Creation of TRS instance¶

In the general list of all instances on the control panel, open the creation wizard using “Launch TRS instance” button:

TRS instance creating window¶

In the window that opens, indicate:

• TRS project, selection of the required project. This field is required;
• Number of instances is the number of instances to start. It is possible only within limits of available resources. This field is required;
• “I confirm, that I am not using a clustered file system” is enabling or disabling confirmation that a clustered file system is not used. Without confirmation, only one TRS instance can be started;
• Instance name is optional field; if value is empty, the name is generated automatically;
• Description is description of the TRS instance. The field is optional;
• Instance users, managing TRS instance users within the selected project. For user without administrator rights, assignment is possible only on instances of available projects;
• Instance groups, management of TRS instance groups within the selected project. Function is available only for the administrator;
• Volumes, attach volumes to TRS instance. When starting several instances at once, tab is not displayed, since it is impossible to connect volumes to several TRS instances at same time.

Follow instructions on pages of the wizard to select the options that are appropriate for the operating system of instance. We complete creation procedure with “Save” button. After that, correctly created instance will be displayed in the general list. Otherwise, the system will return you to the wizard window indicating reasons for the impossibility of its creation.

After the successful creation procedure is completed, the instance may take time to finalize all systems. Ultimately, the instance is displayed with the status “Active”. When a TRS instance is created, security group associated with it is automatically created.

Creation of TRS instance with placement in permanent storage system¶

Cinder is used as a backend for bootable disks.

To create a TRS instance with placement in a permanent storage system, you need to do the following:

1. For the instance running from volume, take a snapshot (in the “Project” or “Administrator” section):

If “Full cloning” option is checked, possibility of editing TRS instance clone will disappear, full clone of the original TRS instance will be created by creating snapshot and starting the instance from created snapshot. Then snapshot is deleted automatically. Full clone of instance will also clone all the instance’s tags, metadata, attached volumes, assigned users and groups. Default name is “Full clone of <name of the cloned machine>”.
