NAME

esxi-grow-disk - grow a VM disk without reboot

EXAMPLES

# Part1:
# In the esxi GUI increase the VM's disk size.

# Part2:
# Open a shell to your VM and tell the kernel to rescan your device. In this case sda.
$ echo 1 > /sys/class/block/sda/device/rescan

# Install growpart
$ yum install cloud-utils-growpart
$ apt install cloud-guest-utils

# Expand your partition using growpart. (Yes there is a space between /dev/sda and the partition number. Odd syntax right?)
$ growpart /dev/sda 2

# And finally resize your file system to the newly acclaimed space
$ resize2fs /dev/sda2
