Property descriptions for the RSFCDB database

This is the list of supported properties in the cluster configuration database.
It can be displayed running the following command: "rsfcdb -I list_props"

prop_rsf_zfs_event_logging:
  [boolean] When set to true, ZFS sysevents are logged to the RSF-1 log file
  (current events are cache file changes - use this option to ensure cache file
  synchronisation is occurring).
  [Default setting for NexentaStor: false.]


prop_zpool_import_option_m:
  [boolean] When set to true, zpool import supports the -m (import missing) option.
  [Default setting for NexentaStor: true.]


prop_abort_unfenced_import:
  [boolean] Prevents an unfenced pool being imported. When set to true, a pool in
  which no disk is persistently reserved will not be imported and the service set
  to broken_safe should an import be attempted.
  [Default setting for NexentaStor: true.]


prop_zpool_threads_option_t:
  [boolean] When set to true, enables parallel import/export pool mounts using threads.
  [Default setting for NexentaStor: true.]


prop_comstar_support:
  [boolean] Enables failover support for COMSTAR targets configured on clustered volumes.
  [Default setting for NexentaStor: true.]


prop_zpool_sync_cache:
  [boolean] Synchronize ZFS cache files between HA nodes whenever a ZPOOL cache is
  updated. The copy is instigated by a sysevent listener.
  [Default setting for NexentaStor: true.]


prop_zpool_run_dtrace_on_import:
  [boolean] Run dtrace on zpool import. This property is set by the zpool import
  process itself in response to an import operation taking longer than the
  property prop_zpool_dtrace_needed_timeout_seconds. Once the import time takes
  less than prop_zpool_dtrace_needed_timeout_seconds then this property is set
  back to false automatically.
  [Default setting for NexentaStor: false.]


prop_gui_res_drive_support:
  [boolean] When set to true enables reservation drive selection in the GUI rather
  than automatic generation. This ability in the GUI is being deprecated in
  favour of automatic drive selection.
  [Default setting for NexentaStor: false.]


prop_mhdc_use_pgr3:
  [boolean] When set to true, disk reservations will use PGR3. When set to false
  SCSI-2 reservations will be used.
  [Default setting for NexentaStor: false.]


prop_gui_cluster_initialized:
  [boolean] Set to true once the cluster has been initialized. This is a GUI
  initialization speedup that signifies a number of (one off) GUI checks have
  completed successfully and therefore do not need to be run again.
  [Default setting for NexentaStor: true.]


prop_skip_pgr3_log_and_cache:
  [boolean] When set to true, do not attempt to reserve the log and cache devices
  when using PGR3 reservations.
  [Default setting for NexentaStor: true.]


prop_gui_enable_fastfail:
  [boolean] When set to true enable the fast failover option in the GUI - reserved
  for future use.
  [Default setting for NexentaStor: false.]


prop_sync_rsfcdb:
  [boolean] When set to true the RSF-1 configuration database will be synchronised
  between all cluster nodes on any change.
  [Default setting for NexentaStor: true.]


prop_mhdc_use_failfast:
  [boolean] When set to true SCSI-2/PGR3 disk reservations have fail fast
  protection applied. Losing a reservation results in a system panic (and thus
  cross-mounts are avoided).
  [Default setting for NexentaStor: true.]


prop_event_notify:
  [boolean] When set to true send cluster events (such as service start/stop)
  through the event notifier interface.
  [Default setting for NexentaStor: true.]


prop_skip_vip_check:
  [boolean] When set to true, the initial VIP check done on service start is
  bypassed. Under normal circumstances this check should always be left on (i.e.
  the setting should be false).
  [Default setting for NexentaStor: false.]


prop_comstar_standby_luns_before_failover:
  [boolean] When set to true, COMSTAR LUNS wil be placed into standby before failover/deletion.
  [Default setting for NexentaStor: false.]


prop_zpool_threads_number:
  [numeric] Number of threads to run when option prop_zpool_threads_option_t is
  set to true.
  [Default setting for NexentaStor: 100.]


prop_zpool_dtrace_needed_timeout_seconds:
  [numeric] Threshold (in seconds) after which point the dtrace import/export
  scripts should be enabled for the next operation.
  [Default setting for NexentaStor: 180.]


prop_scsi2_drive_count:
  [numeric] Determines the number of disks in the pool on which SCSI-2
  reservations are applied.
  [Default setting for NexentaStor: 2.]


prop_scsi2_threaded_reserve:
  [boolean] When set to true, SCSI-2 reservations are issued in parallel and as
  such the total reservation/release time during poll import/export is reduced.
  Normally a SCSI-2 reserve takes on average 2 seconds, so reserving for example
  6 drives could takeadd up to 12 seconds to the overall fail over time -
  switching to parallel reservations means all 6 drives can be reserved in under
  two seconds. Due to a known issue with SAS disks, this option is disabled by
  default.
  [Default setting for NexentaStor: false.]


