hb_standby — issues a failover request to the cluster manager
hb_standby [all|foreign|local|failback]
![]() | 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
The following options are supported:
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/groups
would be unmounted,
/dev/drbd0
would be placed into the
secondary role and bob
would take all these
services over.
When run on bob
, OpenLDAP would shut
down, 10.0.0.2 would be released,
/local/ldap
would be unmounted,
/dev/drbd1
would be placed into the
Secondary role and alice
would take over all
these services.
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/ldap
would be unmounted,
/dev/drbd1
would be placed into the
Secondary role and bob
would 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/groups
would be unmounted,
/dev/drbd0
would be placed into the
secondary role and alice
would take all these
services over.
Migrates all resources to the other node.
Invoking hb_standby without any options is identical to hb_standby all.
