Create two empty disk images:
$ qemu-img create f18-test-1.img 11G
$ qemu-img create f18-test-2.img 12G

Complete two minimal installs with automatic storage configuration using the DVD:

$ qemu-kvm -m 2048 -hda f18-test-1.img -cdrom ~/xfr/fedora/F18/F18-Final/TC2/Fedora-18-TC2-x86_64-DVD.iso -usb -vga qxl -boot menu=on -usbdevice mouse

$ qemu-kvm -m 2048 -hda f18-test-2.img -cdrom ~/xfr/fedora/F18/F18-Final/TC2/Fedora-18-TC2-x86_64-DVD.iso -usb -vga qxl -boot menu=on -usbdevice mouse

Start the Live CD with both disk images and update the installer:

$ qemu-kvm -m 2048 -hda f18-test-1.img -hdb f18-test-2.img -cdrom ~/xfr/fedora/F18/F18-Final/TC2/Fedora-18-TC2-x86_64-Live-Desktop.iso -usb -vga qxl -boot menu=on -usbdevice mouse

Select both disks in Installation Destination.
Click Continue.
Check "I don't need help ..."
Click Reclaim space.
Click "+" to expand Unknown list.
Click "-" to delete.
Check "Delete all ..."
Click Delete it.
Click to automatically create default storage configuration.
Click Finish Partitioning.
Click Begin Installation.

Comment 9 Steve Tyler 2012-12-16 09:21:51 EST
Proposing as a blocker per F18 Alpha release criterion:[1]

9. The installer must be able to complete an installation using the text, graphical and VNC installation interfaces 

This could also apply:

12. The installer must be able to complete an installation using automatic partitioning to any sufficiently large target disk, whether unformatted, empty, or containing any kind of existing data 

The use case is moving a disk having a previously installed Fedora release to another system having a previously installed Fedora release and then reinstalling to use both disks.

Attempting to reproduce Bug 887539.
Selected sda, but not sdb, for volume group "fedora" containing "/" and "swap".

Package: anaconda-18.37.3-1.fc18.x86_64
OS Release: Fedora release 18

anaconda-tb-E0vu9v corresponding to Comment 11

For this log, both disks were selected, all partitions were deleted in Manual Partitioning, and the Modify dialog was used to select sda, but not sdb, for the volume group "fedora" containing "/" and "swap".

Tested with:
$ qemu-kvm -m 2048 -hda f18-test-1.img -hdb f18-test-2.img -cdrom ~/xfr/fedora/F18/F18-Final/TC2/Fedora-18-TC2-x86_64-Live-Desktop.iso -usb -vga qxl -boot menu=on -usbdevice mouse
Comment 13 Adam Williamson 2012-12-17 13:45:50 EST
steve: can you check what version of lvm2 you had in your test environment? We believe this may be a dupe of https://bugzilla.redhat.com/show_bug.cgi?id=876789 .

anaconda folks, can you comment if it's that bug, or a more detailed wrinkle?

Discussed at 2012-12-17 blocker review meeting: http://meetbot.fedoraproject.org/fedora-bugzappers/2012-12-17/f18final-blocker-review-5.2012-12-17-16.40.log.txt . We need more info (see above) to decide the status of this bug.

Comment 15 Adam Williamson 2012-12-21 14:18:09 EST
Discussed at 2012-12-21 blocker review meeting: http://meetbot.fedoraproject.org/fedora-bugzappers/2012-12-21/f18final-blocker-review-7.2012-12-21-18.33.log.txt .

anaconda team was able to diagnose this: it's caused by having two identically-named VGs (which in turn was caused by installing over two existing F18 installs). Given that this is a pretty odd corner case, this is rejected as a blocker. It's also rejected as NTH as anaconda team considers it too weird to fix this late, so there's no point accepting it as NTH.

Note that Final will have the hostname-setting stuff, so even if for some reason you really need to reproduce this scenario, you can just set different hostnames for the two initial installs and their VG names will be different. or directly set different VG names.
Comment 16 Steve Tyler 2012-12-21 14:40:14 EST
How is the use case described in Comment 9 "odd" or "weird"?

"The use case is moving a disk having a previously installed Fedora release to another system having a previously installed Fedora release and then reinstalling to use both disks."

A problem I am seeing with some of the blocker rationales is that they are ad hoc instead of persuasive.

Anyway, I look forward to reading the workarounds in "Common Bugs" ...

1. Start a terminal.
2. Read the parted man page.
3. Memorize the partition device names.
4. Blah, blah, blah.

Or maybe it starts with:
1. Remove one of the disk drives you just installed into your system.
2. ...

BTW, cloned disks will have the same hostname by definition.
Comment 17 Adam Williamson 2013-01-14 19:44:27 EST
steve: just because two disks both have Fedora on them doesn't mean they will have identically named VGs. It's in fact the least likely case. In releases prior to F18, you set a hostname before storage config, and the VG name was based on the selected hostname - so two disks will only have identically named VGs if the Fedora installs had identical hostnames (first part at least). I think you could edit the VG name in custom partitioning too. In F18 you definitely can, and the VG name will still be based on hostname if you set one in the Network spoke.
Comment 18 Fedora End Of Life 2013-04-03 09:40:27 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)
