Online Resizing of Block Volumes Using the Console
- Open the navigation menu and click Storage. Under Block Storage, click Block Volumes. In the Block Storage menu on the sidebar, click Boot Volumes. In the Boot Volumes list, click the boot volume you want to resize.
- Click Edit Size or Performance.
-
Specify the new size in VOLUME SIZE (IN GB). You must specify a larger value than the boot volume's current size.
-
Click Save Changes. This opens a dialog that lists the commands to rescan the disk that you need to run after the volume is provisioned. You need to run these commands so that the operating system identifies the expanded volume size. Click the Copy link to copy the commands, and then click Close to close the dialog.
-
Log on to your instance's OS and then paste and run the rescan commands you copied in the previous step into your instance session window. The rescan commands are also provided in Rescanning the Disk for Volumes Attached to Linux-Based Instances.
- Extend the partition and grow the file system using the oci-growfs operation from OCI Utilities.
