[linux-lvm] [Fwd: Best way to create a 540GB LVM Volume?]

I've got 14 FC1 disks in a PV660F. I want to take 7 of them and make a large volume. I can't seem to make a > 450 GB volume though, even though lvdisplay is showing xxMB PE free.
I'm using default 4mb and also 8mb extentsize when creating the VG. Please advise.

Austin,
the maximum of 450GB you mention below sounds strange.
did you use "vgcreate -s physicalextentsize ..." when you created the volume group?
Unless you set a larger extent size than the default of 4MB with the -s option, you can't create logical volumes larger than ~256GB.
"vgcreate -s 32m ..." for eg. would enable ~2TB maximum logical volume size which is the maximum per single block device Linux up to 2.4 supports anyway.
In LVM2 (please check the beta code on our web site www.sistina.com) there'll be no extent size related constraints any longer, because we support additional ondisk formats in parallel. LVM2 is format compatible with the LVM1 format as well.
Regards,
