Subject: [pve-devel] [PATCH ha-manager v2 16/26] sim: resources: add option to limit start and migrate tries to node
Date: Fri, 20 Jun 2025 16:31:28 +0200 [thread overview]
Message-ID: <20250620143148.218469-21-d.kral@proxmox.com> (raw)
In-Reply-To: <20250620143148.218469-1-d.kral@proxmox.com>
Add an option to the VirtFail's name to allow the start and migrate fail
counts to only apply on a certain node number with a specific naming
scheme.
This allows a slightly more elaborate test type, e.g. where a service
can start on one node (or any other in that case), but fails to start on
a specific node, which it is expected to start on after a migration.
Signed-off-by: Daniel Kral <d.kral@proxmox.com>

changes since v1:
- make check if retries should be done for node simpler from a regex
to a string comparison
- inline `$should_retry_action->(...)` in if statements
