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 filesystem as a whole.
For information on the following topics, see Fsck Support.

- Using e2fsck on a backing filesystem
- Running e2fsck+lfsck on a corrupted Lustre filesystem
