[Bug 1858161] [NEW] Ubuntu 18.04 install not reading block storage properly

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

We recently received Supermicro servers with Avago 3108 chipset, and 2x
Seagate 4K SAS drives in a hardware RAID1 configuration.

All other operating systems (including Ubuntu 16.04) report this virtual
drive properly.

Ubuntu 18.04 shows it as if it were using 512 byte sectors, instead of
the 4K sectors that are actually there.

Instead of having ~1TB drive, it shows as ~8TB and is unable to install
no matter what I do.

Going to shell during install and running fdisk shows all of the right
information and drive/sector sizes.

I am able to install 16.04 and then upgrade to 18.04, but that is not
ideal.

Please let me know what other information I can get, or how I can get it
for you.
