[ale] partition size increase, using commandline, while VM running - HowTo ?

[Lightner, Jeff]

Wasn’t the original question about the partition rather than the filesystem?

One would need to increase the size of the partition prior to increasing the size of the filesystem.

parted is the command line interface whereas gparted is the GUI interface so you can do it with parted (look  at the –s option for script) in man page.

Failing that you can probably use fdisk which is the older partitioning tool.  (It has issues with some disks/partitioning schemes)

I did not think from the btrfs perspective.  I will try that approach.  Thank You.

btrfs man page? Isn't easier management THE reason for it?  Google found:

Did that not work (assuming btrfs)?

I must be misunderstanding something.
