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. In such cases, it may also be useful to run lfsck, a Lustre™-specific tool that checks the coherency of a running Lustre file system as a whole.

A Lustre-specific version of e2fsprogs can be found at http://downloads.lustre.org/public/tools/e2fsprogs/. A quilt patchset of all changes to the vanilla e2fsprogs is available in e2fsprogs-{version}-patches.tgz.

For information about e2fsck, see:

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