Resizable disk partition inside Linux VM – A server stack is the collection of software that forms the operational infrastructure on a given machine. In a computing context, a stack is an ordered pile. A server stack is one type of solution stack — an ordered selection of software that makes it possible to complete a particular task. Like in this post about Resizable disk partition inside Linux VM was one problem in server stack that need for a solution. Below are some tips in manage your linux server when you find problem about linux, ubuntu, hyper-v, , .
I’m trying to increase the size of the disk inside my virtual machine Ubuntu.
I used the following sequence of commands:
echo 1 > /sys/block/sda/device/rescan fdisk /dev/sda Command (m for help): d Partition number (1,2, default 2): 2 Command (m for help): n Select (default p): p
Now I see the following:
root@proj:~# parted GNU Parted 3.2 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) p Model: Msft Virtual Disk (scsi) Disk /dev/sda: 85,9GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 2097kB 1049kB bios_grub 2 2097kB 85,9GB 85,9GB ext4 (parted)
root@proj:~# fdisk /dev/sda Welcome to fdisk (util-linux 2.31.1). Changes will remain in memory only, until you decide to write them. Be careful before using the write command.

I use Webmin to manage my server, and after rebooting it continues to say that:
Mounted As Type Free Total Device ID / ext4 41% (15.70 GB) 38.37 GB UUID=1f76306d-c5e9-45d8-ae14-923bb1114c16 Local disk space 22.67 GB used / 15.70 GB free / 38.37 GB total
I am new to these issues, help me understand, please, what is my mistake?
Making the partition larger is a necessary, but not sufficient, step in making the space available to the operating system. You also need to modify the metadata in the filesystem, which is the algorithm by which the raw space in the partition is made available to store files, directories, permissions, and so on.
Given the details provided, the most likely command you need to run is
