Hello Fernando, The option is enabled by command:
tune2fs -O large_dir <ldiskfs_partition> BUT, this feature is still in testing, so I do not suggest use it in production. Also, current Lustre FS e2fsprogs don’t support this feature. Now it available only for EXT4 since E2fsprogs 1.44.0 (March 7, 2018) and linux 4.13. I hope this feature will be enabled in WC e2fsprogs which will be released with Lustre FS 2.12.
