Name
hb_standby — issues a failover request to the cluster manager
Synopsis
hb_standby [all|foreign|local|failback]
Description
![[Warning]](images/warning.png) | Warning |
|---|---|
This command is deprecated. It is only suitable for legacy Heartbeat clusters without Pacemaker enabled. In Pacemaker-enabled clusters, the crm(8) shell supports switching individual nodes into standby mode, and replaces hb_standby. |
/usr/share/heartbeat/hb_standby issues a
request to the cluster to move resources from the node where it is
invoked, to the other node (if it is currently available). The
meaning of the options is relative. This manual assumes the
following configuration to be present in
/etc/ha.d/haresources:
alice drbddisk::r0 Filesystem::/dev/drbd0::/local/groups::ext3 10.0.0.1 smb bob drbddisk::r1 Filesystem::/dev/drbd1::/local/ldap::ext3 10.0.0.2 ldap
Options
The following options are supported:
- local
Migrates any resources that the local node is the preferred node for.
When invoked on
alice, Samba would be shut down, the IP address 10.0.0.1 would be released,/local/groupswould be unmounted,/dev/drbd0would be placed into the secondary role andbobwould take all these services over.When run on
bob, OpenLDAP would shut down, 10.0.0.2 would be released,/local/ldapwould be unmounted,/dev/drbd1would be placed into the Secondary role andalicewould take over all these services.- foreign|failback
Migrates any resources that the local node is not the preferred node for.
When run on
alice, OpenLDAP would shut down, 10.0.0.2 would be released,/local/ldapwould be unmounted,/dev/drbd1would be placed into the Secondary role andbobwould take over all these services.When invoked on
bob, Samba would be shut down, the IP address 10.0.0.1 would be released,/local/groupswould be unmounted,/dev/drbd0would be placed into the secondary role andalicewould take all these services over.- all
Migrates all resources to the other node.
Invoking hb_standby without any options is identical to hb_standby all.
