OI Scrub project provides ground work for a complete Lustre FSCK tool. Crucial to success of this tool is performance. OI Scrub has been demonstrated checking over 100K files/second on a typical MDS hardware node. In addition, OI Scrub provides a on-line mode that has been shown to add negligible system load with limited scan rates:
