Description Bradley Childs 2013-12-05 00:29:16 UTC

Description of problem:
Using the RHS installer, I'm unable to create XFS partitions exceeding 2TB.

Version-Release number of selected component (if applicable):
2.1 most recent build

How reproducible:
Very reproducible on my setup (5TB RAID5 + 500GBx2 RAID1).  I have the 2x500GB as /, and formatting the 5TB RAID as an XFS brick.

Steps to Reproduce:
1.Obtain a system with >2TB drive plus a drive for system partitions.

2.Start GUI installer & manually configure the disks. Don't use LVM, and create a root partition on the smaller disks (ext4, mounted at /),  next try and create an XFS partition on the >2TB drive.  If you select "fill to maximum space" it will fill to 2TB and leave the rest free. If you try and type in a number >2TB it will error that "that size exceeds maximum allowable size".

Expected results:
Installer allows creation of XFS partitions > 2TB.

Additional info:

I might note that this is for testing&application performance profiling.  It may not be a well supported architecture. 

Also, I say "TB", but I did the MB->TB conversion in the installer.  The exact upper bound isn't known, but its somewhere around 2088576MB

This seems to be a limit on the partition size.  It appears that RHS installer is forcing MSDOS partition tables, which can not exceed 2GB.
