Also, does Lustre use large_dir on the MDS server, or on the Lustre
data server? Because I noticed that on the MDS server you're
apparently not using extents:
export EXT_MKFS_OPTIONS="-I 2048 -O ^64bit,mmp,uninit_bg,^extents,dir_nlink,...
^^^^^^^^
Are you really using large_dir on a file system that is using indirect
block mapped files?
