[linux-lvm] Beginner Questions

[Joseph L. Casale]

Hi,
I have Fedora Core 7 with  LVM version: 2.02.24 (2007-03-19), Library version: 1.02.17 (2007-01-29) and  Driver version: 4.11.0 setup.

I have two hardware raid cards each with one array partitioned fully at 799.9GB and 1499.9GB. When I try run to pvcreate /dev/sdb1 /dev/sdc1 it creates the pvs and when I run pvdisplay I get this:

  --- Physical volume ---
  PV Name               /dev/sdb1
  VG Name               name
  PV Size               745.00 GB / not usable 3.67 MB
  Allocatable           yes
  PE Size (KByte)       4096
  Total PE              190718
  Free PE               190718
  Allocated PE          0
  PV UUID               yQyVCe-tiS4-Ma1E-hilJ-niuG-KXL9-jkKVIk

  --- Physical volume ---
  PV Name               /dev/sdc1
  VG Name               name
  PV Size               1024.00 GB / not usable 8192.00 EB
  Allocatable           yes
  PE Size (KByte)       4096
  Total PE              357626
  Free PE               357626
  Allocated PE          0
  PV UUID               PURHhY-Lo1T-5bif-HjGP-dP3o-NVTs-71ZKUm

Why is some space "not usable"?

Thanks!
