* Host HA code improvements
* Fix to not cancel VM HA items when Host HA is enabled & inspection in progress, and some code improvements
- When Host HA inspection in progress, the investigor returns the Host Status as Up which cancels the VM HA items
- Don't cancel the VM HA items, instead reschedule them to try again later
* Changes to consider Recovered/Available Host HA state along with the agent connection status to determine the Host HA inspection in progress or not, and some code improvements
* Linstor: fix create volume from snapshot on primary storage
When creating a volume from a snapshot on Linstor primary storage
(with lin.backup.snapshots=false), the operation fails with:
"Only the following image types are currently supported: VHD, OVA,
QCOW2, RAW (for PowerFlex and FiberChannel)"
Root cause: the Linstor driver does not handle SNAPSHOT -> VOLUME in
its canCopy()/copyAsync() methods. This causes DataMotionServiceImpl
to fall through to StorageSystemDataMotionStrategy (selected because
Linstor advertises STORAGE_SYSTEM_SNAPSHOT=true). That strategy's
verifyFormatWithPoolType() rejects RAW format for Linstor pools,
since RAW is only allowed for PowerFlex and FiberChannel.
Additionally, VolumeOrchestrator.createVolumeFromSnapshot() attempts
to back up the snapshot to secondary storage when the storage plugin
does not advertise CAN_CREATE_TEMPLATE_FROM_SNAPSHOT. This backup
fails because the snapshot only exists on Linstor primary storage.
Fix:
- Add CAN_CREATE_TEMPLATE_FROM_SNAPSHOT capability so the
orchestrator skips the backup-to-secondary path
- Add canCopySnapshotToVolumeCond() to match SNAPSHOT -> VOLUME
when both are on the same Linstor primary store
- Wire it into canCopy() to intercept at DataMotionServiceImpl
before strategy selection, bypassing StorageSystemDataMotionStrategy
- Implement copySnapshotToVolume() which delegates to the existing
createResourceFromSnapshot() for native Linstor snapshot restore
This follows the same pattern used by the StorPool plugin, which
handles SNAPSHOT -> VOLUME directly in its driver rather than going
through StorageSystemDataMotionStrategy.
Tested on CloudStack 4.22 with Linstor LVM_THIN storage, creating
a volume from a 1TB CNPG Postgres database snapshot. Volume creates
successfully with correct path and deletes cleanly.
* Let CloudRuntimeException propagate from copySnapshotToVolume
Remove try/catch in copySnapshotToVolume so that CloudRuntimeException
from createResourceFromSnapshot propagates to the caller, ensuring
CloudStack properly notices and reports the failure.
* Fix CAN_CREATE_TEMPLATE_FROM_SNAPSHOT breaking template creation
Setting CAN_CREATE_TEMPLATE_FROM_SNAPSHOT unconditionally to true
caused createTemplate from snapshot to take the StorPool-specific
code path in TemplateManagerImpl, which sends a CopyCommand to a
system VM that Linstor cannot handle.
Fix: make CAN_CREATE_TEMPLATE_FROM_SNAPSHOT conditional on the same
flag as STORAGE_SYSTEM_SNAPSHOT (!BackupSnapshots). When snapshots
are backed up to secondary (the default), the old template creation
flow works. When snapshots stay on primary, the direct path is used.
Also fix checkstyle: remove unused DataObject import in test.

* Linstor: Refactor resource creation methods to LinstorUtil
Move reusable methods from LinstorPrimaryDataStoreDriverImpl to LinstorUtil
to enable sharing with other components:
- logLinstorAnswer, logLinstorAnswers, checkLinstorAnswersThrow
- getRscGrp, getEncryptedLayerList, applyQoSSettings
- createResourceBase, createResource, spawnResource
- canShareTemplateForResourceGroup, foundShareableTemplate
Add LIN_PROP_DRBDOPT_EXACT_SIZE constant and exactSize parameter support
for DRBD exact-size property handling during resource creation.
* Linstor: Add LinstorDataMotionStrategy for VM live migration
Implement DataMotionStrategy for live migration of VMs with volumes on
Linstor or other primary storage.
Key features:
- Support live migration with storage from other primary storages
- Preserve DRBD exact-size property during migration
* Migrate volume improvements, to bypass secondary storage when copy volume between pools is allowed directly
* Bypass secondary storage for copy volume between zone-wide pools and
- local storage on host in the same zone
- cluser-wide pools in the same zone
* Bypass secondary storage for volumes on ceph/rdb pool when the scope permits
* Fix dest disk format while migrating volume from ceph/rbd to nfs, and some code improvements
* unit tests
* Update suitable disk offering(s) for volume(s) after migrate VM with volumes when change in pool type (shared or local)
Currently, Migrate VM with volume(s) bypasses the service and disk offerings of the volumes, as the target pools for migration are specified,
which ignores the offerings. Offering change is required when pool type (shared or local) is changed, mainly
- when volume on shared pool is migrated to local pool
- when volume on local pool is migrated to shared pool
* Update with proper message while migrate volume when target pool and offering type mismatches (both are not shared/local)
* Consider host scope first during endpoint selection while copying between primary storages
* Update disk offering count (for listDiskOfferings api) while removing offerings with tags mismatch with storage tags
We didn't account for caching the volume stats for each used Linstor
cluster, so the first asked Linstor cluster would prevent caching
for all the others and so null was returned.
Now we have invalidate counters for each Linstor cluster and
also store the cache result with the Linstor cluster address prefixed.
* Introducing Storage Access Groups to define the host and storage pool connections
In CloudStack, when a primary storage is added at the Zone or Cluster scope, it is by default connected to all hosts within that scope. This default behavior can be refined using storage access groups, which allow operators to control and limit which hosts can access specific storage pools.
Storage access groups can be assigned to hosts, clusters, pods, zones, and primary storage pools. When a storage access group is set on a cluster/pod/zone, all hosts within that scope inherit the group. Connectivity between a host and a storage pool is then governed by whether they share the same storage access group.
A storage pool with a storage access group will connect only to hosts that have the same storage access group. A storage pool without a storage access group will connect to all hosts, including those with or without a storage access group.
Somehow deleteDatastore was never implemented, that meant:
templates haven't been cleaned up on datastore delete and
also agents have never been informed about storage pool removal.
If a -rst resource wasn't deleted because of a failed copy,
a reoccurring snapshot attempt couldn't be done, because there
was still the "old" -rst resource. To prevent this always
try to remove the -rst resource before, if it doesn't exist it is a noop.
