I have looked the paper "CHIRAYU: A Highly Available Metadata Server for Object Based Storage Cluster File System " from "www.cs.utexas.edu/ ~abhinay/research_papers/chirayu.pdf ". It tells how to backup MDS. But Lustre manual not metion how to configure it. Why? Thank you!

Why?The Lustre Operations Manual most certainly does talk about configuring MDS failover, in section "8. Failover" at http://manual.lustre.org/manual/LustreManual16_HTML/Failover.html#50446391_pgfId-5529 specifically at http://manual.lustre.org/manual/LustreManual16_HTML/Failover.html#50446391_pgfId-1287648 for MDS failover.
