Description

Volumes under this category can be accessed from multi-hosts simultaneously.

Examples of this kind of shared storage are (either NFS based, or fuse based):

• NFS
• S3FS
• Glusterfs
• Portworx shared volume
• ...

The volumes in this category do not require multi-node coordination and does not need to be modeled as Resources (unlike those targeted in MESOS-8371). For instance, if a volume that can only be exclusively accessed from a node at any given time, then it does not qualify this category (e.g., EBS volume).

The support those those volumes will be much simpler (comparing to e.g., EBS volumes (MESOS-8371) which should be modeled as global resources) because Mesos can simply connect to those volumes as long as the framework has access to the handle of the volume, and all the lifecycle management of the volume can be done locally on an agent.
