != fakeSize).

 - Создание LVMVolumeGroup на основе BlockDevice
 - Проверка статуса и capacity
 
+### Block Device Size Reduction
+
+- Создаётся VirtualDisk, обнаруживается BlockDevice, создаётся LVMVolumeGroup, ожидается Ready
+- Оригинальный диск отсоединяется и удаляется, подключается диск меньшего размера (симуляция уменьшения устройства)
+- Проверяется, что LVMVolumeGroup переходит в состояние ошибки
+
+**Проверки**:
+- ✅ LVMVolumeGroup Phase != Ready после замены устройства
+- ✅ Conditions содержат хотя бы одну запись с status=False (VG/PV ошибка)
+- ✅ Phase в состоянии NotReady, Pending или Failed
+
+### Manual BlockDevice Creation/Modification
+
+- Пользователь создаёт поддельный объект BlockDevice вручную
+- Пользователь изменяет status.size существующего BlockDevice
+
+**Проверки**:
+- ✅ Поддельный BlockDevice (consumable=true, реальный nodeName, несуществующий path) удаляется агентом
+- ✅ API отклоняет создание, если активен validating webhook
+- ✅ Изменённый status.size восстанавливается агентом до реального значения при следующем сканировании

Subject: [PATCH 02/26] e2e: add BlockDevice disappearance scenario

Cover the case when a disk disappears after discovery by asserting the
corresponding BlockDevice is removed after detach and rescan.

Also reuse a shared helper for restarting sds-node-configurator agents in
e2e scenarios that need an immediate BlockDevice rescan.

Subject: [PATCH 04/26] ci: port e2e workflow hardening from ndemchuk branch

Port the e2e CI hardening from ndemchuk-common-scheduler-e2e-tests,
including writable Go caches, early API SSH tunnel setup, storage-e2e
bootstrap fixes, reconnect-after-add-nodes patch, and supporting e2e
manifests/docs.

Adapt the workflow to keep running TestSdsNodeConfigurator in this branch
instead of the shared TestE2E entrypoint from the source branch.

 ## What the test does
 
 - Uses the [storage-e2e](https://github.com/deckhouse/storage-e2e) framework.
-- Suite: `TestSdsNodeConfigurator` in `e2e/tests/`.
+- Entry point: `TestE2E` in `e2e/tests/e2e_suite_test.go` (single Ginkgo run: Common Scheduler scenarios first, then Sds Node Configurator — see file order / `Describe` order).
 - Covers BlockDevice discovery and LVMVolumeGroup flows on a test cluster (existing or created via framework).
 - Test cluster is reached via SSH (base cluster host or jump host) and kubeconfig (often through an SSH tunnel to the API).

+### 5. `permission denied` under `.../pkg/mod/.../storage-e2e/.../temp`
+
+The storage-e2e library writes bootstrap state under a `temp/` directory inside the **checked-out** `storage-e2e` module in the Go module cache. On self-hosted runners that cache is often under a **shared read-only** path (e.g. `/opt/.../go/pkg/mod`), so `mkdir` fails even after `chmod`.
+
+**Fix (recommended):** point the module cache at a writable directory (CI uses this):
+
+```bash
+export GOMODCACHE="$(pwd)/e2e/.gomodcache"
+export GOCACHE="$(pwd)/e2e/.gocache"
+mkdir -p "$GOMODCACHE" "$GOCACHE"
+cd e2e && go mod download && go test ...
+```
+
+**Alternative (local):** `make deps` from `e2e/` runs `fix-mod-permissions` (chmod + `mkdir` under your current `GOPATH`/`GOMODCACHE`), which helps only if that cache is writable by your user.
+
+### 6. Virtualization module stuck in `Reconciling`
+
+storage-e2e checks the Deckhouse `Module/virtualization` once with a short timeout. Before nested cluster creation (`TEST_CLUSTER_CREATE_MODE=alwaysCreateNew`), the suite polls `Module/virtualization` via the Kubernetes API until `status.phase == Ready` (uses `KUBE_CONFIG_PATH`). Override total wait with `E2E_VIRTUALIZATION_MODULE_WAIT_TIMEOUT` (e.g. `30m`). To disable this pre-wait entirely, set `E2E_SKIP_VIRTUALIZATION_MODULE_WAIT=true`.

Subject: [PATCH 05/26] e2e: add virtualization module pre-wait and increase VM
 timeout

- Add waitForVirtualizationModuleReadyIfNeeded() pre-check before
  CreateOrConnectToTestCluster to avoid failures when virtualization
  module is still Reconciling (ported from ndemchuk branch)
- Patch VMsRunningTimeout from 20m to 30m in CI to handle slow base
  cluster VM startup
- Increase go test timeout from 60m to 90m to accommodate longer waits
