#get(opts = {}) ⇒ GlusterVolume

Get the gluster volume details.

For example, to get details of a gluster volume with identifier 123 in cluster 456, send a request like this:

GET /ovirt-engine/api/clusters/456/glustervolumes/123

This GET request will return the following output:

<gluster_volume id="123">
 <name>data</name>
 <link href="/ovirt-engine/api/clusters/456/glustervolumes/123/glusterbricks" rel="glusterbricks"/>
 <disperse_count>0</disperse_count>

  • :headers (Hash) — default: {}

    Additional HTTP headers.

  • :query (Hash) — default: {}

    Additional URL query parameters.

    Gluster volume profiling information returned from the action.

  • :headers (Hash) — default: {}

    Additional HTTP headers.

  • :query (Hash) — default: {}

    Additional URL query parameters.

end

#rebalance(opts = {}) ⇒ Object

Rebalance the gluster volume.

Rebalancing a gluster volume helps to distribute the data evenly across all the bricks. After expanding or shrinking a gluster volume (without migrating data), we need to rebalance the data among the bricks. In a non-replicated volume, all bricks should be online to perform the rebalance operation. In a replicated volume, at least one of the bricks in the replica should be online.

For example, to rebalance a gluster volume with identifier 123 in cluster 456, send a request like this:

POST /ovirt-engine/api/clusters/456/glustervolumes/123/rebalance

Parameters:

  • opts (Hash) (defaults to: {})

    Additional options.

Options Hash (opts):

  • :async (Boolean)

    Indicates if the rebalance should be performed asynchronously.

  • :fix_layout (Boolean)

    If set to true, rebalance will only fix the layout so that new data added to the volume is distributed across all the hosts. But it will not migrate/rebalance the existing data. Default is false.

  • :force (Boolean)

    Indicates if the rebalance should be force started. The rebalance command can be executed with the force option even when the older clients are connected to the cluster. However, this could lead to a data loss situation. Default is false.

  • :headers (Hash) — default: {}

    Additional HTTP headers.

  • :query (Hash) — default: {}

    Additional URL query parameters.

  • :timeout (Integer) — default: nil

    The timeout for this request, in seconds. If no value is explicitly given then the timeout set globally for the connection will be used.

  • :wait (Boolean) — default: true

    If true wait for the response.
