[ceph.com, bluefs.cc] Subject: [pve-devel] [PATCH ceph squid-stable-9] bluefs: fix OSD crash caused by incorrect alignment assertion X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Reply-To: Proxmox VE development discussion Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: pve-devel-bounces@lists.proxmox.com Sender: "pve-devel" A regression was introduced in PR #62514 that added a `ceph_assert()` statement which incorrectly assumes alloc_unit is always aligned. This causes OSD crashes when the assertion fails. This cherry-pick removes the faulty assertion, resolving the crash while maintaining correct functionality for both aligned and unaligned alloc_unit values.
