Page 11: Chapter 1: Overview
Node Port Configurations SnapScale Conventions The SnapScale cluster supports three or more nodes hosting redundant sets of data for data protection. An Administrator can configure, add, or remove nodes on demand to change storage requirements. The overall storage system is able to easily grow from three nodes to meet your needs.
Page 12: Snapscale Node Requirements
Each peer set member has the same data and metadata as its peers. There are three different states for SnapScale nodes: • Uninitialized node – an independent node that has not yet been joined to a SnapScale cluster.
Page 13: Raincloudos Specifications
This is reported in the Web Management Interface. Common Storage network To form or join a SnapScale cluster, each Uninitialized node must be connected to the same Storage network as the other nodes. Storage network links To form or join a SnapScale cluster each Uninitialized node must have connectivity (active link) on both Storage network ports.

Page 85: Peer Sets
SnapScale aggregates all the storage on the peer sets in the cluster to form a unified data storage space for network client access. Data access is transparent between the cluster storage space and the peer sets so that users never directly access the peer sets.
Page 86: Peer Sets And Recovery
SnapScale/RAINcloudOS 4.1 Administrator’s Guide 5 – Storage Options Peer Sets and Recovery Though data on peer sets is served indirectly by the unified cluster storage space, access to files stored on a given peer set is dependent on the health of that peer set. When a drive in a peer set fails, data is served from the remaining peer set member drives.
Page 87: Peer Set Utilization
SnapScale automatically creates new peer sets and expand cluster storage space. Drives in a cluster do not all need to have the same capacity, but drives in a given peer set should have the same capacity or space is wasted on the larger drives.
Page 88: Peer Sets Page

IMPORTANT: Removing a node may result in one or more peer sets becoming degraded. These degraded peer sets may not be automatically repaired if there are not enough eligible spare drives on other nodes. Removing this node may also result in your SnapScale cluster operating with less than the minimum requirement of 3 nodes.
Page 135: Disks
Should a drive fail (solid red LED), it can be replaced (hot-swapped) without shutting down the SnapScale node. If a spare is available on a node that doesn’t already have an active member of the failed drive's peer set, the spare automatically replaces the failed drive and the new drive being installed automatically becomes a spare.
Page 136: Adding Drives
If there are no errors, after the new drive is incorporated, any alert LEDs are turned off and system statuses are updated. Adding Drives If new peer sets are created when adding new drives to a node in a SnapScale cluster, CAUTION: all existing snapshots will be deleted.

SnapScale/RAINcloudOS 4.1 Administrator’s Guide 8 - Maintenance Option Description Include All If the folder you select for import contains subfolders, selecting this Sub-folders option imports all files and folders underneath this folder (default is checked). NOTE: If disabled, only the files in this folder are imported.
Page 212: Preserving Permissions
If you are importing from a Unix server to a Unix personality directory, Unix permissions for UIDs/GIDs are copied exactly from source to target; thus, identities of the users and groups are best retained if the SnapScale cluster belongs to the same NIS domain as the Unix server. Importing Between Conflicting Security Models When importing from a Unix source to a Windows security model target, Unix permissions are retained and the security personality on the resulting files and directories will be Unix.

Page 215: Online/Rolling Updates Notes
The Online/Rolling Update option allows you to update the RAINcloudOS while leaving the SnapScale cluster online and active. Each node is upgraded and rebooted one at a time, and as a result, degrades the peer sets with members in that node during that process. After upgrade/reboot, each node rejoins the cluster and all peer sets are fully rebuilt before the rolling update proceeds to the next node.

• BitTorrent Sync installs as a hidden directory on a volume. If the volume is deleted or rolled back from a snapshot, the SnapScale attempts to automatically relocate the BitTorrent Sync hidden directory to another volume. If there are no more volumes, or if none can be found that are large enough, BitTorrent Sync is disabled and cannot be re- enabled until a suitable volume becomes available.

Page 244: Appendix A: Backup Solutions
Snap EDR provides server-to-server synchronization by moving, copying, or replicating the contents of a share from one cluster or server to another share on one or more different clusters or servers. It comes preinstalled on SnapScale clusters and activates a 45-day free trial if configured as a Management Console.
Page 245: Snap Edr Usage
Console running on the server, or other Agents replicating to/from the server) need to be able to resolve the SnapScale cluster name to its IP address in order to interoperate properly with the cluster. This can be accomplished via a DNS host record, local hosts file entries, or other name resolution services in the environment.
Page 246: Scheduling Jobs In Snap Edr
A SnapScale can be backed up using a third-party Linux agent or media server installed on one cluster node. A tape drive or library can be attached to the node to provide local backup of the cluster.
Page 247: Appendix B: Security And Access
Appendix B This appendix provides additional information and configuration options about securing and accessing shares and files on the SnapScale. The RAINcloudOS supports share-, file-, and directory-level permissions for all local and Windows domain users and groups. File and directory security can be configured using either Windows NTFS-style security or classic Unix-style security.
Page 248: Security Model Management
Special Share Options The basic setup and configuration of shares on a SnapScale cluster is handled on the Security > Shares page.
Page 249: Hiding Shares
For security and backup purposes, it is recommended that administrators restrict access to shares at the root of a volume to administrators only. After initialization, all SnapScale clusters have a default share named SHARE1 that points to the root of the default volume Volume1.
Page 250: Nfs Share Access
A snapshot share is a read-only copy of a live share that provides users with direct access to versions of their files archived locally on the SnapScale cluster via a snapshot. Users who wish to view or recover an earlier version of a file can retrieve it on demand without administrator intervention.
Page 251: File-Level Security
SnapScale/RAINcloudOS 4.1 Administrator’s Guide B - Security and Access For example, assume the snapshot share named Sales_SNAP contains the following four directories: latest 2014-02-25.120000 2014-03-01.000100 2014-03-07.020200 The latest directory always points to the most recent snapshot (in this case, 2014-03- , or March 7th, 2014, at 2:02 a.m.).

You Have No Access to SnapScale via HTTP When trying to access the SnapScale via HTTP, the Web browser times out. However, the cluster can be accessed using the ping command or Windows Explorer. • HTTP and HTTPS are both enabled by default. Try typing HTTPS in the Web address rather than HTTP.
Page 258 Ensure that the Ethernet cable is connected securely to both the network port and the primary Ethernet port. Also, check to see that the Link light on the front of the SnapScale is lit (solid green). If the Link light is off, this is normally caused by a mismatch between the switch/hub and the Ethernet port on the SnapScale.
