You tried to grow past the end of the volume.

So you have allocated 1023.04GB of your volume group. I assume
that's a single 1023GB logical volume that you have XFS on.

Hence if you want your XFS filesystem to be larger than 1023GB, then
you need to grow your logical volume to larger than 1023GB
first.....

Cheers,

Dave.
