For unpartitioned volumes using the XFS filesystem, pass the mount point to the xfs_growfs tool:

sudo xfs_growfs /mnt/your_mount_point

Expand ext4 filesystems

For unpartitioned volumes using the ext4 filesystem, pass the /dev/disk/by-id volume identifier to resize2fs:

sudo resize2fs /dev/disk/by-id/scsi-0DO_example

The output will look like this:

resize2fs 1.42.13 (17-May-2015)
Filesystem at /dev/disk/by-id/scsi-0DO_example is mounted on /mnt/volume-example; on-line resizing required
old_desc_blocks = 25, new_desc_blocks = 32
The filesystem on /dev/disk/by-id/scsi-0DO_example is now 131072000 (4k) blocks long.

Note

If you receive the error open: No such file or directory while opening /dev/disk/by-id/scsi-0DO_example, ensure the volume is mounted and then retry the command.

Verify that the larger filesystem is available with df:

df -h -x tmpfs -x devtmpfs

Depending on the Droplet’s operating system, you may also need to reboot to see the volume’s new size.
