The Lustre File System Checker is a tool for verifying and repairing both the internal consistency of Lustre MDTs and OSTs, as well as the MDT-OST and MDT-MDT cross references. The LFSCK tool is run while the filesystem is mounted, and does not require that the filesystem is idle during checking or repair.
The LFSCK functionality was implemented in several phases:
- LFSCK 1 - Object Index Scrub for internal MDT/OST consistency checking and repair
- LFSCK 1.5 - FID-in-dirent/LinkEA checking and repair
- LFSCK 2 - MDT-OST file layout consistency checking and repair
- LFSCK 3 - MDT-MDT DNE remote and striped directory checking and repair
- LFSCK 4 - LFSCK performance enhancement
