To extend default disk space size for FastNetMon installs on VM you need to extend disk space from hypervisor size and reboot virtual machine.
First step to run parted to update total disk space size. parted will ask you about fixing GPT table, please accept it and answer with “Fix”.
sudo parted GNU Parted 3.2 Using /dev/sda (parted) print Warning: Not all of the space available to /dev/sda appears to be used, you can fix the GPT to use all of the space (an extra 167772160 blocks) or continue with the current setting? Fix/Ignore? Fix
As next step, please increase size of underlying partition used my LVM:
sudo parted GNU Parted 3.2 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Model: VMware Virtual disk (scsi) Disk /dev/sda: 107GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 2097kB 1049kB bios_grub 2 2097kB 1076MB 1074MB ext4 3 1076MB 21.5GB 20.4GB (parted) resizepart 3 100%
After finishing this step we will have 100G partition:
sudo parted (parted) print Model: VMware Virtual disk (scsi) Disk /dev/sda: 107GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 2097kB 1049kB bios_grub 2 2097kB 1076MB 1074MB ext4 3 1076MB 107GB 106GB
Next step will be extension of LVM physical volume:
sudo pvresize /dev/sda3 Physical volume "/dev/sda3" changed 1 physical volume(s) resized / 0 physical volume(s) not resized
sudo pvs PV VG Fmt Attr PSize PFree /dev/sda3 ubuntu-vg lvm2 a-- <99.00g 80.00g
Finally, extend LVM volume used for / partition to maximum size:
sudo lvresize -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv Size of logical volume ubuntu-vg/ubuntu-lv changed from 89.19 GiB (22833 extents) to <99.00 GiB (25343 extents). Logical volume ubuntu-vg/ubuntu-lv successfully resized.
Extend root filesystem:
sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv resize2fs 1.44.1 (24-Mar-2018) Filesystem at /dev/mapper/ubuntu--vg-ubuntu--lv is mounted on /; on-line resizing required old_desc_blocks = 3, new_desc_blocks = 13 The filesystem on /dev/mapper/ubuntu--vg-ubuntu--lv is now 25951232 (4k) blocks long.
After finishing process, please reboot virtual machine.
