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.
