Quickly reading over the report I would think this is a result of the installer bug I reported as bug #1447167. The problem is that if you configure a system for multipath, it will present each path as an independent drive. And that causes a lot of confusion when a system has data on those and comes up without the multipath tools installed. To the OS this looks like multiple disks having the same filesystem UUIDs which conflict when creating disk-by/... links in /dev. Even worse LVM finds two PVs with the same ID and bails (iirc). I theory (with a lot knowledge and care) it is possible to install single-path and convert the whole system to multipath later. But frankly I think when the installer was told to enable multipath detect, it should automatically install the tools.

But I do know that writing data to sda causes that data to be readable from sdg. The same is true: sda -> sdg sdb -> sdh That is what causes those UUIDs to be similar. Everything is functional, you just have to know that if your root device is /dev/sdg that you should probably not write data to /dev/sda thinking you can use it as a disk.
