Expand the source FlexGroup volume of a SnapMirror relationship

Contributors

Starting with ONTAP 9.3, you can expand the source FlexGroup volume of a SnapMirror relationship by adding new constituents to the source volume. You can expand the source volume in the same way that you expand a regular FlexGroup volume (read-write volume).

Steps
  1. Expand the source FlexGroup volume: volume expand -vserver vserver_name -volume fg_src -aggr-list aggregate name,... [-aggr-list-multiplier constituents_per_aggr]

    cluster1::> volume expand -volume src_fg -aggr-list aggr1 -aggr-list-multiplier 2 -vserver vs_src
    
    Warning: The following number of constituents of size 50GB will be added to FlexGroup "src_fg": 2.
    Expanding the FlexGroup will cause the state of all Snapshot copies to be set to "partial".
    Partial Snapshot copies cannot be restored.

    The state of all of the Snapshot copies that are taken before the volume is expanded changes to partial.
