Resizing existing attached volume
I've followed this article in order to resize an attached volume's 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?
