  7. A cluster filesystem.
  8. Allows a cluster of computers to simultaneously use a block device
  9. that is shared between them (with FC, iSCSI, NBD, etc...). GFS reads
  10. and writes to the block device like a local filesystem, but also uses
  11. a lock module to allow the computers coordinate their I/O so
  12. filesystem consistency is maintained. One of the nifty features of
  13. GFS is perfect consistency -- changes made to the filesystem on one
  14. machine show up immediately on all other machines in the cluster.
  15. To use the GFS2 filesystem, you will need to enable one or more of
  16. the below locking modules. Documentation and utilities for GFS2 can
  17. be found here: http://sources.redhat.com/cluster

  22. Single node locking module for GFS2.
  23. Use this module if you want to use GFS2 on a single node without
  24. its clustering features. You can still take advantage of the
  25. large file support, and upgrade to running a full cluster later on
  26. if required.
  27. If you will only be using GFS2 in cluster mode, you do not need this
  28. module.

  36. Multiple node locking module for GFS2
  37. Most users of GFS2 will require this module. It provides the locking
  38. interface between GFS2 and the DLM, which is required to use GFS2
  39. in a cluster environment.
