I have been searching around to find documentation on this, but haven't really found anything yet.

Does anyone know if it is possible to use mdadm to "grow" a raid 5 array starting from a single disk (obviously not raid at this point) to 3 other disks?

Thanks.

Yes, it can reshape the array. See the mdadm man page.

I have never tried going up to raid 5, but I have started with a single disk raid1 then added the second drive.
