...ems, is there any reason not to create each one with its own combined MGS/MDT? 2. Can an MGS which is a combined MGS/MDT for one file system serve as the MGS for one or more other file systems where the MGS and MDT are separate? 3. Is there any reason why doing several separate combined MGS/MDTs (one for each file system) won''t work? What are other sites w/ multiple Lustre file systems doing? A dedicated MGS seems like a costly option. Thanks, Charlie Taylor UF HPC Center

In 1.6.0, when creating a MDT, you could specify multiple --mgsnode options and it would failover between them. 1.6.3 only seems to take the last one and --mgsnode=192.168.1.252 at o2ib:192.168.1.253 at o2ib doesn''t seem to failover to the other node. Any ideas how to get around this? Robert Robert LeBlanc College of Life Sciences Computer Support Brigham Young University leblanc at

We have been struggling with our Lustre performance for some time now especially with large directories. I recently did some informal benchmarking (on a live system so I know results are not scientifically valid) and noticed a huge drop in performance of reads(stat operations) past 20k files in a single directory. I''m using bonnie++, disabling IO testing (-s 0) and just creating, reading,
