Yuehui, If you intend to replicate one file system entirely and you want to use lustre tools, you might want to check out lustre_rsync as documented in the lustre wiki. Or, if the intend is to replicate data/files within a filesystem, lfs mirror as pointed out by Collin could be used.
Both documented here: Lustre* Software Release 2.x (whamcloud.com)<https://build.whamcloud.com/job/lustre-manual/lastSuccessfulBuild/artifact/lustre_manual.xhtml> Other than that, the usual suspects can be used, such as rsync or mpifileutils and so on.
