Expanding the source FlexGroup volume of a SnapMirror relationship

Starting with ONTAP 9.5, 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).

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

Example

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.
Do you want to continue? {y|n}: Y
[Job 146] Job succeeded: Successful
The state of all of the Snapshot copies that are taken before the volume is expanded changes to partial.
