Installing and Configuring napp-it and OpenIndiana
This article is the first in a multi- part series featuring napp-it. For those that do not know what napp-it is, it is a free NAS / SAN web interface for Solaris derivatives. That is a big deal because it takes one of the most robust file systems in ZFS and makes it easy to use. Solaris and OpenSolaris derivatives such as OpenIndiana may not have the press that they once did, but it is built to be an ultra reliable operating system. ZFS has tons of great features built-in for data protection, memory caching, SSD caching, software RAID and etc. Prior to napp-it, managing a ZFS NAS based on Solaris or OpenSolaris meant learning CLI commands. With napp-it, users have an easy way to manage their ZFS NAS / SAN. Today we will be covering the installation and general configuration of napp-it and OpenIndiana as a Network Attached Storage (NAS) device, and creating and accessing a storage pool.
Napp-it running on top of OpenIndiana allows you to share your files utilizing the FTP, CIFS/SMB (Windows Shares), AFP, NFS, rsync, iSCSI, and FOE protocols It can make a great addition to your home, small business, or office network as a robust storage solution, while being easily managed through the use of a web browser interface. We will be using the Desktop version of OpenIndiana. More advanced users may choose to use the server version without the Gnome Desktop Environment. This article will be universal for both Desktop and Server versions. OpenIndiana is binary compatible with Solaris 11 and Solaris 11 Express. For more information check out OpenIndiana’s documentation. OpenIndiana has a great Wiki and FAQ, as well as excellent installation instructions.
Key Features of OpenIndiana and napp-it and their System Requirements
Before we begin, let’s look at a few of the key features of both OpenIndiana and napp-it:
Key Features of OpenIndiana
- ZFS File system
- COMSTAR SCSI Target System supporting iSCSI, iSER, FCOE and FC
- IP Multipathing
- Integrated Layer 3 and Layer 4 Load Balancer
- Crossbow high performance network stack
- Solaris-derived OS
Key Features of napp-it
Napp-it is a web browser managed, free internet NAS, SAN and Backup Server, and much more. The web interface is both intuitive, and easy to use. This makes managing your storage very simple without having to learn the host operating system’s command line interface.
- ZFS Management of disks, pools, and RAID-Z, RAID-Z2 and RAID-Z3 pools within a few mouse clicks
- Single command installation
- Simple and easy user and folder management
- Simple and easy folder and share management
- Easily configured to work with VMware ESXi and other hypervisors as a SAN storage solution
- Works great with Windows as a networked file server and or iSCSI storage target, even supports Active Directory Users and Groups
- AFP File server supporting Time Machine for your Mac
Suggested Minimum Requirements:
(You can get away with less, but you will not be happy)
- Dual core 64bit CPU.
- A minimum of 4 GB of RAM, ZFS likes memory, the more the merrier! (I have 16 GB of RAM in my napp-it server and ZFS can use a LOT of RAM)
- 20 GB boot disk (DO NOT USE A USB DRIVE) and at least 2 additional hard disks for datapools.
- A Network Interface card, two or more are recommended for iSCSI and or NFS storage services.
Your mileage may very with less than 8 GB of RAM. The ZFS file system will use as much available memory as possible as cache to enhance efficiency. It is not unusual for ZFS to consume the majority of all of the available RAM. CPU utilization can be intensive as well. While a single core processor may be enough in some cases, I notice that it is not unusual during large transfers and benchmarks for my CPU to utilize all four cores fairly heavily.
Now it’s time to get down to the nitty gritty. Installing OpenIndiana, and setting up your napp-it NAS.
- Download and burn a copy of OpenIndiana Live to a DVD.
- Boot from the OpenIndiana Live DVD, select all the defaults for English and change as necessary.
- OpenIndiana will then automatically go to a Live Desktop, select “Install OpenIndiana”, this will start the installation wizard. It will then ask you a series of questions such as which disk to install to, time zone information, a root password, a user account, and a computer name. After reboot, log on to OpenIndiana with the User Account you created during the installation wizard.
Preparing OpenIndiana for the Installation of napp-it
We now need to change the root password as well as the auto-magic network settings to a static IP address. We will do this by entering the console as root.
