WAG? Is there a partition on the lv that the installer can find? I run into this all the time when using an lv storage pool and an lv based virtio drive. I first have to fdisk the newly allocated drive and do a partprobe before the vm guest will recognize that it has the space.
The volume actually did contain a partition table, but I added it after accidentally formatting it as ext4. This confused the installer.
Zeroing out the first 5k bytes and recreating the partition table with fdisk fixes the issue.
I can reproduce this. When adding a partition table with fdisk after having formatted the volume (as ext4) the installer does not pick up the volume. Zeroing out of a few sectors (5k works, less might work too) and recreating the partition table and the installer sees the volume.
Thank you for pointing me in the right direction.
