How to hot add disk to a filesystem
Hey all, thanks for taking a moment to read and perhaps provide me some insight.
I have virtualized Linux machines that have base configurations on them, including disk size. I realize that over time one, or more, of those Linux VMs may experience a disk capacity issue. As such, I would like to identify a way to hot-add data disk to the VM without incurring an outage to the disk. Windows 2008 R2 can do this, so I have to believe Linux can also, after all, Microsoft surely steals the best ideas they have from the Linux community. (Note, I'm talking about extending data disk, not the root partition.)
I've Googled this to no end and every solution I've tried always causes an outage to the disk. I am going to attribute this to my inability to Google. ;-)
Thanks in advance.
