As you mentioned, LVM will work with Lustre. I believe this recommendation was originally intended for performance reasons. (i.e. - If the underlying storage was using RAID, then creating partitions might cause data not to align well with the RAID stripes.) But I could be wrong about that. -- Rick Mohr Senior HPC System Administrator National Institute for Computational Sciences http://www.nics.tennessee.edu _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
