pgd node part v6.2.0

Synopsis

The pgd node part command removes a PGD node from an active cluster, initiating the parting operation.

The behavior of this command is conditional based on the cluster's Raft protocol version:

  1. Raft protocol version 6003 and above

    In this scenario, all PGD nodes in the cluster are running version 6.2.0 or above.

    The system immediately renames the node to its UUID and continues the complex parting operation in the background. This action allows you to rename the node's original name before the whole operation completes.

    After the initial part command returns, use the node's UUID-based name to track the progress of the parting node.

    The --no-wait option is deprecated in this scenario.

  2. Raft protocol version below 6003

    In this scenario, not every PGD node in the cluster is running PGD version 6.2.0 or above.

    By default, the command waits for the entire part operation to complete. If you use --no-wait, the system schedules the part operation in the background and immediately returns an advisory message, without waiting for completion.

Syntax

Where <NODE_NAME> is the name of the node to be parted.

Examples

Part a node (Raft protocol version 6003 and above)

pgd node pgd-a1 part
Output

Part a node with --no-wait option (Raft protocol version below 6003)

pgd node pgd-a1 part --no-wait
