Basic file system

This guide explains how to create and manage Basic file systems in File Storage.

Create file system

To create a Basic file system:

1. Go to KakaoCloud console > Beyond Storage Service > File Storage.

2. In the Basic file system menu, click the [Create file system] button.

3. Enter the required information and click the [Create] button.

   Category	Description
   File system information	Enter the name and description of the file system to create
   Protocol	Select a protocol for the server OS to mount - Currently, only NFS is supported - NFS can be used on Linux-based OSs such as Ubuntu and CentOS - File Storage uses NFS v4 and TCP port 2049
   Type	Select Basic - For details, see File system types
   Size	Set the file system size - Basic: 1.0 TB to 16 TB, in 0.5 TB increments - Example: 1.5 TB
   Network settings	VPC: Select the VPC for the file system Subnet: Select one subnet created in the selected VPC
   Access control settings	Set resources that can access the file system - Allow all private IP addresses: Resources in a reachable VPC can access without additional allow settings - Restrict to allowed private IP addresses: Allow only specified private IP addresses, up to 30 Note - If the VPC is shared with another project, resources in the other project can also mount the file system - If cross-subnet access is not supported, access is unavailable even if the IP address is allowed
   Mount information settings	Set the file share name to use as the mount point - Example: fileshare-01 - For names that cannot be used, see Unavailable shared directory names
