Well, F29 is very close to EL8 but you are right. Anyway, for the sake of precision. 
I made the same installation with RHEL8 (anaconda 29.19 vs 29.24 on F29). The results 
are same!

Following "logvol" stanza "--percent=100 --grow" works for EL7 but not for EL8.

While doing this again I found a solution; "--size=SIZE --grow" as options with an 
arbitrary SIZE will grow the LV to the size of the free VG size.
