> Hello, sorry for the long email, it's a little hard to explain this issue. The gist of it is that the Ubuntu version of parted allowed me to do something which perhaps should not be allowed i.e. creating partitions on a 2.7TB drive when the partition table is not *gpt* but *msdos*.

There are slight differences between the BIOS versions and Firmware versions of the LSI disk controller, etc but I'm not sure that matters in this case.

Since the disk is larger than 2TB, I had to use 'parted' to create the partitions. So I happily created the partitions I wanted which are below:

I think it is not possible to create partitions lager than 1.7TB
without gpt partition table.

Of course you can create small boot partition and some lvm partitions
and combine them to one big lvm volume or use another drive for
booting and use gpt partition table for big disk..
