Enable or Disable the NAS Pool Unused Space Alert
You can enable or disable an alert that is triggered when the remaining unused NAS pool space is below a specified size.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the Summary tab.
3. In the Summary panel, click Edit NAS Pool Settings.
The Set NAS Pool Space Settings dialog box opens.
4. Enable or disable the NAS pool unused space alert:
● To enable the NAS pool used space alert, select the Unused Space Alert checkbox.
● To disable the NAS pool used space alert, clear the Unused Space Alert checkbox.
5. If the Unused Space Alert checkbox is enabled, in the Unused Space Threshold field, type a number (from 0 to 100) to
specify the percentage of unused NAS pool space that triggers an alert.
6. Click OK.
About Multitenancy
Multitenancy enables a single physical FluidFS cluster to be partitioned into several separate service entities (tenants) and
manage each one individually. FluidFS supports up to 100 tenants. When multitenancy is enabled, the user interface is optimized
and includes the tenants view.
Network connections – Each tenant utilizes exclusive IP addresses (virtual IPs). Users who have access to the tenant’s VIP
can only see that tenant’s NFS exports, SMB shares, and so on.
Authentication and user repositories – Each tenant utilizes its own authentication and user repositories. Each tenant can
define and use the following settings:
● DNS configuration – The DNS configuration of the default tenant serves the cluster services (such as NTP).
● Active Directory – Each tenant can join a different Active Directory. Two tenants can also join the same Active Directory
(with separate tenant computer objects in Active Directory).
● LDAP or NIS
● Local users and groups
● User mapping
Reusing of same name in different tenants – Multitenancy supports using the same SMB share name and the same local
user or group name.
Volume Replication – Administrators can define between which tenants volume replication is allowed.
Managing tenants – FluidFS v6 added a new type of administrator called tenant administrators. A tenant administrator has the
ability to:
● See (but not update) all of the general cluster settings
● Manage tenants they have been granted Tenant Administrator access to, including all the NAS volumes that belong to those
tenants
● Receive email events that are relevant to the entire cluster and to the tenants they have been granted Tenant Administrator
access to, such as power-down events
Using Multitenancy With Existing Features
Multitenancy interoperates with the following existing FluidFS features:
Antivirus – SMB shares are isolated to their tenant. If any shares have antivirus enabled, they utilize the virus scanners that are
defined at the clusterwide level.
File Access Notifications – File access notifications are set at a clusterwide level in FluidFS. If multitenancy is in use,
only one tenant can utilize the external audit server feature. Separation of file access notifications between different tenants
requires multiple FluidFS clusters. Alternatively, you can use SACL auditing, which is separated between tenants for file access
notifications.
NDMP Backup – You can back up any of the volumes using any of the VIPs (or physical controller IPs), regardless of
multitenancy. Separation of NDMP between different tenants requires multiple FluidFS clusters.
