In my case I was resizing a data-only volume; the root file system and the rest of the O/S was on a different virtual disk. I don't use partitions on the data volume so partprobe is not of use (yes, I tried it). It will be a little while before I get the chance to try this out again, but I will report back when I do. In other news: anyone know how to boot RHEL/CentOS from a virtual disk that is more than 2GB in size? For example, if one has a PE2900 with eight 1TB drives, builds them into a single RAID-6 virtual disk, and installs the O/S. You get a GPT-format partition table, and the system cannot boot from that (at least, the install fails with a message to this effect).
