oci-utils

It will be great that if we can provide a guideline to install oci-utils on Ubuntu or debian-like system.

Per my experiment, libexec/oci-growfs works on ubuntu by its own but not so graceful

I second this, would be very useful.

@davidkhala did using libexec/oci-growfs work with another file system like ext4 (rather than XFS)?

I am not file system expert to give accurate advice. But since ext4 is default in Debian, and my experiment environment did not change the default, it should work.

Hi David I just tried running growfs and got this error on ubuntu : xfs_growfs: / is not a mounted XFS filesystem

was there a workaround or a flag you used to get it to work on ubuntu?

thank you.

Hi @KingPin,

What are the full steps to reproduce it?

Hi @davidkhala thank you for responding.

• I cloned this repo
• ran the libexec/oci-growfs command.

I saw no flags to be used with it so I simply used the command as is. it asked me if I wanted to resize, once I said yes it threw the error out at the end.

oci-utils is not supported on Ubuntu or Debian, has not been tested. tx. Guido

ok well just for any future google searchers ending up here, the error I posted above seems to be a warning and not an error. after a backup (please always backup) and a reboot the resizing seems to have been successful.

thanx @davidkhala for experimenting on this so I had the courage to try it out 💯

FYI, oci-growfs didn't work for me on Ubuntu but this guide did.

oci-growfs only handled xfs file systems; support for ext4 is in next release, support for Debian/Ubuntu is on the table but not yet decided. Guido

The script internally calls growpart from cloud-guest-utils and resize2fs. So if you are not using LVM etc, to grow main ext4 partition of a boot volume in Ubuntu, simply run:

sudo growpart /dev/sda 1
sudo resize2fs -z ./sda1.e2undo /dev/sda1

Since Oracle puts the boot partition after main, to be safe you can also install efibootmgr and check efibootmgr -v output. If yours also looks like

Boot0002* UEFI ORACLE BlockVolume       PciRoot(0x0)/Pci(0x12,0x7)/Pci(0x0,0x0)/SCSI(0,1)N.....YM....R,Y.

then it means it uses SCSI disk/partition number to locate boot partition and it should be safe to reboot now.

@Frederick888 Thank you, that worked flawlessly and you saved me a lot of headaches.

sudo resize2fs -z ./sda1.e2undo /dev/sda1

@Frederick888 If we don't want to keep a undo back up, can we skip the option -z ./sda1.e2undo here?

@davidkhala If it's what you want ¯\_(ツ)_/¯

This repo works for me on Ubuntu 22.04 out of the box. Had to do the following:

git checkout url-of-the-repo
cd oci-utils
python3 ./setup.py build
sudo python3 ./setup.py install
# the following will expand your volume(s)
sudo ./libexec/oci-growfs
