[Gllug] Max VG size in LVM 2

[Iain M Conochie]

Afternoon,

  I am trying to find some information about the maximum size a Volume 
Group can be under LVM2. The distro we are using is CentOS 4.4 (this 
could be upgraded to 5)

  I can see that the old LVM1 had size limits with regards to Physical 
Extents so the PE size was critical in creating the logical volume when 
planing to have large VG's. However I can find no such details with 
regards to LVM2.

  Currently the server has a 3.1 TB VG which is created from 1 LUN from 
a SAN, but we are looking to expand this as more space is needed.

Any ideas?


Iain
