vinfra cluster create

Create a storage cluster:

usage: vinfra cluster create [--disk <disk>:<role>[:<key=value,…>]]
                             [--tier-encryption {0,1,2,3}] --node <node>
                             <cluster-name>

--disk <disk>:<role> [:<key=value,…>]

Disk configuration in the format:

• <disk>: disk device ID or name
• <role>: disk role (cs, mds, journal, mds-journal, mds-system, cs-system, system)
• comma-separated key=value pairs with keys (optional):
  • tier: disk tier (0, 1, 2 or 3)
  • journal-tier: journal (cache) disk tier (0, 1, 2 or 3)
  • journal-type: journal (cache) disk type (no_cache, inner_cache or external_cache)

  • journal-disk: journal (cache) disk ID or device name

  • bind-address: bind IP address for the metadata service

Example: sda:cs:tier=0,journal-type=inner_cache.
This option can be used multiple times.

--tier-encryption {0,1,2,3}

Enable encryption for storage cluster tiers. Encryption is disabled by default. This option can be used multiple times.

--node <node>

Node ID or hostname

<cluster-name>

Storage cluster name

Example:

# vinfra cluster create stor1 --node 94d58604-6f30-4339-8578-adb7903b7277
+---------+--------------------------------------+
| Field   | Value                                |
+---------+--------------------------------------+
| task_id | d9ca8e1d-8ac8-4459-898b-2d803efd7bc6 |
+---------+--------------------------------------+

This command creates a task to create the storage cluster stor1 on the node with the ID 94d58604-6f30-4339-8578-adb7903b7277. As disk roles are not explicitly specified, they are assigned automatically: mds-system to the system disk, and cs to all other disks.

Task outcome:

# vinfra task show d9ca8e1d-8ac8-4459-898b-2d803efd7bc6
