I have a new 4TB disk on a new server which I'm installing Xen on.
I've always intended that I use whatever small partitions to get a
system up and running
and then dedicate the remaining balance of the disk to LVM.
After much hassle I finally got my Xen instance up on this EUFI based unit,
and I created a new partition, /dev/sda5, using fsdisk.
When I tried to create a new volume, I received a warning about
a vfat signature. I aborted.
Note: /dev/sda2 is a VFAT system which is required by EFI.
I had not previously create sda5, I just created sda1 - sda4 until
I finally had a dom0 server operating.
Here's the layout of the disk:
Device Start End Sectors Size Type
/dev/sda1 2048 6143 4096 2M BIOS boot
/dev/sda2 6144 268287 262144 128M EFI System
/dev/sda3 268288 1316863 1048576 512M Linux filesystem
/dev/sda4 1316864 42272767 40955904 19.5G Linux filesystem
/dev/sda5 42272768 7814037134 7771764367 3.6T Linux LVM
Here's my attempt to create a physical volume:
zeta jlpoole # pvcreate /dev/sda5
WARNING: vfat signature detected on /dev/sda5 at offset 54. Wipe it?
Aborted wiping of vfat.
1 existing signature left on the device.
Aborting pvcreate on /dev/sda5.

Is the warning something I need to be concerned about when
creating a physical volume on /dev/sda5? I'm wondering if it was
looking at another
partition and bubbling up just as a precaution.
