From time to time, usually due to catastrophic disk / RAID failures, it may be necessary to repair the backing file system of an OST or MDT to correct file system errors. This is done using a special version of the e2fsck tool. It may also be useful to run lfsck in such cases. This is a Lustre™-specific tool that checks the coherency of a running Lustre file system as a whole.

For information on the following topics, see Fsck Support.

  • Obtaining e2fsck support for Lustre
  • Using e2fsck on a backing file system 19.5
  • Running e2fsck+lfsck on a corrupted Lustre file system

For more information about lfsck, see Section 27.2: lfsck in the Lustre Operations Manual.
