Does Block Storage using ext4 support file locking?

I believe it’s up to the VFS to actually implement file locking. But I’d like to understand if there is any sort of file locking enabled on Block Storage using ext4?

Hi there,

Yes, I believe that this should be the case as the DigitalOcean Block Storage is essentially a block device, much like a physical hard drive. When you attach it to a Droplet and format it with ext4, it behaves like an ext4 filesystem would on any other block device.

So basically any feature of ext4, including file locking with flock, should be available.

Yes, flock should be available with ext4

When you automatically format and mount a volume, you also choose a filesystem. ext4 is the default because of its stability, backward compatibility, and mature support and tooling. XFS, which specializes in performance for large data files, is also available.

Hope this helps!
