add lazyinit progress support

New Feature Minor Reopened Unresolved WC Triage Wang Shilong ldiskfs patch Mon, 16 May 2016 06:57:42 +0000 Mon, 13 Sep 2021 12:57:54 +0000 0 3 <p>Wang Shilong (wshilong@ddn.com) uploaded a new patch: <a href="http://review.whamcloud.com/20217" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/20217</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-8144" title="add lazyinit progress support" class="issue-link" data-issue-key="LU-8144">LU-8144</a> ldiskfs: add lazyinit stats support<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: a8cf3e8fd1ba8b5e80845b05c797793298f9fec1</p> <p>New features like this should really be sent upstream, so that we don't need to keep them in ldiskfs forever. I don't mind keeping ldiskfs patches for code that is in upstream, or if it is Lustre specific, but generic improvements like this would be better if they went into the mainline kernel.</p> <p>Upstream community think it unnecessary to add this support, so please close this ticket.</p> <p>I didn't get the impression that the upstream developers didn't want this. There was some discussion about whether it was useful, but even though it wasn't useful for their single-disk benchmarking, it would be useful for your large configurations.</p> <p>I think the main request was to change the interface to only one plain value per entry in sysfs, rather than having multiple values in a single entry. That means two separate entries - <tt>nr_block_groups</tt> and <tt>lazyinit_groups_done</tt> that only contain a single number each. The other suggestion was to change what the "total" value contained. The patch should be changed to report the total block group count in nr_block_groups and count any previously init groups in lazyinit_groups_done.</p> <p>Could you resubmit your patch upstream with these changes and see what the response is?</p> <p>Andreas, I will do that!</p> <p>Thanks<br/> Shilong</p> Related LU-13533 Development End date Fri, 27 May 2016 06:57:42 +0000 Rank 1|hzybov: Rank (Obsolete) 9223372036854775807 Start date Mon, 16 May 2016 06:57:42 +0000
