TransferServerService::handle() returned false when the target node didn't have the resources, but threw for a state conflict on the next line down. The admin transfer action wraps the call in a try/catch and treats the happy path as unconditional, so the false slipped through and it went on to delete every backup not selected for transfer and report "transfer started". Backups aren't soft deleted and wings cleans up the files behind it, so picking an undersized node loses them with no transfer.

Throws NodeNotViableException now so callers can't ignore it. The admin action needs no change, its existing catch fires the failure notification before the deletion loop. The API branched on the bool to return a 406 and keeps that status through the exception, with a Response attribute holding onto the description in the generated spec.

TransferServerService::handle() returned false when the target node lacked
capacity but threw ServerStateConflictException on the very next line for a
state conflict, so the two failure modes signalled differently. The admin
transfer action wraps the call in try/catch and treats the happy path as
unconditional, so the false slipped through and it went on to hard-delete
every backup not selected for transfer (Backup has no SoftDeletes, and wings
cleans up the files behind it) and report "transfer started".

Throw NodeNotViableException instead so callers can't ignore it. The admin
action needs no change, its existing catch now fires the failure notification
before the deletion loop. The API branched on the bool to return 406, so it
keeps that status through the exception, with a Response attribute preserving
the "Node was not viable" description in the generated spec.

📝 Walkthrough

Walkthrough

Server transfers now throw NodeNotViableException when the destination node lacks resources. The API documents this as HTTP 406, while successful transfers return HTTP 204. Integration coverage verifies unchanged transfer state after failure.

Changes

Node transfer viability

Layer / File(s) Summary
Non-viable node exception
app/Exceptions/Http/Server/NodeNotViableException.php, lang/en/exceptions.php
Adds a translated HTTP 406 exception that includes the node name.
Transfer service failure behavior
app/Services/Servers/TransferServerService.php, tests/Integration/Services/Servers/TransferServerServiceTest.php
TransferServerService::handle now returns void and throws when the destination node lacks capacity. The integration test verifies that no transfer record is created and the server remains on its original node.
Transfer API response handling
app/Http/Controllers/Api/Application/Servers/ServerManagementController.php
Documents the 406 response and returns 204 after successful service completion without checking a boolean result.

Merge Risk: 🔵 Low · up to 85b05

A non-viable transfer may produce an incomplete error or fail while constructing the error because the node name is not selected. The change is otherwise mergeable with owner awareness and a follow-up to include the node name in the query.

Select nodes.name for NodeNotViableException.

The query omits nodes.name, but the exception reads $node->name. A non-viable transfer can therefore produce a message without the node name or trigger a missing-attribute exception when protection is enabled. Add nodes.name to the projection.
