25.6.17.53 The ndbinfo restart_info Table

The restart_info table contains information about node restart operations. Each entry in the table corresponds to a node restart status report in real time from a data node with the given node ID. Only the most recent report for any given node is shown.

The restart_info table contains the following columns:

• node_id

  Node ID in the cluster

• node_restart_status

  Node status; see text for values. Each of these corresponds to a possible value of node_restart_status_int.

• node_restart_status_int

  Node status code; see text for values.

• secs_to_complete_node_failure

  Time in seconds to complete node failure handling

• secs_to_allocate_node_id

  Time in seconds from node failure completion to allocation of node ID

• secs_to_include_in_heartbeat_protocol

  Time in seconds from allocation of node ID to inclusion in heartbeat protocol

• secs_until_wait_for_ndbcntr_master

  Time in seconds from being included in heartbeat protocol until waiting for NDBCNTR master began

• secs_wait_for_ndbcntr_master

  Time in seconds spent waiting to be accepted by NDBCNTR master for starting

• secs_to_get_start_permitted

  Time in seconds elapsed from receiving of permission for start from master until all nodes have accepted start of this node

• secs_to_wait_for_lcp_for_copy_meta_data

  Time in seconds spent waiting for LCP completion before copying metadata

• secs_to_copy_meta_data

  Time in seconds required to copy metadata from master to newly starting node

• secs_to_include_node

  Time in seconds waited for GCP and inclusion of all nodes into protocols

• secs_starting_node_to_request_local_recovery

  Time in seconds that the node just starting spent waiting to request local recovery

• secs_for_local_recovery

  Time in seconds required for local recovery by node just starting

• secs_restore_fragments

  Time in seconds required to restore fragments from LCP files

• secs_undo_disk_data

  Time in seconds required to execute undo log on disk data part of records

• secs_exec_redo_log

  Time in seconds required to execute redo log on all restored fragments

• secs_index_rebuild

  Time in seconds required to rebuild indexes on restored fragments

• secs_to_synchronize_starting_node

  Time in seconds required to synchronize starting node from live nodes

• secs_wait_lcp_for_restart

  Time in seconds required for LCP start and completion before restart was completed

• secs_wait_subscription_handover

  Time in seconds spent waiting for handover of replication subscriptions

• total_restart_secs

  Total number of seconds from node failure until node is started again

Notes

The following list contains values defined for the node_restart_status_int column with their internal status names (in parentheses), and the corresponding messages shown in the node_restart_status column:

• 0 (ALLOCATED_NODE_ID)

  Allocated node id

• 1 (INCLUDED_IN_HB_PROTOCOL)

  Included in heartbeat protocol

• 2 (NDBCNTR_START_WAIT)

  Wait for NDBCNTR master to permit us to start

• 3 (NDBCNTR_STARTED)

  NDBCNTR master permitted us to start

• 4 (START_PERMITTED)

  All nodes permitted us to start

• 5 (WAIT_LCP_TO_COPY_DICT)

  Wait for LCP completion to start copying metadata

• 6 (COPY_DICT_TO_STARTING_NODE)

  Copying metadata to starting node

• 7 (INCLUDE_NODE_IN_LCP_AND_GCP)

  Include node in LCP and GCP protocols

• 8 (LOCAL_RECOVERY_STARTED)

  Restore fragments ongoing

• 9 (COPY_FRAGMENTS_STARTED)

  Synchronizing starting node with live nodes

• 10 (WAIT_LCP_FOR_RESTART)

  Wait for LCP to ensure durability

• 11 (WAIT_SUMA_HANDOVER)

  Wait for handover of subscriptions

• 12 (RESTART_COMPLETED)

  Restart completed

• 13 (NODE_FAILED)

  Node failed, failure handling in progress

• 14 (NODE_FAILURE_COMPLETED)

  Node failure handling completed

• 15 (NODE_GETTING_PERMIT)

  All nodes permitted us to start

• 16 (NODE_GETTING_INCLUDED)

  Include node in LCP and GCP protocols

• 17 (NODE_GETTING_SYNCHED)

  Synchronizing starting node with live nodes

• 18 (NODE_GETTING_LCP_WAITED)

  [none]

• 19 (NODE_ACTIVE)

  Restart completed

• 20 (NOT_DEFINED_IN_CLUSTER)

  [none]

• 21 (NODE_NOT_RESTARTED_YET)

  Initial state

Status numbers 0 through 12 apply on master nodes only; the remainder of those shown in the table apply to all restarting data nodes. Status numbers 13 and 14 define node failure states; 20 and 21 occur when no information about the restart of a given node is available.
