Question
Does Block Storage using ext4 support file locking?

Asked by Brett Bibby
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 anext4filesystem would on any other block device.So basically any feature of
ext4, including file locking withflock, should be available.Best,
Bobby
Heya,
Yes,
flockshould be available withext4When you automatically format and mount a volume, you also choose a filesystem.
ext4is 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!
