Adds a new subcluster to an Eon Mode database.

Adds a new subcluster to an Eon Mode database. For details, see Creating subclusters.

Syntax

vcluster add_subcluster options

Required options

--catalog-path string: The absolute path to the catalog directory.

{ -c | --config } string: The path to the config file. If a configuration file is present in the default location (automatically generated by create_db), you do not need to specify this option.
Default: /opt/vertica/config/vertica_cluster.yaml

--subcluster string: The name of the new subcluster. This string must conform to the format used for database names.

Options

--cert-file string: The absolute path to the certificate file. If you specify this option, you must also specify --key-file. You should only use --cert-file and --key-file if you have configured the Node Management Agent (NMA) to use custom certificates.

--control-set-size int: The number of control nodes in the subcluster.
Default: -1 (All nodes in the subcluster are control nodes)

--data-path string: The absolute path to the data directory. This should be the same for all nodes in the database.

--depot-path string: [Eon only] The absolute path to depot directory.

--depot-size string: [Eon only] Size of depot in one of the following formats:

integer{K|M|G|T}, where K is kilobytes, M is megabytes, G is gigabytes, and T is terabytes.
integer%, which expresses the depot size as a percentage of the total disk size.

--force-removal: Whether to delete any existing database directories in the new hosts before attempting to add them.

{ -h | --help }: Prints help text.

--ipv6: Whether the hosts use IPv6 addresses. Hostnames resolve to IPv4 by default.

--is-primary: Whether the new subcluster should be a primary subcluster. If this option is omitted, new subclusters are secondary.

--key-file string: Path to the key file. If you specify this option, you must also specify --cert-file. You should only use --cert-file and --key-file if you have configured the Node Management Agent (NMA) to use custom certificates.

{ -l | --log-path } string: The absolute path for debug logs.
Default: /opt/vertica/log/vcluster.log

--new-hosts string[,...]: A comma-separated list of hosts or IP addresses to add to the subcluster.

{ -p | --password } string: The database password.
Default: "" (None)

--password-file string: The absolute path to a file containing the database password.
If you pass - (that is, --password-file -), the password is read from STDIN.

--read-password-from-prompt: Prompt the user to enter the password.

--skip-rebalance-shards: [Eon only] Whether to skip shard rebalancing.

--verbose: Show the details of VCluster run in the console

Examples

To add a primary subcluster with one control node:

$ vcluster add_subcluster --subcluster sc1 \
  --config /opt/vertica/config/vertica_cluster.yaml \
  --is-primary --control-set-size 1

To add a secondary subcluster with one control node containing the new node 192.0.2.4:

$ vcluster add_subcluster --subcluster sc1 \
  --control-set-size 1 --new-hosts 192.0.2.4
