UFS Growing Disks

[TobiasW]

Hello everybody,

I tried to grow a UFS Partition inside a virtualbox VM (.vhd disk format).

I went trough https://www.freebsd.org/doc/handbook/disks-growing.html and everything was fine until

growfs /dev/ada1p3
Operation not permitted

occurred.

I googled a bit around and found following thread

404 - Page not found

404: The page you requested could not be found.

www.digitalocean.com

and noticed that
growfs /dev/gpt/rootfs
worked smoothly.

Is this intended? Might it be a good idea to add a note to the documentation?

Best,
Tobias

You can file a PR (patch), and suggest a change in that section of the handbook.

There is a bug report on this already PR 237392. Maybe Post there.

I have the same problem here:

UFS - How to resize the root partition after enlarging the hard disk?

I have a virtual machine with FreeBSD inside Virtualbox, the disk is 20GB let's say, and want to enlarge it to 50GB. With Virtualbox tools I just enlarge the disk no problem, but how do I do to resize the root filesystem, which is a freebsd-ufs type at /dev/ada0p4 device?

Maybe is that you should not be able to use growfs on mounted filesystems?

The growfs(8) man page says that you should be able to resize mounted filesystems (well, from FreeBSD version 10 at least).

Thanks a lot! Let's see if some update fixes it.

A (simple alternative is):
- Backup ,delete-partition , recreate-partition, copy-over.

The idea is to do it from live / system. If I'm to destroy my root I just reboot to live cd and do it from there, since it works.