Changing the root password:
You will first need to change the root password, to do so Launch a Terminal Session, this the command line shell for Openindiana, and type: su
You will receive a message “Password for user ‘root’ has expired” then prompted with “New Password:” and “Re-enter Password” the second time. You will receive a message that the password successfully changed for root.
Configuring the NIC:
- Type svcadm disable nwam then type svcadm enable network/physical:default
- We need to check the state of the NIC as well as its name . Type dladm show-phys
You should see something like this returned:
LINK MEDIA STATE SPEED DUPLEX DEVICE
e1000g0 Ethernet unknown 1000 full e1000g0
- We will now create a new network connection, type ipadm create-if e1000g0 where “e1000g0″ is my device name, then assign a static IP address for the NIC by typing ipadm create-addr -T static -a 192.168.1.199 e1000g0/v4 (Make sure you are using an unused IP address!) We now need to create a static route, and default gateway. This is typically your router or cable modem IP address. Type route -p add default 192.168.1.1 Make sure that you input YOUR gateway IP addres, not mine.
- We will now look at our resolv.conf file. Type cat /etc/resolv.conf and verify that your name server is also the default gateway, this applies to most home users on a peer to peer network, otherwise it will be your DNS server.
- We will now replace the nsswitch.conf with nsswitch.dns. Backup nsswitch.conf by typing mv /etc/nsswitch.conf /etc/nsswitch.backup then replace it with the following command cp /etc/nsswitch.dns /etc/nsswitch.conf
- Verify that you have internet connectivity by typing dig www.yahoo.com this should return the name servers for yahoo.com.
- While still in the console enter the command reboot to reboot the machine.
Installing napp-it is a single command operation performed from a Terminal Session as root.
- Simply launch a Terminal in Openindiana, then type su
- Next, we will launch the installer command: wget -O – www.napp-it.org/nappit | perl
- Now you can sit back and watch the magic.
When the installer has completed, reboot.
Basic Configuration of napp-it
In this portion of the setup, we are going to change the admin and operator passwords, create a user, create a pool of disks, and a shared folder.
Log on to napp-it the first time with your web browser pointed to the IP address on port 81, in my case it is http://192.168.1.199:81 where you will be presented a Login Screen.
Take note that there currently are no passwords set for the admin or the operator accounts, you will be prompted to create them upon pressing the login button.
In this example, we will only be changing the admin-pw and operator-pw fields.
Upon pressing the submit button, you will then be returned to the Login screen.
We now need to initialize our disks that will be used to create a new Storage Pool. WARNING! This will destroy all the data on the disks. Keep this in mind before you initialize them.
From the top menu, mouse over Disks and select Initialize where you will be presented with the initialize disk page.
You will note that I have three disks that are not part of a pool, each disk that will be used in a pool will need to be initialized. Select each disk you wish to add to a new pool, one at a time, from the Select disk to initialize drop down menu, then select the initialize and re-partition disk button.
Here we are going to create a basic storage pool running RAIDZ1. We have our newly initialized disks and it is time to put them to use.
From the top menu, mouse over to Pools and select Create Pool. Input a name for your pool, from the drop down for type of first vdev select raidz and select submit.
We now need to create a ZFS Folder. Mouse over ZFS Filesystems and select Create. Verify that the newly created pool is selected from the pool drop down menu. Create a name in the name of new zfs-folder/ filesystem field, in my case I am creating a folder called data, and then press submit.
We are now ready to configure sharing. We will be setting the Workgroup name, enabling the SMB/CIFS Server and SMB/CIFS Client services.
- From the top menu, mouse over Services, SMB and select Workgroup. You will be presented with the SMB/CIFS Service screen, in the name of workgroup ex home field, input your workgroup name and press the submit button.
- From the top menu, mouse over Services and select SMB. From this SMB/CIFS Service screen, enable both the SMB/CIFS Server and SMB/CIFS Client services by setting both dropdown menus to online then submit button.
To access your share, open Windows Explorer and input \\openindiana\data where openindiana is the name of the napp-it server.
Congratulations! You have successfully setup napp-it running on OpenIndiana.
