post /v9/storage/filesystems/{filesystemId}/unassign

Removes a filesystem from a virtual server. The filesystem must be unmounted to remove the assignment. Once the filesystem is unassigned, it can no longer be mounted, until it is reassigned to a virtual server. If the file system is currently participating in a data migration path, removing it from a virtual server may result in unexpected loss of data. The ignoreMigrationPaths option will enable the unassignment to proceed, despite the risks.

Note: Accepted parameter values may be restricted based on the virtual server access granted by the API key used for authentication.

Authentication: x_subsystem_user Api Key "X-Subsystem-User"

Authentication: x_subsystem_password Api Key "X-Subsystem-Password"

Authentication: api_key Api Key "X-Api-Key"

Authentication: basicAuth HTTP - basic scheme

Path parameters

filesystemId String required

Either the file system ID or the object ID of the file system
