I've been trying to increase the partition size on one of our servers as it was created years ago and was set too small. I've increased the size in the VM that hosts this but now I'm trying to get Linux to know we've allowed more space.
The details from fdisk /dev/sda are below
root@server:~# fdisk /dev/sda
Welcome to fdisk (util-linux 2.25.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

So I want to increase sda6 to 70GB, what is the best way to go about this? I can't use parted as the package isn't installed and the server currently has no internet access. I've tried doing it via fdisk by deleting the partition and recreating it larger, but when I try and mount it I get errors regarding superblocks.
Any help would be great. Thanks!
