Resize drive and partition on FreeBSD 12 (pfSense)

By 1 min read

Recently I described how to increase drive, partition and filesystem on FreeBSD in Azure virtual machine. It turned out that this scenario was little bit different from a virtual machine running on top of VMware. First of all, with or without vm-tools I was not able to get updated drive size:

Text
camcontrol rescan all

It gives messages that rescanning was successful, but actually it did not apply new values. However we can check new drive size with the following command:

Text
camcontrol readcap da0 -h    # daX

If on your system you get same results, then you need to reboot.

There is also a difference of having swap space. First disable it:

Bash
cat /etc/fstab               # pick swap device to use
swapoff /dev/label/swap0     # as an example

Then remove swap partition as freebsd-ufs partition need to be a continuous space:

Text
gpart delete -i 2 da0s1      # refer to gpart show

Then as previously run resizing commands:

Bash
gpart resize -i X da0        # X would be probably 1
service growfs onestart

Now you are done.

    In case you’ve managed to overcome other issues with system unable to boot, disk size not updated then there might be still one problem left. Sometimes resizing with gpart works fine but file system resize does not.