prop_zpool_dtrace_import_export:
  [boolean] Enable the running of custom dtrace scripts to trace ZPOOL
  import/export. This option is used in conjunction with the properties
  prop_zpool_run_dtrace_on_import and prop_zpool_run_dtrace_on_export - Please
  also reference their description to fully understand what these properties affect.
  [Default setting for NexentaStor: true.]


prop_use_zfs_cache:
  [boolean] When set to true, uses the ZFS cache file as part of the import to
  reduce the overall import time.
  [Default setting for NexentaStor: true.]


prop_gui_javascript_debug:
  [boolean] When set to true debugging messages are written to the browsers
  JavaScript console (when active). This option is not supported on IE browsers
  due to a bug in their JavaScript implementation.
  [Default setting for NexentaStor: false.]


prop_zpool_run_dtrace_on_export:
  [boolean] Run dtrace on zpool export. This property is set by the zpool export
  process itself in response to an export operation taking longer than the
  property prop_zpool_dtrace_needed_timeout_seconds. Once the export time takes
  less than prop_zpool_dtrace_needed_timeout_seconds then this property is set
  back to false automatically.
  [Default setting for NexentaStor: false.]


prop_gui_serial_hb_support:
  [boolean] When set to true allows the user to configure serial heartbeats in the
  cluster from the GUI.
  [Default setting for NexentaStor: false.]


prop_zpool_fail_mode:
  [string] Determines the behaviour of a catastrophic pool failure due to a loss of
  device connectivity or the failure of all devices in the pool. Options are:
  panic, continue, wait - see ZFS fail mode property for more details.
  [Default setting for NexentaStor: panic.]


prop_gui_enable_ipv6:
  [boolean] When set to true enables IPV6 support for Cluster VIPs along with IPV4
  in the Cluster GUI.
  [Default setting for NexentaStor: false.]


prop_zpool_export_option_c:
  [boolean] When set to true, zpool export supports the -c (flush cache) option.
  [Default setting for NexentaStor 3.x: false.]
  [Default setting for NexentaStor 4.x: true.]


prop_pgr3_drive_count:
  [numeric] Determines the number of disks in the pool on which PGR3 reservations
  are applied.
  [Default setting for NexentaStor: 0.]


prop_additional_common_directories :
  [string] Specifies a colon separated list of extra directories to search when a
  common (shared) startup directory is specified for a service in the service
  configuration. These directories will be searched to build up a list of
  scripts/programmes to execute when starting/stopping a service. Duplicate
  elements (i.e. those with the same file name found in more than one common
  directory) will be selected and executed from the first instance found by
  prioritising the property directory list over the service configured directory.
  For example with both /usr/rc.appliance.c/S01announce and
  /opt/HAC/RSF-1/etc/rc.appliance.c/S01announce the S01announce script from
  /usr/rc.appliance.c will be the only one run at service start time.

prop_cluster_hook:
  [string] A property that specifies an external command to be run during service
  start and stop. By default this property is emptyand therefore no action is taken.
  The properties use is intended to allow system integrators to build in their own
  start/stop hooks as required.

prop_ssh_bound:
  [boolean] Set to true when cluster nodes are bound together, otherwise false and
  no scp or ssh attempted.
  [Default setting for NexentaStor: true.]

prop_gui_disable_online_help:
  [boolean] Enables/Disables the showing of the About, FAQ menu items and manual
  page links in the title bar of each cluster panel.
  [Default setting for NexentaStor: false.]

prop_pool_hook:
  [string] A property specifying an external command to be run during pool import by
  S20zfs (and subsequent export by K80zfs). By default this property is empty and
  therefore no action is taken. The properties use is intended to allow system integrators
  to build in their own import/export hooks as required.

prop_gui_enable_comstar_browser:
  [boolean] When set to true reveals the COMSTAR browser GUI component.
  [Default setting for NexentaStor: false.]

prop_fping_retries:
  [numeric] Number of fping retries when performing VIP check prior to service startup.
  A value of 0 or -1 means just the one check, a numeric value means check this
  number of times if and only if the VIP is pingable on the first check. Ignored if the VIP
  is not detected before service startup.
  [Default setting for NexentaStor: 0.]

prop_gui_default_cluster_name:
  [string] The default name for a new cluster.
  [Default setting for NexentaStor: HA-Cluster.]

prop_scsi2_retry_count:
  [numeric] Sets the number of SCSI-2 TKOWN retry attempts when an I/O error is
  encountered back from the disk being operated on - set to 0 for no retries.
  [Default setting for NexentaStor: 0.]

prop_gui_default_runtimeout:
  [numeric] The default run timeout value for the cluster.
  [Default setting for NexentaStor: 8.]

prop_gui_default_inittimeout:
  [numeric] The default initial timeout value for the cluster.
  [Default setting for NexentaStor: 20.]

prop_gui_failover_state_sticky:
