[Bug 1330172] [NEW] Unallocated space on one of two drives not offered for installation

[Ross Gammon]

Public bug reported:

I am trying to install the Ubuntu Studion Utopic (14.10) Daily Build ISO (of a week or so ago) onto some spare space of my main PC to assist the Ubuntu Studio team. However, I never get offered the drive with the spare space (neither in the automatic calculation of installation options, nor in the "something else" manual partitioning). Here is a rough outline of my set up:
- sda1-6 500GB Debian Testing
- sda 7 500GB UNALLOCATED
- sdb1-6 500GB Ubuntu 14.04 (my main working setup)
- sdb 7 500GB Debian Wheezy

Steps:
1. Boot into Ubuntu Studio 14.10 Daily Build Live DVD
2. Choose "install to disk" option
3. Select English, Click to get updates & non-free stuff, & continue
4. At the partitioning options screen, only sdb seems to be part of the calculation. Here is what is offered:
- Reinstall Ubuntu 14.04
- Erase Ubuntu 14.04
- Erase whole disk
- Something Else
Sda is completely ignored, except that it is the default option for installing the bootloader (which is where it currently is).
5. Choose "something else"
Only the partitions on sdb (and my sdc USB for backing up to) are visible, and there is no possibility of selecting sda.
6. Press Quit
7. In the Live Environment, run Gparted from the menu.
It can see everything including the unallocated space on sda.
8. Run ubiquity --debug from terminal
I will try and attach /var/log/installer/debug to the log.
