On Windows since at least 2008, you have been able to expand a disk on a running virtual machine in VMware (or any other virtualization/SAN LUN) and then expand the disk/volume within Windows without needing downtime/maintenance.
We have SLES 11 VM’s with ext3 partitions in their LUNs. I’m sure that there has to be a way to do this. Is this possible with ext3, do I need to be using ext4, LVM, btrfs, I don’t know. I keep searching for this on the web and as soon as I think I’ve found the answer there is a “now, reboot the virtual machine” in it. Sorry I don’t have as much Linux experience as I do in Windows.
This might work, But its not advisable without a reboot.
this may or maynot work. http://raftaman.net/?p=228
