Hi,
I have a 24TB RAID6 disk with a GPT partition table on it. I need to partition it into 2 partitions one of 16TB and 1 of 8TB to put ext4 filesystems on both. But I really need to do this remotely. ( if I can get to the site I could use gparted )
Now fdisk doesn't understand GPT partition tables and pat

You have to use either parted or gparted, and as much as I prefer command line, parted is user hostile; gparted's just the gui on top of parted. It works fine, AFAIK, though I've only used it on 3TB drives.

I've used parted on 10TB and up disk arrays with no problems. I wouldn't call parted's CLI "hostile", but I would definitely suggest having the docs close by.

Hostile: I start parted up with -optimum, and it still doesn't set the default start for a partition by itself, nor does it suggest in any way, shape, or form what it wants you to do. You have to google to find out.

Install gdisk from EPEL. Syntax is very similar to fdisk, and saner if you're used to fdisk versus parted. Home page is at http://www.rodsbooks.com/gdisk/

Is there any reason why you can't just use a whole disk LVM PV and then use LVM to create VGs and LVs of the required size?

OOPS that was fat fingers. I didn't mean to send it.
I figured out parted can do the job for me but the interface is not the best. Can't use gparted as I said I have to do this remotely.
I'll certainly have a look at gdisk
Sorry for the noise. I'll let people know how I get on after the weekend.

Even if you need to do this remotely, you can use gparted through ssh with X11 forwarding.

If you consider resizing your RAID volumes one day, I'll recommend the already proposed solution: use LVM, with physical volume directly on the disk device. No partitionning. Why ? Because, as far as I known, parted developers has decided to remove the unmaintained/old code to resize ext* filesystems from parted.
I don't know about gdisk features. Perhaps, it can do better than parted...

Worked like a dream. Can't understand how I didn't think of looking for an rpm of gparted. I only ever used the live-cd version before. Thanks.

The partition sizes required are fixed for their lifetime so LVM is not needed only adding complexity.
