2.3.4 Object Store Filesystem (OSFS)
The OSFS is a userspace daemon on each host in the vSAN cluster, which:
• Provides a filesystem-like construct for compatibility.
• Is responsible for the creation of the vsanDatastore.
o There are no directories as such in vSAN. “Directories” in vSAN are actually objects formatted with VMFS.
• Handles the initial formatting of the “VM namespace” objects, mapping friendly names, and so on.
• Is responsible for mounting namespace objects and making them available in the vsanDatastore container.
