Installing Storage Gateway

1. Connect to your Compute instance or on-premises host.

   For help with connecting to an Oracle Cloud InfrastructureCompute instance, see Connecting to an Instance.

2. If your host volume is new, you might need to format and mount the disk.

   Tip
   
   

   This task describes the simplest way to create a functional file system to host a Storage Gateway. It uses one device and file system to host the cache, metadata, and log volumes. You specify the paths to those volumes later in this procedure. To optimize performance for your system, you can:

   • Create a separate device and file system for each of the cache, metadata, and log volumes.
   • Create a single device, but create logical volumes and file systems for the cache, metadata, and log volumes.

   To format the disk and create a file system:

   1. Run fdisk:

      sudo fdisk /dev/sdb

      (Optional) Press m to view the fdisk options.

   2. Choose command g - create a new empty GPT partition table.

   3. Choose command w - write table to disk and exit.

   4. Create an XFS (file system).

      To make file system volume extensive, we recommend using LVM to create logical partitions that can span across one or more physical hard drives. First, the hard drives are divided into physical volumes, then those physical volumes are combined to create the volume group and finally the logical volumes are created from volume group. Follow these steps:

      1. Create a volume group.

         sudo vgcreate <volume_group_name> <device>

      2. Create a logical volume.

         sudo lvcreate -l 100%FREE -n <logical_volume_name> <volume_group_name>

      3. Create an XFS file system.

         sudo mkfs.xfs /dev/<volume_group_name>/<logical_volume_name>

      4. Mount the XFS file system.

         sudo mount /dev/<volume_group_name>/<logical_volume_name> <directory_path>

   To mount the formatted volume:

   1. Create a mount directory:

      sudo mkdir /ocisg

   2. Mount the drive:

      sudo mount /dev/sdb /ocisg

3. Download the Storage Gateway 1.3 tar archive.
4. Use the SFTP tool of your choice to copy the tar archive into the /tmp folder of the host machine.

5. On the host machine, change directory to /tmp and extract the files from the tar archive:

   cd /tmp
   sudo tar xvzf ocisg-1.3.tar.gz

   This command extracts the files from the tar archive into a subdirectory named ocisg-1.3.

6. Change directory to ocisg-1.3 and run the installation script as sudo or root user:

   cd ocisg-1.3
   sudo ./ocisg-install.sh

   Optionally, you can specify the following ocisg-install.sh script flags:

   • -a Runs the installation in advanced configuration mode, which lets you specify ports and the Docker network mode.

     In addition to prompting you for the paths to the metadata storage, cache storage, and log storage, advanced configuration mode also prompts you for:

     • The Docker network mode (host or bridge).

       Bridge mode is the default. It allows multiple instances of Storage Gateway to run on the same host.

       Host mode improves network performance. If you plan to run only one instance of Storage Gateway on the host, Oracle recommends host mode. If you encounter issues with host mode, try bridge mode or contact My Oracle Support.

     • The host port to use for the management console.

     • The host port to use for NFS access.

     • The host port to use for the HTTP REST service.

       Tip
       
       For each host port specification, you can designate a port or press Enter to let Storage Gateway dynamically allocate the port. You can use the ocisg configure port command to change the ports later. See Managing Storage Gateway Using the CLI for details.

   • -d Installs Storage Gateway at the location you specify instead of the default location of /opt/ocisg. For example:

     sudo ./ocisg-install.sh -d /opt/storagegateway

     • -h Displays the installation script help information.

     • -p Specifies that Storage Gateway is running behind a proxy server. You can specify multiple proxy arguments. For example:

       ./ocisg-install.sh -p http://myproxy.com:80 -p https://mysecureproxy.com:80

     • -q Runs the installation in quiet mode.

       If you supply the paths to the Storage Gateway cache, metadata, and log storage locations using -m<path_to_metadata_storage>, -c<path_to_cache_storage>, and -l<path_to_log_storage>, you are not prompted for input. For example:

       sudo ./ocisg-install.sh -q -m /ocisg/metadata -c /ocisg/cache -l /ocisg/log

       Note
       
       Ignore the devicemapper warning message if it appears during the installation.

   The script guides you through the Storage Gateway installation. Depending on your host machine configuration, some steps can require your input:

   1. Docker does not appear to be installed. Do you want to install docker engine with yum? [y/N]

      Press y, and then press Enter.

      The installation script automatically installs Docker and configures the storage driver for use with Storage Gateway.

      Important
      
      

      If Docker is already installed on your system, the installation script does not automatically configure the storage driver and returns a warning message:

      Checking that docker is installed and using the correct version
      Found docker version Docker version 18.03.1-ol, build 0d51d18
      The storage appliance requires to set devicemapper as the docker storage driver.
      Please follow the setup link below to enable devicemapper and rerun the install.

      Manually verify and update the Docker storage driver to be devicemapper as required. See Verifying and Updating the Storage Driver in Docker.

   2. NFS server does not appear to be enabled. Do you want to enable NFS? [y/N]

      Press y, and then press Enter.

   3. When prompted, press Enter accept the default installation location.

   4. When prompted, specify the paths to your Storage Gateway cache, metadata, and log storage locations.

      The following examples represent paths for a simple system. Your setup might include paths to separate devices and file systems for each location.

      1. Enter a path for the file system cache. For example:

         /ocisg/sg/cache

      2. Enter the path for metadata storage. For example:

         /ocisg/sg/metadata

      3. Enter the path for log storage. For example:

         /ocisg/sg/log

      If you receive warnings about cache, metadata, and log storage existing on the same volume, enter y to proceed with the installation.

After a successful installation, the script provides the following information:

• The URL to log in to the Storage Gateway management console.
• The NFS port number.
• An example command for mounting your Storage Gateway file systems.

If you installed Storage Gateway on a Compute instance, see Security List Requirements for Compute Instance Installations.

1. Open the navigation menu. Under Core Infrastructure, go to Networking and click Virtual Cloud Networks.
2. Click the name of the cloud network (VCN) that hosts your Compute instance.
3. Click Security Lists.
4. Click the name of the security list that governs the subnet hosting your Compute instance.
5. Click Edit All Rules.

6. Add an ingress rule:

   1. Leave Stateless unmarked.
   2. Select CIDR for the Source Type.
   3. Enter 0.0.0.0/0 to indicate all IP addresses.
   4. Select TCP as the IP Protocol.
   5. Enter All in the Source Port Range field.

   6. Specify your Storage Gateway management console port in the Destination Port Range field. For example:

      32769

      If you do not know the management console port for your Storage Gateway installation, run the following command on the host machine:

      sudo ocisg info

      The management console port appears at the end of the management console URL:

      Management Console: https://exampleCompute:32769

7. Click Save Security List Rules.

   You can now connect to the compute instance using the public IP address (https:<public_IP_address>). See Getting the Instance Public IP Address and Initial Windows Password for details.
