Example scripts and configuration files to install and configure IBM Storage Scale in a Vagrant environment.
The scripts and configuration files provision a single node IBM Storage Scale cluster using Vagrant.
Open a Command Prompt and clone the GitHub repository:
git clone https://github.com/IBM/StorageScaleVagrant.gitcd StorageScaleVagrant
The creation of the Storage Scale cluster requires the Storage Scale self-extracting installation package. The developer edition can be downloaded from the Storage Scale home page.
Download the Storage_Scale_Developer-5.2.0.0-x86_64-Linux-install package and
save it to directory StorageScaleVagrant/software on the host.
Please note that in case the Storage Scale Developer version you downloaded is
newer than the one we listed here, you still might want to use the new
version. You need to update the $SpectrumScale_version variable in
Vagrantfile.common to match the version you
downloaded before continuing.
Vagrant will copy this file during the provisioning from the host to directory
/software on the management node m1.
Follow the Vagrant Getting Started Guide to install Vagrant to get familiar with Vagrant.
Storage Scale Vagrant supports the creation of a single node Storage Scale cluster on VirtualBox, libvirt and on AWS. There is a subdirectory for each supported provider. Follow the instructions in the subdirectory of your preferred provider to install and configure a virtual machine.
| Directory | Provider |
|---|---|
| aws | Amazon Web Services |
| virtualbox | VirtualBox |
| libvirt | libvirt (KVM/QEMU) |
Please note that for AWS you might want to prefer the new "Cloudkit" Storage Scale capability that is also available with the Storage Scale Developer Edition. For more details about Cloudkit, please refer to the documentation.
Once the virtual environment is provided, Storage Scale Vagrant uses the same
scripts to install and configure Storage Scale. Storage Scale Vagrant executes
those scripts automatically during the provisioning process (vagrant up) for
your preferred provider.
| Directory | Description |
|---|---|
| setup/install | Perform all steps to provision a Storage Scale cluster |
| setup/demo | Perform all steps to configure the Storage Scale for demo purposes |
Storage Scale Vagrant uses the Storage Scale CLI and the Storage Scale REST API to install and configure Storage Scale. In addition it configures the Storage Scale GUI to allow interested users to explore its capabilities.
Storage Scale Vagrant configures the shell $PATH variable and the sudo
secure_path to include the location of the Storage Scale executables.

To explore the Storage Scale REST API, enter
https://localhost:8888/ibm/api/explorer (for AWS please use https://>AWS Public IP>/ibm/api/explorer)
in a browser. The Storage Scale REST API uses the
same accounts as the Storage Scale GUI. There's also a blog post available which
contains more details on how to explore the REST API using the IBM API Explorer
URL:

Configuration of Storage Scale Cluster:
[vagrant@m1 ~]$ curl -k -X GET --header 'Accept: application/json' -u admin:admin001 'https://localhost:8888/scalemgmt/v2/cluster'
{
"cluster" : {
"clusterSummary" : {

}
},
.....

"message" : "The request finished successfully."
}
}

Cluster nodes:
[vagrant@m1 ~]$ curl -k -X GET --header 'Accept: application/json' -u admin:admin001 'https://localhost:8888/scalemgmt/v2/nodes'
{

To connect to the Storage Scale GUI, enter https://localhost:8888 (AWS:
https://<AWS Public IP>) in a browser. The GUI is configured with a
self-signed certificate. The login screen shows, after accepting the
certificate. The user admin has the default password admin001.
Cluster overview in Storage Scale GUI:
Storage Scale Vagrant configures the filesystem fs1 and adds some example data
to illustrate selected Storage Scale features.
The filesystem fs1 mounts on all cluster nodes at /ibm/fs1:
[vagrant@m1 ~]$ mmlsmount all
File system fs1 is mounted on 1 nodes.
[vagrant@m1 ~]$ mmlsfs fs1 -T
flag value description
------------------- ------------------------ -----------------------------------
-T /ibm/fs1 Default mount point
[vagrant@m1 ~]$
On Linux, a Storage Scale filesystem can be used like any other filesystem:
[vagrant@m1 ~]$ mount | grep /ibm/
fs1 on /ibm/fs1 type gpfs (rw,relatime,seclabel)
[vagrant@m1 ~]$ find /ibm/
/ibm/
/ibm/fs1
/ibm/fs1/.snapshots
[vagrant@m1 ~]$
REST API call to show all filesystems:
[vagrant@m1 ~]$ curl -k -s -S -X GET --header 'Accept: application/json' -u admin:admin001 'https://localhost/scalemgmt/v2/filesystems/'
{
"filesystems" : [ {
"name" : "fs1"
} ],
"status" : {
"code" : 200,
"message" : "The request finished successfully."
}
}[vagrant@m1 ~]$
Storage pools allow to integrate different media types such es NVMe, SSD and NL-SAS into a single filesystem. Each Storage Scale filesystem has at list the system pool which stores metadata (inodes) and optionally data (content of files).
[vagrant@m1 ~]$ mmlspool fs1

A typical configuration is to use NVMe or SSD for the system pool for metadata and hot files, and to add a second storage pool with NL-SAS for colder data.
[vagrant@m1 ~]$ cat /vagrant/files/spectrumscale/stanza-fs1-capacity
%nsd: device=/dev/sdg
nsd=nsd6
servers=m1
usage=dataOnly
failureGroup=1
pool=capacity
%nsd: device=/dev/sdh
nsd=nsd7
servers=m1
usage=dataOnly
failureGroup=1
pool=capacity
[vagrant@m1 ~]$ sudo mmadddisk fs1 -F /vagrant/files/spectrumscale/stanza-fs1-capacity
The following disks of fs1 will be formatted on node m1:
nsd6: size 10240 MB
nsd7: size 10240 MB
Extending Allocation Map
Creating Allocation Map for storage pool capacity
Flushing Allocation Map for storage pool capacity
Disks up to size 322.37 GB can be added to storage pool capacity.

Completed adding disks to file system fs1.

Now the filesystem has two storage pool.
