Resizing existing attached volume

Linux Commands Ubuntu 16.04

I’ve followed this article in order to resize an attached volume’s size.
https://www.digitalocean.com/docs/volumes/how-to/increase-size/
After resizing it on DigitalOcean, I figured out that my volume’s partition is ext4. so according to the article, I’ve entered this command:

sudo resize2fs /dev/disk/by-id/scsi-0DO_Volume_volume-nyc3-02

The result is:

old_desc_blocks = 7, new_desc_blocks = 13
resize2fs: Permission denied to resize filesystem

What did I do wrong?

Thank you

Found the solution:

  1. First:

    fuser -cuk /mnt/volume-nyc3-02
    
  2. Then:

    e2fsck -f /dev/disk/by-id/scsi-0DO_Volume_volume-nyc3-02
    
  3. And then:

    resize2fs /dev/disk/by-id/scsi-0DO_Volume_volume-nyc3-02
    

Have fun!

If on Ubuntu:

To resize the partition, use the growpart command. In this command, /dev/vda is the name of the disk, separated by a space, and followed by the number of the partition to resize, 1.

growpart /dev/vda 1

For ext3/4 filesystems, use resize2fs to resize the filesystem.

resize2fs /dev/vda1

Check

df / -h
