Fix race during new fsdb creation.

Bug Major Resolved Fixed Keith Mannthey Andriy Skulysh patch Sat, 3 Mar 2012 11:49:04 +0000 Tue, 27 Nov 2012 18:19:11 +0000 Tue, 27 Nov 2012 18:19:11 +0000 Lustre 2.4.0 0 2 <p>CODE: <a href="http://review.whamcloud.com/2251" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/2251</a></p> <p>Andriy,<br/> I haven't looked at the patch yet, and it is definitely good to fix such a problem like this. Note however that the use of MGS-assigned OST index values is deprecated, and will be removed entirely in the future. All of the customers we talked to already specify "--index=N" when formatting their filesystems today.</p> <p>The reason is that outside of test environments, customers care about specific OST-&gt;disk assignments for maintenance reasons (i.e. to locate specific disks when an OST reports errors), so random MGS-assigned OST index values are not useful. Requiring that the user (or management interface) specify the OST index at format time avoids any confusion or misordering between OST and LUN/OSS layouts.</p> <p>The patch fixes race between loading data from llog into fsdb and obtaining data form it. It doesn't matter if a index was specified manually or automatically assigned.<br/> I suppose the races should be fixed until fsdb code removal. </p> <p>Integrated in <span class="image-wrap" style=""><img src="http://iu-build.whamcloud.com/images/16x16/blue.png" style="border: 0px solid black" /></span> <a href="http://iu-build.whamcloud.com/job/lustre-reviews/./arch=x86_64,build_type=client,distro=el6,ib_stack=inkernel/4629/" class="external-link" target="_blank" rel="nofollow noopener">lustre-reviews » x86_64,client,el6,inkernel #4629</a><br/> <a href="https://jira.whamcloud.com/browse/LU-1169" title="Fix race during new fsdb creation." class="issue-link" data-issue-key="LU-1169"><del>LU-1169</del></a> mgs: Fix race during new fsdb creation.
