On C6 (latest) I wanted to add an extra partition, number 14, to a 1TB GPT disk.
It failed repeatedly. The error message is:-

Does C6's version of Gparted work with GPT disks ?
Thanks.

Is the disk or 1 of its partitions mounted ? If so, can it be unmounted ? $0.02, no more, no less ....

Hi William, its the only HDD on that machine. All the partitions are mounted. The error message refers to the HDD, not to any of the mounted partitions.

Thanks.

Firstly, if at all possible, you're better off doing it with disks unmounted, booting from a gparted live CD.
Secondly, if that's not practical, that message is common when using, say fdisk. Sometimes, running partprobe afterwards will reflect the new partition scheme, other times, you may just have to reboot.

I always assumed that it was impossible to have the kernel re-read the partition table of a drive with mounted filesystems. But apparently it isn't. Here's some possibly interesting detail on what partprobe does.

It's possible fdisk doesn't do this. I don't know enough about parted, but it's also possible it lets partprobe do it instead of doing it itself.

On C6, kernel 2.6.32-573.26.1.el6.x86_64, GParted did not succeed using
GParted 0.19.1 Libparted 2.1
On C5, kernel 2.6.18-410.el5, Gparted succeeds with some HDDs, but not others, using
GParted 0.4.8 Libparted 1.8.1
Using a 'rescue' disk, Parted Magic 2013_02_28, I ran Gparted version 0.14.1 Libparted 3.1 on a Linux kernel of 3.7-9-pmagic. It created the partitions and formatted them without problems.
Never had a gui partition creation problem when installing from C 6.5 minimum install disk
Have I found a bug in C6 ?
