clusvcadm(8) Red Hat Cluster Suite clusvcadm(8)NAMEclusvcadm - Cluster User Service Administration Utility
SYNOPSISclusvcadm [-d <service> ] [-e <service> [-F] ] [-l] [-u] [-S] [-m <mem‐
ber> ] [-r <service> ] [-R <service> ] [-M <service> ] [-Z <service> ]
[-U <service> ] [-s <service> ] [-c <service> ] [-v]
DESCRIPTION
The clusvcadm command allows an administrator to enable, disable, relo‐
cate, and restart user services in a cluster. In order to perform
cluster service operations, the cluster daemons must be running (and
have quorum) on the member system on which the command is invoked.
OPTIONS-d <service>
Stops and disables the user service named service
-e <service> [-F]
Enables and starts the user service named service
Normally, rgmanager starts the service locally (i.e. on the host
where clusvcadm was run). However, if the -F option is speci‐
fied, rgmanager will use the assigned failover domain rules as
hints on where to start the service.
-l Lock services in preparation for cluster shutdown. This should
only be used if the administrator intends to perform a global,
cluster wide shutdown. This prevents services from starting
(but not stopping, like -Z does). Once the cluster quorum is
dissolved, this state is reset. If a new instance of rgmanager
boots while others are locked, the behavior is undefined.
-u Unlock resource group managers. This allows services to start
again.
-S Display whether the resource group managers are locked or not.
This can be used to verify the correct operation of the -l and
-u options, but is only useful for debugging.
-m <member>
When used in conjunction with either the -e or -r options, this
specifies the preferred target member on which to start the ser‐
vice.
-r <service>
Relocates the user service named service to another cluster mem‐
ber.
-R <service>
Restarts the user service named service on the cluster member on
which it is currently running.
-M <service>
Use a special "migration" operation to move the user service
named service to another cluster member. Currently, this is
only useful for virtual machines. Use of migration usually
requires special configuration of the local virtual machine man‐
ager in order to work correctly.
-Z <service>
Freezes the service named service on the cluster member on which
it is currently running. This will prevent status checks of the
service as well as failover in the event the node fails or
rgmanager is stopped.
-U <service>
Unfreezes the user service named service on the cluster member
on which it is currently running. This will re-enable status
checks.
-s <service>
Stops the service named service until a member transition or
until it is enabled again.
-c <service>
Attempt to convalesce the named service by restarting failed,
non-critical components.
-v Display version information and exit.
NOTES
Executing -U (unfreeze) on a service which was frozen in the started
state while the service owner is offline results in an undefined (and
possibly dangerous) condition. Manually ensure all resources are clear
before doing this.
