What about using “lfs df -i” to get the inode count for each OST? It wouldn’t be exact since there are some inodes that don’t correspond to file objects, but if there are large numbers of files on an OST, it might be reasonably close. (I guess it depends on just how accurate you need the number to be.) -- Rick Mohr Senior HPC System Administrator National Institute for Computational Sciences http://www.nics.tennessee.edu _______________________________________________ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
