Attribute definition for CFSMount agent

Table: CFSMount Agent attributes lists user-modifiable attributes of the CFSMount Agent resource type.

Table: CFSMount Agent attributes

Attribute

Description

MountPoint

Directory for the mount point.

  • Type and dimension: string-scalar

BlockDevice

Block device for the mount point.

  • Type and dimension: string-scalar

NodeList

List of nodes on which to mount. If NodeList is NULL, the agent uses the service group system list.

  • Type and dimension: string-keylist

IMF

Resource-type level attribute that determines whether the CFSMount agent must perform intelligent resource monitoring. You can also override the value of this attribute at resource-level.

This attribute includes the following keys:

  • Mode: Define this attribute to enable or disable intelligent resource monitoring.

    Valid values are as follows:

    • 0 - Does not perform intelligent resource monitoring

    • 1 - Performs intelligent resource monitoring for offline resources and performs poll-based monitoring for online resources

    • 2 - Performs intelligent resource monitoring for online resources and performs poll-based monitoring for offline resources

    • 3 - Performs intelligent resource monitoring for both online and for offline resources

    Default: 0

  • MonitorFreq: This key value specifies the frequency at which the agent invokes the monitor agent function. The value of this key is an integer.

    Default: 1

    You can set this key to a non-zero value for cases where the agent requires to perform both poll-based and intelligent resource monitoring. If the value is 0, the agent does not perform poll-based process check monitoring.

    After the resource registers with the AMF kernel driver, the agent calls the monitor agent function as follows:

    • After every (MonitorFreq x MonitorInterval) number of seconds for online resources

    • After every (MonitorFreq x OfflineMonitorInterval) number of seconds for offline resources

  • RegisterRetryLimit: If you enable intelligent resource monitoring, the agent invokes the imf_register agent function to register the resource with the AMF kernel driver. The value of the RegisterRetyLimit key determines the number of times the agent must retry registration for a resource. If the agent cannot register the resource within the limit that is specified, then intelligent monitoring is disabled until the resource state changes or the value of the Mode key changes.

    Default: 3.

  • Type and dimension: integer-association

See Enabling and disabling intelligent resource monitoring for agents manually.

MountOpt

(optional)

Options for the mount command. To create a valid MountOpt attribute string:

  • Use the VxFS type-specific options only.

  • Do not use the -o flag to specify the VxFS-specific options.

  • Do not use the -t vxfs file system type option.

  • Be aware the cluster option is not required.

  • Specify options in comma-separated list:

     ro 
    ro,cluster 
    blkclear,mincache=closesync
  • Type and dimension: string-scalar

Policy (optional)

List of nodes to assume the primaryship of the cluster file system if the primary fails. If set to NULL or if none of the hosts specified in the list is active when the primary fails, a node is randomly selected from the set of active nodes to assume primaryship.

  • Type and dimension: string-scalar
