I've tried that, it returns a warning about kernel unable to reread partition table and requiring a reboot to see any modifications. Then the next call to pvcreate fails as it can't find the partition.

Quoting "Smithies, Russell" Russell.Smithies@agresearch.co.nz:
Perhaps I'm doing it wrong then.
1). In Vmware, extend the existing disk by changing the provisioned size in the vSphere client. 2). In Centos, create an additional partition with fdisk, 3). Somehow reread the partition table without rebooting?? 4). pvcreate 5). vgextend 6). lvextend 7). resize2fs
What I find is that without a reboot, the OS doesn't see the partition so can't pvcreate etc.

I don't believe partprobe works when you change the partitiontable of the disk that the root filesystem is on. I could be remembering it wrong.
