You can attach a block storage volume to only one Droplet at a time.

DigitalOcean volumes present as locally attached block devices. Attaching the same volume to multiple Droplets at the same time can corrupt data because the filesystems on each Droplet do not coordinate writes automatically.

If multiple Droplets need access to the same data, attach the volume to one Droplet and share the data over the network from that Droplet using one of these options:

• SSHFS for simple or lower-throughput access over SSH.
• NFS for shared access across multiple Droplets.

In this setup, one Droplet mounts the volume directly and the other Droplets access the files over the network instead of attaching the volume themselves.

Why does my Droplet show almost 100% disk usage even after attaching a new volume?

Attaching a volume adds separate storage and does not increase a Droplet’s root disk size.

Why is my resized volume smaller than I expected?

Filesystem overhead, reserved space, and unit conversions can make a resized volume appear smaller than its allocated size.
