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

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