Extending your OCI VM Boot Volume

This is a small post to remember how to extend an OCI VM Boot volume to benefit from more than the default 35.5G.

First, create a VM with a customized boot volume, say: 200G.

Right after the OCI VM has been created, log as opc user, then run:

sudo /usr/libexec/oci-growfs -y

To verify that the command ended properly, run:

$ lsblk

sda                  8:0    0   200G  0 disk

├─sda2               8:2    0     1G  0 part /boot

  └─ocivolume-oled 252:1    0    10G  0 lvm  /var/oled

Also:

$ df -h /
