Plans can be in these states:
APPROVED
The plan has been created, but is not yet running.
RUNNING
The plan is currently executing.
SUCCEEDED
The plan has completed successfully.
INTERRUPTED
A RUNNING plan has been
manually interrupted, using the
interrupt command in the
CLI.
INTERRUPT REQUESTED
A plan has been manually interrupted, but is still processing the interrupt request. A plan may have to cleanup or reverse steps taken during plan execution to be sure that the store remains in a consistent state.
ERROR
A RUNNING plan has
encountered a problem, and has ended without
successfully completing.
CANCELED
An INTERRUPTED or
ERROR plan has been
terminated using the CLI. To cancel a plan using
the CLI, use the cancel
command.
Plans in INTERRUPTED,
INTERRUPT REQUESTED or
ERROR state can be retried using
the plan execute command. Retrying
may be an appropriate approach when the underlying problem
was transient or has been rectified. Plans that are
retried simply re-execute the same steps. Each step is
idempotent, and can be safely repeated.
Note that Storage Nodes and Replication Nodes may
encounter errors which are detected by the Admin Console
and are displayed in an error dialog before the plan has
processed the information. Because of that, the user may
learn of the error while the Admin service still considers
the plan to be RUNNING and active. The
plan eventually sees the error and transitions to an
ERROR state.
