FS Mounts

The filesystem mount feature allows the automatic addition of NFS v3 or v4 volumes or mounts to virtual nodes/containers. This allows virtual nodes/containers to directly access NFS shares as if they were local directories. You can use this feature to provide common files across all of the virtual nodes/containers of a given tenant, such as a common configuration file that will be used by each of the virtual nodes/containers in the Marketing tenant. This eliminates the need to manually copy common files to individual virtual nodes/containers.

All virtual nodes/containers include a root directory called /bd-fs-mnt. If one or more filesystems have been mounted, then this directory will contain the mounted filesystems. Each mounted filesystem in this directory will have the same name as the Mount Name that was assigned when creating the FS mount (see Creating a New FS Mount).

Filesystems are mounted on a per-tenant basis, meaning that a given filesystem mount will be applied to each of the virtual nodes/containers in the tenant where that filesystem was created. For example, if you create a filesystem mount in the Marketing tenant, then each of the virtual nodes/containers created in the Marketing tenant will include that filesystem mount. Tenant Administrator users can create, modify, and delete filesystem mounts. Tenant Member and Platform Administrator users may view filesystem mounts but cannot modify them.

A filesystem may be mounted as either:

  • Read Only: Users can view (read) objects in the filesystem but cannot create, modify, or delete objects.
  • Read/Write: Users can view, create, modify, and/or delete objects.

FSmount is backed by a POSIX-based filesystem, such as the HPE Ezmeral Data Fabric POSIX client or NFS server. When HPE Ezmeral Runtime Enterprise is configured with HPE Ezmeral Data Fabric storage as its tenant storage, then FSmount points to HPE Ezmeral Data Fabric POSIX clients by default.

Inside every container:

  • When a new filesystem is mounted, the Name property will be populated in the /bd-fs-mnt directory.
  • The contents of the NFS share will be accessible in either read only or read/write fashion, depending on the settings provided when creating the mount.
  • Users will not be able to write files to or create new folders in /bd-fs-mnt.
