NOTE: Deleting a NAS container deletes all the snapshots of the NAS container and all the SMB shares and NFS exports in the NAS container. After they are deleted, recovery containers cannot be recovered using the volume recovery bin. When you delete a NAS container, its replica is not deleted; the replica is promoted to a container on the destination cluster. To delete a NAS container: 1. Click NAS, expand NAS Clusters and Local Containers, and then select the NAS container name. 2. Click Delete container. NOTE: You must disable the SMB home shares before you can delete a NAS container that has SMB home shares defined in it. 3. Click Destroy size data, where size is the size of the NAS container that you want to delete. You must select this checkbox to delete the container. 4. Click Yes. NFS Netgroups An NFS (Network File System) export provides an effective way of sharing files and data across networks. FluidFS provides support for the SMB and NFS protocols. NFS is the network file-sharing protocol that is associated with the Linux and UNIX operating systems. An NFS export can be accessed by using NFS v3 or NFS v4. When specifying restrictions for NFS, you can apply the following settings: • A single IP address • An IP network • A netgroup • No restrictions You can configure netgroups and set restrictions so that only specific netgroups can access an NFS export. Of the three fields in the netgroup form (host, user, domain), FluidFS supports only the host field. You can configure the netgroups host field with one of the following items: • A single IP address • A host name NOTE: Group Manager supports host netgroup (host name or IP address) only. User netgroup, domain netgroup, and subnet in host netgroup are not supported at this time. Network file sharing works with access protocols in the following ways: • Homogeneous - All file sharing is done through a single protocol, as in a Windows-only file-sharing environment. • Heterogeneous - Both SMB and NFS clients access files and directories. NOTE: • To use the NFS protocol, UDP traffic on port 2049 must be allowed between a client and the NAS cluster. • Any files or directories stored in a FluidFS NAS volume includes metadata that saves access permissions to the file or directory. Access NFS Exports NFS version 3 relies on client authentication services. If a user can authenticate to a client machine, they can use the NFS mount command to access a FluidFS export. During an NFS export session, each operation is verified using the user's UID (user ID) and GID (group ID). FluidFS queries the configured directory services to obtain the group membership of the UID provided. NFS version 4 uses Kerberos authentication services. Initially, only a root user can access an NFS export. To set the ownership and permissions for the share: 186 NAS Container Operations
