Ever since commit 45f035ab9b ("CONFIG_HOTPLUG should be always on"),
it has been basically impossible to build a kernel with CONFIG_HOTPLUG
turned off. Remove all the remaining references to it.

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.

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.
