config GFS2_FS tristate "GFS2 file system support" select FS_POSIX_ACL select CRC32 select LIBCRC32C select QUOTACTL select FS_IOMAP help A cluster filesystem.

  Allows a cluster of computers to simultaneously use a block device
  that is shared between them (with FC, iSCSI, NBD, etc...).  GFS reads
  and writes to the block device like a local filesystem, but also uses
  a lock module to allow the computers coordinate their I/O so
  filesystem consistency is maintained.  One of the nifty features of
  GFS is perfect consistency -- changes made to the filesystem on one
  machine show up immediately on all other machines in the cluster.

  To use the GFS2 filesystem in a cluster, you will need to enable
  the locking module below. Documentation and utilities for GFS2 can
  be found here: http://sources.redhat.com/cluster

  The "nolock" lock module is now built in to GFS2 by default. If
  you want to use the DLM, be sure to enable IPv4/6 networking.

config GFS2_FS_LOCKING_DLM bool "GFS2 DLM locking" depends on (GFS2_FS!=n) && NET && INET && (IPV6 || IPV6=n) &&
CONFIGFS_FS && SYSFS && (DLM=y || DLM=GFS2_FS) help Multiple node locking module for GFS2

  Most users of GFS2 will require this. It provides the locking
  interface between GFS2 and the DLM, which is required to use GFS2
  in a cluster environment.
