| action | Overrides resource action timings for a resource instance. |
| altmulticast | The altmulticast element provides the ability for a user to specify a multicast address, port and TTL (Time To Live) instead of using cman defaults for the alternate communication channel (RRP). If a user does not specify an alternate multicast address, cman creates one. It forms the upper 16 bits of the multicast address with 239.192 for IPv4 and ff15:: for IPv6 and forms the lower 16 bits based on the cluster ID + 1. |
| altname | Defines a second network interface to use for corosync redundant ring mode. cman(5) |

| fence_xvmd | Fence_xvm daemon. The fence_xvmd fence device is an I/O fencing host that resides on dom0 and is used in conjunction with the fence_xvm fencing agent. Together, these two programs fence Xen virtual machines that are in a cluster. There is a requirement that the parent dom0s are also a part of their own CMAN/OpenAIS based cluster, and that the dom0 cluster does not share any members with the domU cluster. Furthermore, the dom0 cluster is required to have fencing if domU recovery is expected to be automatic. |
| fs | Defines a file system mount. |

| resources | Defines global resources which may be referenced in services. You may redefine actions for resources here, but child resource definitions are ignored in this section. |
| resource-defaults | This section allows the administrator to change defaults for resource agents. Overriding parameters which must be unique is not allowed. Overriding a value which, by default, inherits a value from a parent resource will disable inheritance for that resource type. |

| Attribute | Description |
| broadcast | enable cman broadcast |
| ccsd_poll | |
| cluster_id | |
| debug_mask | |
| disable_openais | |
| disallowed | Set this to 1 enable cman's Disallowed mode. This is usually only needed for backwards compatibility. |
| expected_votes | The expected votes value is used by cman to determine quorum. The cluster is quorate if the sum of votes of members is over half of the expected votes value. By default, cman sets the expected votes value to be the sum of votes of all nodes listed in cluster.conf. This can be overriden by setting an explicit expected_votes value. |
| hash_cluster_id | Enable stronger hashing of cluster ID to avoid collisions. |
| keyfile | |
| nodename | Local node name; this is set internally by cman-preconfig and should never be set by a user. |

The quorum disk daemon, qdisk, periodically sends hello messages to cman and ais, indicating that qdisk is present. If qdisk takes more time to send a hello message to cman and ais than by quorum_dev_poll, then cman declares qdisk dead and prints a message indicating that connection to the quorum device has been lost. |
| shutdown_timeout | Timeout period, in milliseconds, to allow a service to respond during a shutdown. |
| transport | Specifies transport mechanism to use. Available values are udp (multicast default), udpb (broadcast), udpu (unicast) and rdma (Infiniband). corosync.conf(5) |
| two_node | The two_node attribute allows you to configure a cluster with only two nodes. Ordinarily, the loss of quorum after one of two nodes fails prevents the remaining node from continuing (if both nodes have one vote.) To enable a two-node cluster, set the two_node value equal to 1. If the two_node value is enabled, the expected_votes value must be set to 1. |
| upgrading | Set this if you are performing a rolling upgrade of the cluster between major releases. |

| Attribute | Description |
| consensus | This is a timeout value that specifies how many milliseconds to wait for consensus to be achieved before starting a new round of membership configuration. |
| fail_recv_const | |
| join | This is a timeout value that specifies how many milliseconds to wait for join messages in the membership protocol. |
| keyfile | |
| max_messages | Specifies the maximum number of messages that may be sent by one processor on receipt of the token. This parameter is limited to 256000 / netmtu to prevent overflow of the kernel transmit buffers |
| miss_count_const | This constant defines the maximum number of times on receipt of a token a message is checked for retransmission before retransmission occurs. This parameter is useful to modify for switches that delay multicast packets compared to unicast packets. The default setting works well for nearly all modern switches. |
| netmtu | Specifies the network maximum transmit unit. To set this value beyond 1500, the regular frame MTU, requires ethernet devices that support large, or also called jumbo, frames. If any device in the network does not support large frames, the protocol will not operate properly. The hosts must also have their mtu size set from 1500 to whatever frame size is specified here. |
| rrp_mode | This attribute specifies the redundant ring protocol mode. Its value can be set to active, passive, or none. Active replication offers slightly lower latency from transmit to delivery in faulty network environments but with less performance. Passive replication may nearly double the speed of the totem protocol if the protocol doesn't become cpu bound. The final option is none, in which case only one network interface is used to operate the totem protocol. If only one interface directive is specified, none is automatically chosen. If multiple interface directives are specified, only active or passive may be chosen. |
| rrp_problem_count_threshold | This specifies the number of times a problem is detected with a link before setting the link faulty. Once a link is set faulty, no more data is transmitted upon it. Corosync default is 10, cman default is 3 |
| secauth | This attribute specifies that HMAC/SHA1 authentication should be used to authenticate all messages. It further specifies that all data should be encrypted with the sober128 encryption algorithm to protect data from eavesdropping. For more information setting this value, refer the the openais.conf man page. |
| seqno_unchanged_const | Specifies how many rotations of the token without any multicast traffic should occur before the merge detection timeout is started. |
| token | This is a timeout value that specifies how many milliseconds elapse before a token loss is declared after not receiving a token. This is the time spent detecting a failure of a processor in the current configuration. Reforming a new configuration takes about 50 milliseconds in addition to this timeout. |
| token_retransmits_before_loss_const | This value identifies how many token retransmits should be attempted before forming a new configuration. If this value is set, retransmit and hold will be automatically calculated from retransmits_before_loss and token. |
| window_size | Specifies the maximum number of messages that may be sent on one token rotation. window_size should be no larger then 256000 / netmtu to avoid overflow of the kernel receive buffers. |
| Attribute | Description |
| autostart | Automatic start after quorum formation |
| depend | Top-level service this depends on, in service:name format. |
| depend_mode | Service dependency mode (soft or hard). |
| domain | Cluster failover Domain |
| exclusive | Exclusive resource group |
| hypervisor | Hypervisor |
| hypervisor_uri | Hypervisor URI (normally automatic). |
| max_restarts | Maximum restarts for this service. |
| migrate | Migration type (live or pause, default = live). |
| migration_mapping | memberhost:targethost,memberhost:targethost .. |
| migration_uri | Migration URI (normally automatic). |
| name | Name |
| path | Path to virtual machine configuration files. |
| recovery | Failure recovery policy |
| ref | Reference to existing vm resource in the resources section. |
| restart_expire_time | Restart expiration time; amount of time before a restart is forgotten. |
| snapshot | Path to the snapshot directory where the virtual machine image will be stored. |
| status_program | Additional status check program |
| tunnelled | Tunnel data over ssh to securely migrate virtual machines. |
| use_virsh | If set to 1, vm.sh will use the virsh command to manage virtual machines instead of xm. This is required when using non-Xen virtual machines (e.g. qemu / KVM). |
| xmlfile | Full path to libvirt XML file describing the domain. |
| __enforce_timeouts | Consider a timeout for operations as fatal. |
| __failure_expire_time | Amount of time before a failure is forgotten. |
| __independent_subtree | Treat this and all children as an independent subtree. |
| __max_failures | Maximum number of failures before returning a failure to a status check. |
| __max_restarts | Maximum number restarts for an independent subtree before giving up. |
| __restart_expire_time | Amount of time before a failure is forgotten for an independent subtree. |
