I recently had a need to grow the root filesystem on a Photon OS 3.0 virtual machine. This is something I’ve done before with Ubuntu Linux (blog post here<\/a>), but Photon OS does not include the growpart<\/code> command out of the box, so that process did not work. <\/p>\n\n\n\n

After resizing the virtual machine disk, I rescaned from within the running OS (I could have also rebooted, but who wants to do that) by running this command:<\/p>\n\n\n\n

echo 1 > \/sys\/class\/block\/sda\/device\/rescan<\/code><\/p>\n\n\n\n

I then installed the parted utility with the command tdnf install parted<\/code> and started by typing parted<\/code> at the shell prompt. Once at the parted menu, I typed print<\/code> to show the disk information. A warning appeared letting me know there was extra space available for use and asking if I wanted to fix the GPT to use all the space, which I entered Fix<\/code> to accept.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

From here you can see that Disk \/dev\/sda has a size of 26.8GB, but the last partition #3 ends at 21.5GB. It happens that the last partition is the one I want to grow, so I type resizepart 3<\/code> . I’m notified that the partition is being used and I confirm with Yes<\/code>. To answer the new question for where I want the partition to end, I entered 26.8GB<\/code> which was the value previously returned by the print<\/code> command.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

With the partition table issues resolved, I entered quit<\/code> to exit the parted utility.<\/p>\n\n\n\n

Back at the shell, I ran resize2fs \/dev\/sda3<\/code> to resize the filesystem to consume all of the space. I can now confirm that my filesystem has the extra free space with the command df -h<\/code> .<\/p>\n\n\n\n

After testing this out, I realized the environment where I really needed to make the change did not have internet access, even through a proxy. Because of this I was unable to install parted with tdnf. Not to worry, we have two different workarounds for that.<\/p>\n\n\n\n

First, we can install the parted RPM manually without tdnf. To do this we browse to the Photon repo here: https:\/\/dl.bintray.com\/vmware\/photon_release_3.0_x86_64\/x86_64\/<\/a>. Looking through the list of packages, we find the one starting parted-*, in this case parted-3.2-7.ph3.x86_64.rpm. We download the file and copied it to the Photon VM (using WinSCP or the like). From our shell prompt we then run rpm --install \/tmp\/parted-3.2-7.ph3.x86_64.rpm<\/code> to install the manually downloaded RPM. We can then run the rest of the steps as outlined previously.<\/p>\n\n\n\n

Alternatively, if we don’t want to install parted in the guest and are okay with a brief outage, we could use a bootable CD image which contains partition management tools. One such tool that I’ve had good luck with is gparted. You can download the image here: https:\/\/gparted.org\/download.php<\/a>. This tool takes care of all the steps, both growing the partition and extending the filesystem. <\/p>\n","protected":false},"excerpt":{"rendered":"
