Hello,
I have been doing some testing on a new server before deployment. I came
across a limitation that I could not find documented and seems not to be
a limitation of any of the individual components. It also seems
restricted to the d-i.
I have been installing from the Debian Lenny amd64 DVD (5.0.4) and
Debian Squeeze (1st March 2010).
The issue is that the 6TB (RAID50 8*1TB on a 3ware 9650) is visible to
partman but not all usable. I have created a boot partition (256MB) and
then an LVM partition (the rest). The LVM partition stops at 4TB and the
remaining 2TB is listed as 'Free Space'. This can then not be used at
all. Any attempt to use this results in an error.
The partition type is GPT. The symptoms are the same on both Lenny and
Squeeze.
After continuing with the installation (on Squeeze) and using parted to
look at the disk, I get the following:
---
parted /dev/sda
GNU Parted 1.8.8.git-dirty
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.

Warning: Not all of the space available to /dev/sda appears to be used,
you can fix the GPT to use all of the space (an extra
3906207744 blocks) or continue
with the current setting?

I am unable, with parted, to extend the LVM partition as parted does not
seem to recognise LVM.
It seems to me that, maybe, libparted, partman or something related in
the d-i does not work with more than 4TB. All 6TB are shown but cannot
be used. As nothing seems to have a 4TB limit I am not sure what it
could be.
What filesystem did you select? May not be an LVM related limit, but
perhaps a filesystem limitation.
