Extending an existing pool

[echodreamz]

Doing a manual extend of an existing pool, the button states "Add Volume" and clearly states existing data will be cleared. Is this a bug? Shouldnt it say "Extend Volume"?

I dont want to press it as I am afraid it will clear my existing volume data.

This is with v11.1.

Are you aware of the fact that adding a drive to a single RaidZ vdev is not possible without destroying all data and recreating the vdev?
