Comment 3 for bug 408580

I'll check the number of metadata areas when I get home, but this sounds like a plausible explanation. From some brief googling, it seems like the number of LVM metadata areas for "large" disks is now 2 by default. Not sure what their threshold is, but I would certainly expect that my 1.5 TB Samsung drive is "large". OTOH, the disk on which I was successful (with a MSDOS label) was not nearly as large - 250GB.

Where can I go to get the upstream version - preferably in the form of a rescue disc ?
