CCS(8)CCS(8)NAMEccs - Cluster Configuration System
SYNOPSISccs [-h hostname | -f filename] [options]
DESCRIPTIONccs allows an administrator to create, modify and view a cluster con‐
figuration file on a remote node through ricci or on a local file sys‐
tem. Using ccs an administrator can also start and stop the cluster
services on one or all of the nodes in a configured cluster.
OPTIONS
Generally all command lines must specify either a hostname or filename
to act upon.
MAIN OPTIONS
--help Display this help and exit
-h, --host host
Cluster node to perform actions on
-f, --file file
File to perform actions on
-i, --ignore
Ignore validation errors in cluster.conf file
-p, --password
Ricci user password for node running ricci
--getconf
Print current cluster.conf file
--setconf
Use the file specified by '-f' to send to the host specified
with '-h'
--checkconf
If file is specified, verify that all the nodes in the file have
the same cluster.conf as the file. If a host is specified then
verify that all nodes in the host's cluster.conf file have the
identical
--getschema
Print current cluster schema file (if using -h use schema from
network, if using -f use local schema)
--sync Sync config file to all nodes
--activate
Activate config on node (use this option with --sync to activate
config on all nodes)
-d, --debug
Display debugging information to help troubleshoot connection
issues with ricci
--exp tag [location] [options]
Expert mode to add elements not currently defined in ccs--exprm location
Expert mode to remove elements not currently defined in ccs
CLUSTER OPERATIONS
--createcluster cluster
Create a new cluster.conf (removing old one if it exists)
--getversion
Get the current cluster.conf version
--setversion <n>
Set the cluster.conf version
--incversion
Increment the cluster.conf version by 1
--startall
Start *AND* enable cluster services on reboot on all nodes
--stopall
Stop *AND* disable cluster services on reboot for all nodes
--start
Start *AND* enable cluster services on reboot for host specified
with -h
--stop Stop *AND* disable cluster services on reboot for host specified
with -h
NODE OPERATIONS
--lsnodes
List all nodes in the cluster
--addnode <node>
Add node <node> to the cluster
--rmnode <node>
Remove a node from the cluster
--nodeid <nodeid>
Specify nodeid when adding a node
--votes <votes>
Specify number of votes when adding a node
--addalt <node name> <alt name> [alt options]
Add an altname to a node for RRP
--rmalt <node name>
Remove an altname from a node for RRP
FENCING OPERATIONS
--lsfenceopts [fence type]
List available fence devices. If a fence type is specified,
then list options for the specified fence type
--lsfencedev
List all of the fence devices configured
--lsfenceinst [<node>]
List all of the fence methods and instances on the specified
node or all nodes if no node is specified
--addmethod <method> <node>
Add a fence method to a specific node
--rmmethod <method> <node>
Remove a fence method from a specific node
--addfencedev <device name> [fence device options]
Add fence device. Fence devices and parameters can be found in
online documentation in 'Fence Device Parameters'
--rmfencedev <fence device name>
Remove fence device
--addfenceinst <fence device name> <node> <method> [options] [--noun‐
fence]
Add fence instance. Fence instance parameters can be found in
online documentation in 'Fence Device Parameters'. Using
--nounfence prevents ccs from automatically including an unfenc‐
ing section for agents that require unfencing (ie. fence_scsi,
fence_sanlock, etc.)
--rmfenceinst <fence device name> <node> <method>
Remove all instances of the fence device listed from the given
method and node
--addunfenceinst <fence device name> <node> [options]
Add an unfence instance
--rmunfenceinst <fence device name> <node>
Remove all instances of the fence device listed from the unfence
section of the node
FAILOVER DOMAIN OPERATIONS
--lsfailoverdomain
Lists all of the failover domains and failover domain nodes con‐
figured in the cluster
--addfailoverdomain <name> [restricted] [ordered] [nofailback]
Add failover domain
--rmfailoverdomain <name>
Remove failover domain
--addfailoverdomainnode <failover domain> <node> [priority]
Add node to given failover domain
--rmfailoverdomainnode <failover domain> <node>
Remove node from failover domain
SERVICE OPERATIONS
--lsserviceopts [service type]
List available services. If a service type is specified, then
list options for the specified service type
--lsresourceopts [service type]
An alias to --lsserviceopts
--lsservices
List currently configured services and resources in the cluster
--addresource <resource type> [resource options] ...
Add global cluster resources to the cluster Resource types and
variables can be found in the online documentation under 'HA
Resource Parameters'
--rmresource <resource type> [resource options]
Remove specified resource with resource options
--addservice <servicename> [service options] ...
Add service to cluster
--rmservice <servicename>
Removes a service and all of its subservices
--addvm <virtual machine name> [vm options] ...
Adds a virtual machine to the cluster
--rmvm <virtual machine name>
Removes named virtual machine from the cluster
--addsubservice <servicename> <subservice> [service options] ...
Add individual subservices, if adding child services, use ':' to
separate parent and child subservices and brackets to identify
subservices of the same type
Subservice types and variables can be found in the online docu‐
mentation under 'HA Resource Parameters'
To add a nfsclient subservice as a child of the 2nd nfsclient
subservice in the 'service_a' service use the following example:
ccs <...> --addsubservice service_a nfsclient[1]:nfsclient
ref=/test
--rmsubservice <servicename> <subservice>
Removes a specific subservice specified by the subservice, using
':' to separate elements and brackets to identify between sub‐
services of the same type.
To remove the 1st nfsclient child subservice of the 2nd
nfsclient subservice in the 'service_a' service, use the follow‐
ing example:
ccs <...> --rmsubservice service_a nfsclient[1]:nfsclient
QUORUM OPERATIONS
--lsquorum
List quorum options and heuristics
--setquorumd [quorumd options] ...
Add quorumd options
--addheuristic [heuristic options] ...
Add heuristics to quorumd
--rmheuristic [heuristic options] ...

MISC OPTIONS
--lsmisc
List all of the misc options
--settotem [totem options]
Set totem options
--setdlm [dlm options]
Set dlm options
--setrm [resource manager options]

--setmulticast [multicast address] [multicast options]

address is given)
--setaltmulticast [alt multicast address] [alt multicast options]

multicast address is given)
--setfencedaemon [fence daemon options]
Set fence daemon options
--setlogging [logging options]
Set logging options
--addlogging [logging daemon options]
Add a logging daemon (see cluster.conf for options)
--rmlogging [logging daemon options]
Remove the logging daemon with the specified options
FILES
~/.ccs/cacert.config ~/.ccs/cacert.pem ~/.ccs/privkey.pem
Automatically generated certificate files used to authenticate
with ricci.
