## Appendix C. HA Resource Parameters

This appendix provides descriptions of HA resource parameters. You can configure the parameters with Luci, `system-config-cluster`, or by editing `etc/cluster/cluster.conf`. Table C.1, “HA Resource Summary” lists the resources, their corresponding resource agents, and references to other tables containing parameter descriptions. To understand resource agents in more detail you can view them in `/usr/share/cluster` of any cluster node.

Resource | Resource Agent | Reference to Parameter Description
--- | --- | ---
Apache | apache.sh | Table C.2, “Apache Server”
File System | fs.sh | Table C.3, “File System”
GFS File System | clusterfs.sh | Table C.4, “GFS”
IP Address | ip.sh | Table C.5, “IP Address”
LVM | lvm.sh | Table C.6, “LVM”
MySQL | mysql.sh | Table C.7, “MySQL®”
NFS Client | nfsclient.sh | Table C.8, “NFS Client”
NFS Export | nfsexport.sh | Table C.9, “NFS Export”
NFS Mount | netfs.sh | Table C.10, “NFS Mount”
Open LDAP | openldap.sh | Table C.11, “Open LDAP”
Oracle 10g | oracledb.sh | Table C.12, “Oracle® 10g”
PostgreSQL 8 | postgres-8.sh | Table C.13, “PostgreSQL 8”
SAP Database | SAPDatabase | Table C.14, “SAP® Database”
SAP Instance | SAPInstance | Table C.15, “SAP® Instance”
Samba | smb.sh | Table C.16, “Samba Service”
Script | script.sh | Table C.17, “Script”
Service | service.sh | Table C.18, “Service”
Sybase ASE | ASEHAagent.sh | Table C.19, “Sybase® ASE Failover Instance”
Tomcat 5 | tomcat-5.sh | Table C.20, “Tomcat 5”
Virtual Machine | vm.sh | Table C.21, “Virtual Machine” NOTE: Luci displays this as a virtual service if the host cluster can support virtual machines.

###### Table C.1. HA Resource Summary

Field | cluster.conf | Description
--- | --- | ---
Name | name | The name of the Apache Service.
Server Root | server_root | The default value is `/etc/httpd`.
Config File | config_file | Specifies the Apache configuration file. The default valuer is `/etc/httpd/conf`.
httpd Options | httpd_options | Other command line options for `httpd`.
Shutdown Wait (seconds) | shutdown_wait | Specifies the number of seconds to wait for correct end of service shutdown.

###### Table C.2. Apache Server

Field | cluster.conf | Description
--- | --- | ---
Name | name | Specifies a name for the file system resource.
File System Type | fstype | If not specified, `mount` tries to determine the file system type.
Mount Point | mountpoint | Path in file system hierarchy to mount this file system.
Device | device | Specifies the device associated with the file system resource. This can be a block device, file system label, or UUID of a file system.
Options | options | Mount options; that is, options used when the file system is mounted. These may be file-system specific. Refer to the `mount`(8) man page for supported mount options.
File System ID | fsid | ## Note `File System ID` is used only by NFS services. When creating a new file system resource, you can leave this field blank. Leaving the field blank causes a file system ID to be assigned automatically after you commit the parameter during configuration. If you need to assign a file system ID explicitly, specify it in this field.
Force unmount | force_unmount | If enabled, forces the file system to unmount. The default setting is `disabled`. `Force Unmount` kills all processes using the mount point to free up the mount when it tries to unmount.
Reboot host node if unmount fails | self_fence | If enabled, reboots the node if unmounting this file system fails. The default setting is `disabled`.
Check file system before mounting | force_fsck | If enabled, causes `fsck` to be run on the file system before mounting it. The default setting is `disabled`.
