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
dened 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 eective way of sharing les and data across networks. FluidFS provides support
for the SMB and NFS protocols. NFS is the network le-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 congure netgroups and set restrictions so that only specic netgroups can access an NFS export. Of the three elds in the
netgroup form (host, user, domain), FluidFS supports only the host eld.
You can congure the netgroups host eld 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 le sharing works with access protocols in the following ways:
• Homogeneous – All le sharing is done through a single protocol, as in a Windows-only le-sharing environment.
• Heterogeneous – Both SMB and NFS clients access les and directories.
NOTE:
• To use the NFS protocol, UDP trac on port 2049 must be allowed between a client and the NAS cluster.
• Any les or directories stored in a FluidFS NAS volume includes metadata that saves access permissions to the le 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 veried using the user’s UID (user ID) and
GID (group ID). FluidFS queries the congured 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:
