See the Recovering a Primary Node that Lost Quorum section of the DRBD User’s Guide for moreĭetails. Specifies whether or not to demote the node to a secondary role using `drbdadm’s force ![]() The resource was configured to suspend I/O operations upon loss of quorum, this setting If a node loses quorum, DRBD Reactor will try to demote the node to a secondary role. ActionsĬan be one of: reboot, reboot-force, reboot-immediate, poweroff, poweroff-force, That will trigger some “self-fencing” of the node and cause another node to promote. In such a case, an action should be taken on the node that fails to demote Specifies the action to take if a DRBD resource fails to demote, for example, after a loss This example, the promoter plug-in would start a file system mount unit and a service unit. Start specifies what should be started when the watched DRBD resource is promotable. Specifies the systemd dependency type to generate service dependencies in the final target Specifies the systemd dependency type to generate inter-service dependencies as. Promoter plug-in should watch and manage. ![]() “my_drbd_resource” specifies the name of the DRBD resource that DRBD Reactor and the When installed, this pulls in all other userland packages as dependencies.Įnables udev to manage user-friendly symlinks to DRBD devicesĮnables xend to auto-manage DRBD resourcesĮnables DRBD management by legacy v1-style Heartbeat clustersĮnables DRBD management by Pacemaker clustersĭRBD RedHat Cluster Suite integration scriptsĮnables DRBD management by rgmanager, the Red Hat Cluster Suite resource managerĮnables Programmable bash completion for the drbdadm utility The make rpm approach generates a number of RPM packages: Table 2.

Type of init script to install (sysv, systemd, or both).Ĭreate a distribution specific RPM spec fileįor package builders only: you may use this option if you want to create an RPM spec file adapted to your distribution. You may disable this option if you are using a shell other than bash, or if you do not want to utilize programmable completion for the drbdadm command. Installs a bash completion script for drbdadm You may disable this option if you don’t need the block-drbd helper script for Xen integration. Please note that you will need to pass -with rgmanager to rpmbuild to actually get the rgmanager-package built. You should enable this option if you are planning to use DRBD with rgmanager, the Red Hat Cluster Suite cluster resource manager. You may disable this option if you are not planning to use the Pacemaker cluster resource manager.īuild DRBD Red Hat Cluster Suite integration You may disable this option unless you are planning to use DRBD’s Heartbeat v1 resource agent or dopd.
