What is NOT obvious: for single device installs, if you omit the size in the create mount point dialog, the size of the resulting volume will consume all remaining space. But since there's no way to preset raid5 at the time a mount point is created (raid5 is set after the fact), there isn't a clear way to say "use all remaining space for this". There's just a size field for the volume, and a space available value in the lower left hand corner.

close, but then, for mysterious reasons, Red Hat decided to cripple it into oblivion. Go figure.
One word: desktop. That's what they want to conquer next.
I love CentOS, been using it since 4.x. But frankly, CentOS 7's installer is an abomination.
All's well that ends well. It only took me a day and a half to figure out how to configure RAID 5 using the graphical assistant. Something I could have done in less than three minutes using fdisk and mdadm --create.
We don't want to use lvm - my manager doesn't like it, and given how much we hit our machines, we almost don't use vm's, either - we need all CPU cycles for some things (like heavy scientific computing).
We also pretty much don't use any drives under 1TB. The upshot is we had custom scripts for > 500GB, which made 4 partitions - /boot (1G, to fit with the preupgrade), swap (2G), / (497G - and we're considering downsizing that to 250G, or maybe 150G) and the rest in another partition for users' data and programs. The installer absolutely does *not* want to do what we want. We want swap - 2G - as the *second* partition. But if we use the installer, as soon as we create the third partition, of 497GB, for /, it immediately reorders them, so that / is second.
Duh....
The result is that we get to the screen to choose the drive, and say "custom partition"... then <alt-F2>, and use parted to make the partitions, then go back to the GUI and just assign the mount points and filesystem types.
And why would you *want* / to have everything? I want to be able to install a newer o/s, or whatever, and not have to worry about all the data, etc - I want that in a separate partition (no, don't format that, thank you).
