Data on MDT

New Feature Major Resolved Fixed Mikhail Pershin Mikhail Pershin Tue, 7 May 2013 03:25:41 +0000 Sat, 3 Jul 2021 01:35:31 +0000 Wed, 29 Nov 2017 17:54:26 +0000 Lustre 2.7.0 Lustre 2.11.0 0 13 <p>This feature needs to have an OBD_CONNECT flag to indicate that the client and server support it. One option is to use the <tt>OBD_CONNECT_REQPORTAL</tt> feature on the MDS connection, since that was used in the past to add a separate IO portal on the OSS.</p> <p>Mike Pershin
