ESMF ratio of data blocks to inodes the existing GFS partitions, including the /home backups

1031.843 512 byte blocks / inode


1032 is ~516K/inode Now to find out how many files can fit in 30TB: 30 * 1024 * 1024 * 1024 / 516 (K) = 62426850 files we would need With that many files, use the upper bound of 8k/file for Lustre 62426850 * 8 / 1024 / 1024 = ~476GB MDS filesystem. So in short, we should be safe with ~500GB of MDS filestorage if your file size distribution stays the same for a 30TB filesystem. I hope that math and data helps, Nic
