Apr 02, 2024
These updates fix the following issues:
- Sometimes, when XAPI attempts to write logs, it is prevented from doing so for a limited amount of time. This behavior is caused by an issue in log rotation.
- If you create a new installation of XenServer on a host with a local XFS SR on an NVMe device, your local storage does not attach on boot. The action fails with the error: “Raised Server_error(SR_BACKEND_FAILURE, [ FileNotFoundError; [Errno 2] No such file or directory: ‘/sys/block/nvme0n/queue/scheduler’ ])”. After applying this fix, you can attach the local storage manually.
