drbd-kernel (Kernel Module for Distributed Replicated Block Device)
DRBD is a block device which is designed to build high availability
clusters. This is done by mirroring a whole block device via
(a dedicated) network. You could see it as a network RAID1. DRBD
takes over the data, writes it to the local disk and sends it to
the other host. On the other host, it takes it to the disk there.
Starting with Linux 2.6.33, DRBD is officially integrated into the
vanilla Linux kernel source. Besides the kernel integration, DRBD
continues to be developed out of tree.
If you have a 2.6.33 kernel, you should use the DRBD module shipped
with your kernel, or compile it from your kernel sources if it is
not available in your current configuration.
If you have an earlier kernel version then DRBD can be built as a
module, or it can be patched into the kernel. This build creates a
kernel module based on your current kernel using
/lib/modules/$(uname -r)/build as the kernel source tree. This may
not be appropriate for you and you may need to edit either the
KERNEL (uname -r) or KERNELPATH (/lib/modules/2.6.x-foo/build)
environment variable to point to the correct source or headers.
