I have rather old ESXi 6.0 that hosts a vm with Ubuntu. I need to increase the disk for it.
I don't have vmware-vdiskmanager as advised in

Here are the steps that worked for me:
On ESXi
Find vm id:
vim-cmd vmsvc/getallvms And power off:
vim-cmd vmsvc/power.off 6 Resize the vmdk file (specify xxxxx.vdmk instead of xxxxx-flat.vmdk):
vmkfstools -X 500G xxxxx.vmdk Power on vm:
vim-cmd vmsvc/power.on 6 On guest vm
Use parted and resize2fs:
$ sudo parted GNU Parted 3.3 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: 537GB 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 500GB 500GB ext4 (parted) (parted) (parted) resizepart 2 Warning: Partition /dev/sda2 is being used.
