import cluster [--dryrun|-y] [--remove-angel] cluster_name
This command imports a MySQL NDB Cluster created independently of MySQL Cluster Manager
into a cluster named
that has been created in MySQL Cluster Manager. You are strongly advised to
cluster_name using the
option; see that command's description for more information
option and its effects.
import cluster requires a single argument,
the name of the cluster created using MySQL Cluster Manager
cluster_name) into which you wish to
import a MySQL NDB Cluster created externally into MySQL Cluster Manager and bring it
under MySQL Cluster Manager control. The cluster named in the command must
already exist in MySQL Cluster Manager.
import cluster also supports a
option. When this option is used, only the checks required for
importation are performed against the existing cluster. This
makes it possible to test a given configuration without actually
placing any cluster processes under MCM control.
is supported as a short form of this option.
For MySQL Cluster Manager 1.4.7 and later,
import cluster supports a
option. When this option is used, any running
processes for the data nodes of the cluster to be
imported are stopped by mcmd prior to the
actual import, which is a necessary step for a cluster import
unless the angel processes have already been stopped manually.
When this option is used together with the
option, no removals of angel processes will actually be
performed, but the checks for angel processes (which occur when
option is used alone) will be skipped. It is recommended that
you use the two options separately: perform the checks with the
option only, and once the only errors observed are with the
angel processes, run
cluster again with the
option only to complete the import.
