DRBD
See the Configuring LifeKeeper section of the DRBD Recovery Kit Administration Guide for more information.
create drbd
Option | Default | Description |
---|---|---|
--device <str> | Source disk or partition. | |
--fstype <str> | File system type. Only the file system types supported by LifeKeeper can be specified. |
|
--mount_point <str> | New mount point for new file system. Mount point can not be mounted and must be empty. | |
[--fstag <str>] | mount_point | Tag name of the file system resource. Optional. |
extend drbd
Option | Default | Description |
---|---|---|
--device <str> | Target disk or partition that is the same size or larger than the source disk. | |
--mode <str> | Replication type: “asynchronous”, “memory synchronous”, “synchronous” | |
--laddr <str> | Local IP address (*1) | |
--raddr <str> | Remote IP address. | |
[--fstag <str>] | Tag name of the file system resource. Optional. Only the DRBD resource will be extended if not provided. | |
[--other_hosts …] | Required when extending > 2 targets. |
EXAMPLE: #lkcli resource extend drbd --tag <tag> --dest <target hostname> --mode <asynchronous|”memory synchronous”|asynchronous> --laddr <local IP address> --raddr <remote IP address> --switchback <switchback type> --template_prioity <priority> --target_priority <prority> --device <target disk> --fstag <target fs tag>
(*1) Local and Remote IP addresses must be configured as a LifeKeeper communication path.
When extending to a 3rd node the connection between each host in the configuration must be defined.
Option | Description |
---|---|
--other_hosts "<other sys>,<endpoints>,<mode>" | <other sys> is the host name of another target in the LifeKeeper resource. <endpoints> is a communication path between the new target host and <other sys> <mode> is asynchronous, “memory synchronous” or synchronous |
EXAMPLE: In a configuration where DRBD resource “drbd-lk0” is configured on 2 systems, system_A (12.0.0.1) and system_B (12.0.0.2). The hierarchy is in-service on system_A and is being extended to system_C (12.0.0.3) where replication between System_A and System_C will be “memory synchronization” and replication between System_B and System_C will be “asynchronous”.
#lkcli resource extend drbd --tag drbd-lk0 --dest system_C --mode “memory synchronous” --laddr 12.0.0.1 --raddr 12.0.0.3 --switchback INTELLIGENT --template_prioity 1 --target_priority 20 --device /dev/sdc1 --fstag /test_lk0 –other_hosts "system_B,12.0.0.3/12.0.0.2,asychronous"

No options. Use ‘lkcli drbd options’ to modify throttle settings.
