Re: [CentOS] pvcreate limitations on big disks?

OK folks, I'm back at it again. Instead of taking my J4400 ( 24 x 1T disks) and making a big RAID60 out of it which Linux cannot make a filesystem on, I'm created 4 x RAID6 which each are 3.64T

I then do :

sfdisk /dev/sd{b,c,d,e} <<EOF ,,8e EOF

to make a big LVM partition on each one.

But then when I do :

pvcreate /dev/sd{b,c,d,e}1

and then

pvdisplay

It shows each one as only half its actual size.

You need to use GPT partition table to manage above 2TB. Traditional DOS partition can't manage above 2TB. fdisk can't work with GPT, it's possible sfdisk don't work too.

Try using parted /dev/device, and mklabel GPT
