Allow for lfs migrate between MDTs to include DOM

Improvement Minor Open Unresolved Lai Siyao Kyle Lamb Wed, 17 Jun 2020 17:18:54 +0000 Fri, 6 Jan 2023 20:10:28 +0000 0 6 <p>Mike, and Lai, could you please provide some input on how easy or hard this would be to implement.</p> <p>This is similar to DNE directory migration, but would also move the DoM data. I believe that it is possible to create FLR mirrors of DoM files today, but this keeps the same inode on the MDT. AFAIK, it is <b>not</b> possible to migrate the inode with DoM to a different MDT at the same time, but maybe that was implemented in 2.14?</p> <p>In the last patch of <a href="https://jira.whamcloud.com/browse/LU-11025" title="DNE3: directory restripe" class="issue-link" data-issue-key="LU-11025"><del>LU-11025</del></a>, if it's DoM file, migration will migrate dirent, and leave inode untouched, instead of return -EOPNOTSUPP.</p> Related LU-13298 LU-11025 Development Epic/Theme dne Rank 1|i0131b: Rank (Obsolete) 9223372036854775807
