Releasing nodes from file storage

Limitations

When the last node in the file storage cluster is removed, the cluster is destroyed and all of the data is deleted.

Prerequisites

The file storage cluster is created, as described in Creating the file storage cluster.
If a node hosts shares, you need to delete all of them first before releasing the node.

To release a node from file storage

Admin panel

Command-line interface

Use the following command:

vinfra service file-storage node remove <node> [<node> ...]

For example, to release the node node002 from the file storage cluster, run:

# vinfra service file-storage node remove node002

To destroy file storage

Admin panel

Go to the Storage services > File storage > Nodes screen.
Select all nodes in the cluster, and then click Release above the node list.
In the confirmation window, enter your Active Directory credentials and click Release.

Command-line interface

Use the following command:

vinfra  service file-storage cluster delete [--krb-username <username>] [--krb-password] [--krb-ticket <ticket>] [--force]

--krb-username <username>: Kerberos username
--krb-password: Request the Kerberos password from stdin. Alternatively, the password can be set via the MPFS_KRB_PASSWORD environment variable.
--krb-ticket <ticket>: Path to the Kerberos ticket
--force: Forcefully unjoin cluster from Active Directory domain

For example, to release the last node and destroy the file storage cluster, run:

# vinfra service file-storage cluster delete --krb-username administrator --krb-password
Kerberos password [administrator]:

Specify the user password when prompted.
