Encrypted Linstor volumes use a LUKS layer inside the DRBD stack, so
the storage-layer snapshot device holds ciphertext while the DRBD
device CloudStack restores to is the decrypted view. Backing up the
raw snapshot and writing it back to the decrypted device corrupted the
volume (different data, unbootable root).
Back up encrypted snapshots from the decrypted DRBD device (forcing
the temporary-resource path) and store them as a LUKS-encrypted qcow2
using the volume passphrase, so snapshots are not kept in clear text
on secondary storage. On revert, decrypt the qcow2 and write plaintext
to the DRBD device; the LUKS layer re-encrypts it. The qemu-img shrink
is skipped for encrypted volumes (the DRBD device is already
net-sized).
Add an integration test (test_linstor_encrypted_snapshots.py): the
encrypted-root snapshot revert round-trip, that
create-volume-from-encrypted-snapshot is rejected by CloudStack core,
and a best-effort check that the backed-up qcow2 is LUKS-encrypted at
rest.

* linstor: update java-linstor to 0.7.0 to support auth token api
With Linstor 1.34.0 a new authentication mode is supported:
* Bearer token
To support that it had to be implemented in the java-linstor library
and we need to store the auth token per storage pool.
Also per default with this auth mode Linstor will run with
HTTPS enabled, so we also have to support that.
* ui: seed default-on toggles in zone wizard while hidden
StaticInputsForm.fillValue() only seeded defaults for currently-displayed
fields, so a display-gated switch with checked:true bound to an undefined
value and rendered as off once revealed. Seed checked switch/checkbox
fields even while hidden, so the Linstor 'Allow self-signed certificate'
toggle defaults on in the zone creation wizard.
This PR enhances the existing CLVM implementation which was based on the deprecated CLVM technology which was based on corosync/pacemaker. With RHEL 7 having reached EOL, CLVM seems to be broken. CLVM supports RAW volumes on LVM , where as CLVM_NG support QCOW2 on LVM.
Further details: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Modernized+CLVM%3A+Enhancements+and+CLVM_NG+support
NOTE: On testing - it was identified that incremental snapshots for clvm-ng do not work as expected. As of now it's been removed from scope. So, CLVM and CLVM_NG would only support full snapshots.

* improve lock host retrieval logic and quicker retrival using db host as first check point and then fanning out
* add proper support for resizing of clvm_ng which calculated PE correctly for qcow2 metadata
* fallback to full snapshots for clvm-ng - incremental not supported in 4.23
* expunge volume detail of lock host on vm expunge
* if vmmigration with volume is done to the same clvm volume group, then dont do data transfer, just lock transfer and vm
* add clvm pools with deterministic uuid , so as to prevent adding the same pool twic
* added a small improvement to factor in a senario when lv is inactive on all hosts, could happen in storage outage issue
* address comment - extract common code for endpoint identification if clvm pool type
* Address comments - add early return guard to reduce indentation
* minor improvement - when migrating vm with volumes, if there's a failures, change the clvm vols to exclusive on source from shared, and on success, change dest vol to exclusive only for cross-pool migration
* cleanup unused code and tests for incremental snaps for clvmng and other cleanups
* allow storage browser to list lv in clvm, fix clvm shrink, overprovisioning factor isnt used for clvm pools - so set it to 1 and prevented display of provisioning type for clvm
* no need to have locktransfercommand to execute in sequence
* increase lv cmd timeouts to consider cluster load

* Host HA code improvements
* Fix to not cancel VM HA items when Host HA is enabled & inspection in progress, and some code improvements

* 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.
