DRBD comes with a set of administration tools which communicate with the kernel module in order to configure and administer DRBD resources.
drbdadm
. The high-level administration tool of the DRBD program suite. Obtains all DRBD
configuration parameters from the configuration file /etc/drbd.conf
and acts
as a front-end for drbdsetup
and drbdmeta
. drbdadm
has a dry-run mode,
invoked with the -d
option, that shows which drbdsetup
and drbdmeta
calls
drbdadm
would issue without actually calling those commands.
drbdsetup
. Configures the DRBD module loaded into the kernel. All parameters to
drbdsetup
must be passed on the command line. The separation between
drbdadm
and drbdsetup
allows for maximum flexibility. Most users will
rarely need to use drbdsetup
directly, if at all.
drbdmeta
. Allows to create, dump, restore, and modify DRBD meta data structures. Like
drbdsetup
, most users will only rarely need to use drbdmeta
directly.
