I would like to know if these are known issues before opening a ticket

The first is a bug in disk druid at install time. If you have a Volume
group with a logical volume larger than 2TB you can't edit the default
setup parameters in disk druid. For example I have a Dell poweredge 2950
with 6x750GB in RAID5 using the parc 5/i. By default these servers come
configured with two virtual disks. Using Red Hat's default layout it
will use LVM and combine the two disks into one volume group. this makes
the root logical volume about 3.5Tb. The size listed is not correct. It
shows 3.57229e+06. If you try to edit the logical volume name or group
and click ok it will say that the amount of space allocated is too large
and gives a range of 0 to 2TB. Even manually typing in the amount shown
as available(3574272) gives the same error. Of course if you leave it
alone it will format the volumes and work just fine.
The second bug is that if I use the perc 5/i and create one volume of
3.5TB, RHEL5 will kernel panic during boot. I'm guessing that RHEL5
cannot use physical drives over 2TB for the /boot or / partition? Again
I used Red Hat's default partition layout.
I have the same server, same configuration, and had the same problem.
It turns out not to be a bug at all, just too big for BIOS to boot from.
What I ended up doing was creating a 40GB raid5 partition from the
perc/5i setup, then create a second raid5 partition (3.4TB). Install
linux easily on the 40GB slice, then use parted to select the slice as
GPT, format and use.
Hope this helps...
