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.
- Where to get e2fsck support for Lustre
- Code for e2fsprogs-lustre
- Using e2fsck on a backing filesystem
- How to run e2fsck+lfsck on a corrupted Lustre filesystem
For more information about lfsck, see Chapter 28 in the Lustre Operations Manual.
