This should trigger a rebalance of the metadata. Obviously that's not a very good solution, so the question is whether a tuning parameter or the like could be added - or perhaps a new tool - that would rebalance files and directories in DNE.</p> LU-4029

The core DNE Phase 1 was landed in 2.4, <a href="https://jira.hpdd.intel.com/browse/LU-1187" class="external-link" target="_blank" rel="nofollow noopener">https://jira.hpdd.intel.com/browse/LU-1187</a>. </p> <p>Generally newer clients are supported with older servers but most features are in the Server. All Lustre servers should be of the same Lustre version.</p> <p>Am I misunderstanding your question?</p> Duplicate LU-4684 Development Rank 1|hzw4fj: Rank (Obsolete) 10825
