drbdadm - Administration tool for DRBD
drbdadm [ -d ] [ -c file ] [ -s cmd ] command [ all | resource ... ]
Drbdadm is the high level tool of the DRBD program suite. Drbdadm is to
drbdsetup what ifup/ifdown is to ifconfig. Drbdadm reads its
configuration file and performs the specified commands by calling the
Just prints the calls of drbdsetup to stdout, but does not run
-c, --config-file file
Specifies the configuration file drbdadm will use. If this
parameter is not specified, drbdadm will look for
/etc/drbd-07.conf and /etc/drbd.conf.
-s, --drbdsetup file
Specifies the full path to the drbdsetup program. If this option
is omitted, drbdadm will look for /sbin/drbdsetup and
attach Attaches a local backing block device to the DRBD resource’s
device. In file system language this would be the mount
detach Removes the backing storage device from a DRBD resources’s
Sets up the network configuration of the resource’s device. If
the peer device is already configured, the two DRBD devices will
Removes the network configuration from the resource. The device
will go into StandAllone state.
syncer Loads the resynchronization parameters into the device.
up Is a shortcut for attach and connect.
down Is a shortcut for disconnect and detach.
Switch the resource’s device into primary state. You need to do
this before you may mount a filesystem onto the device.
Brings the device back into secondary state. This is needed
since in a connected DRBD device pair there might only be one of
the two peers in primary state.
This forces DRBD to consider the data on the local backing
storage device as out-of-sync. Therefor DRBD will copy each and
every block over from its peer, to bring the local storage
device back in sync.
This command is similar to the invalidate command, but the
backing storage of the peer is invalidated and hence rewritten
with the data of the local node.
resize DRBD will reexamine all sizing constraints, and re-size the
resource’s device accordingly. E.g. in case you increased the
size of your backing storage devices (on both nodes of course),
then DRBD will adopt to the new size after you called this
command on _both_ nodes.
adjust Synchronizes the configuration of device with your configuration
file. You should always examine the output of the dry-run mode
before actually executing this command.
Waits until the device is connected to its peer device.
state Shows the current states of the devices (local/peer). E.g.
cstate Shows the current connection status of the devices.
dump Just parse the configuration file and dump it to stdout. Might
be used to check the configuration file for syntactical
