The client knowns what version of the servers it is connected to.</p> <p>It would be good to expose the server version on the client. A starting point for this information would be <tt>struct obd_connect_data:ocd_version</tt></p> LU-2814

Bug Minor Resolved Fixed WC Triage Richard Henwood hackathon2017 Thu, 14 Feb 2013 11:14:18 +0000 Wed, 7 Jun 2017 19:38:54 +0000 Tue, 30 May 2017 17:39:55 +0000 Lustre 2.6.0 0 4 <p>One option is to have /proc/fs/lustre/</p> {osc,mdc} <p>/*/import also print out the data fields in obd_connect_data, in addition to just the flags. This would be useful for a number of reasons, in addition to just getting the server versions. I was just thinking that it would be good for getting the ocd_brw_size during 4MB patch testing, etc. Something like:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>import: name: myth-OST0000-osc-ffff88004fc2d800 target: myth-OST0000_UUID state: FULL connect_flags: [write_grant, server_lock, version, request_portal, truncate_lock, max_byte_per_rpc, early_lock_cancel, adaptive_timeouts, lru_resize, alt_checksum_algorithm, version_recovery, full20, 64bithash, object_max_bytes] connect_data: version: 2.1.3 grant: 2097152 index: 0 brw_size: 4194304 ibits_known: 0xf blocksize: 4096 inodespace: 0 grant_extent: 24 transno: 0 group: 0 cksum_types: [ crc32, adler, crc32c ] max_easize: 4048 instance: 4 maxbytes: 17179869184 </pre> </div></div> <p>Note that the "instance:" field should be moved into the "connect_data" section rather than being a separate field.</p> <p>Was just about to suggest the same thing. <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/></p> <p>This was fixed with patch <a href="http://review.whamcloud.com/6588" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/6588</a> "<a href="https://jira.whamcloud.com/browse/LU-3386" title="improve osc/mdc &quot;imports&quot; connect data" class="issue-link" data-issue-key="LU-3386"><del>LU-3386</del></a> lproc: improve osc/mdc "imports" connect data" which was landed to master in commit v2_5_52_0-67-g62660c7.</p> Related LU-3386 Development Rank 1|hzvj5r: Rank (Obsolete) 6818 Severity
