Create a volume

You can create a volume and specify its junction point and other properties by using the volume create command.

About this task

A volume must include a junction path for its data to be made available to clients. You can specify the junction path when you create a new volume. If you create a volume without specifying a junction path, you must mount the volume in the SVM namespace using the volume mount command.

Before you begin

  • The SVM for the new volume and the aggregate that will supply the storage to the volume must already exist.

  • If the SVM has a list of associated aggregates, the aggregate must be included in the list.

  • Beginning in ONTAP 9.13.1, you can create volumes with capacity analytics and Activity Tracking enabled. To enable capacity or Activity Tracking, issue the volume create command with -analytics-state or -activity-tracking-state set to on.

    To learn more about capacity analytics and Activity Tracking, see Enable File System Analytics.

Steps

  1. Create a volume:

    volume create -vserver svm_name -volume volume_name -aggregate aggregate_name -size {integer[KB|MB|GB|TB|PB]} -security-style {ntfs|unix|mixed} -user user_name_or_number -group group_name_or_number -junction-path junction_path [-policy export_policy_name]

    The -security style, -user, -group, -junction-path, and -policy options are for NAS namespaces only.

    The choices for -junction-path are the following:

    • Directly under root, for example, /new_vol

      You can create a new volume and specify that it be mounted directly to the SVM root volume.

    • Under an existing directory, for example, /existing_dir/new_vol

      You can create a new volume and specify that it be mounted to an existing volume (in an existing hierarchy), expressed as a directory.

    If you want to create a volume in a new directory (in a new hierarchy under a new volume), for example, /new_dir/new_vol, then you must first create a new parent volume that is junctioned to the SVM root volume. You would then create the new child volume in the junction path of the new parent volume (new directory).

  2. Verify that the volume was created with the desired junction point:

    volume show -vserver svm_name -volume volume_name -junction

Examples

The following command creates a new volume named users1 on the SVM vs1.example.com and the aggregate aggr1. The new volume is made available at /users. The volume is 750 GB in size, and its volume guarantee is of type volume (by default).

cluster1::> volume create -vserver vs1.example.com -volume users1 -aggregate aggr1 -size 750g -junction-path /users
[Job 1642] Job succeeded: Successful

cluster1::> volume show -vserver vs1.example.com -volume users1 -junction
                          Junction                 Junction
Vserver           Volume  Active   Junction Path   Path Source
----------------- ------- -------- --------------- -----------
vs1.example.com   users1  true     /users          RW_volume

The following command creates a new volume named “home4” on the SVM"`vs1.example.com`" and the aggregate “aggr1”. The directory /eng/ already exists in the namespace for the vs1 SVM, and the new volume is made available at /eng/home, which becomes the home directory for the /eng/ namespace. The volume is 750 GB in size, and its volume guarantee is of type volume (by default).

cluster1::> volume create -vserver vs1.example.com -volume home4 -aggregate aggr1 -size 750g -junction-path /eng/home
[Job 1642] Job succeeded: Successful

cluster1::> volume show -vserver vs1.example.com -volume home4 -junction
                         Junction                 Junction
Vserver          Volume  Active   Junction Path   Path Source
---------------- ------- -------- --------------- -----------
vs1.example.com  home4   true     /eng/home       RW_volume
