https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-397 Lustre <p>The commit 06a67987e06f7fa9c0bfde549d54e2bed0a78ade introduced server identifier into lu_seq_range to distinguish between MDT and OST fids. But for old 2.0 client, it did not specify such identifier/flags, then caused 'fld_server_lookup()' failure.</p> LU-397

lustre 2.0 client can not mount to lustre 2.1 server

Bug Minor Resolved Fixed nasf nasf Mon, 6 Jun 2011 23:06:44 +0000 Tue, 14 Jun 2011 08:15:24 +0000 Mon, 13 Jun 2011 21:05:35 +0000 Lustre 2.0.0 Lustre 2.1.0 0 3 <p>I can't understand how this change could have affected the network protocol. It renamed the "lsr_mdt" field to "lsr_index", and "lsr_padding" to "lsr_flags", and replaced a constant "0" with LU_SEQ_RANGE_MDT, which is defined as 0 itself.</p> <p>It should be, but the parameter of "res" for 'fld_server_lookup()' is allocated on stack, some fields, including "lsr_padding/lsr_flags" is not initialized, so the value of "lsr_flags" may be not zero.</p> <p>The patch to be inspected:</p> <p><a href="http://review.whamcloud.com/#change,902" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,902</a></p> <p>Integrated in <span
