Nobody is currently working on directory split. There are a number of other DNE optimizations that are underway (mostly internal code, locking, and recovery improvements without much "visible" to the outside world). The main feature in progress on the metadata side is the metadata writeback cache (WBC) that will greatly improve single-client workloads in a single directory tree (e.g. untar and then build/process files in that tree). That should help significantly with genomics and machine learning workloads that have this kind of usage pattern.

Re: [lustre-discuss] Configuring LustreFS Over DRBD
Hi Shambhu, I also think active-active is not possible here - two NIDs for the same target? - but we have been running our MDTs on top of DRBD, which works quite well. The last time I compared this setup against a mirror of storage targets, DRBD was actually a bit faster. And it might improve if you use protocol B or A instead of C.

Can I configure lustre file system over DRBD in redhat 8.7 ... If yes, how can it be configured ?
