  8. A cluster filesystem.
  9. Allows a cluster of computers to simultaneously use a block device
  10. that is shared between them (with FC, iSCSI, NBD, etc...). GFS reads
  11. and writes to the block device like a local filesystem, but also uses
  12. a lock module to allow the computers coordinate their I/O so
  13. filesystem consistency is maintained. One of the nifty features of
  14. GFS is perfect consistency -- changes made to the filesystem on one
  15. machine show up immediately on all other machines in the cluster.
  16. To use the GFS2 filesystem in a cluster, you will need to enable
  17. the locking module below. Documentation and utilities for GFS2 can
  18. be found here: http://sources.redhat.com/cluster
  19. The "nolock" lock module is now built in to GFS2 by default. If
  20. you want to use the DLM, be sure to enable IPv4/6 networking.

  26. Multiple node locking module for GFS2
  27. Most users of GFS2 will require this. It provides the locking
  28. interface between GFS2 and the DLM, which is required to use GFS2
  29. in a cluster environment.
