From mboxrd@z Thu Jan 1 00:00:00 1970 From: James Simmons Date: Thu, 27 Feb 2020 16:08:07 -0500 Subject: [lustre-devel] [PATCH 019/622] lustre: hsm: ignore compound_id In-Reply-To: <1582838290-17243-1-git-send-email-jsimmons@infradead.org> References: <1582838290-17243-1-git-send-email-jsimmons@infradead.org> Message-ID: <1582838290-17243-20-git-send-email-jsimmons@infradead.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lustre-devel@lists.lustre.org From: "John L. Hammond" Ignore request compound ids in the HSM coordinator. Compound ids prevent batching of CDT to CT requests and degrade HSM performance. Use CT/archive id compatabiliy when deciding which HSM actions to put in a request.
