Introduction
Scalable File System is designed to provide simple, scalable, and highly available file storage for cloud-based applications and services. It allows multiple E2E Nodes to access the same file system concurrently, enabling shared file storage across instances.
The Scalable File System is commonly used for applications that require shared file storage, such as content management systems, web serving, big data analytics, and development environments. It simplifies the management and provisioning of file storage in the cloud, allowing applications to scale seamlessly and reliably.
Create Scalable File System
If you want to create a Scalable File System, just go to the left sidebar under the dashboard section, then go to Storage -> Scalable File System.
Then click on the Create button to create a Scalable File System.
After clicking on Create Scalable File System, give a name to your SFS, select the plan and VPC, and then click on the Create SFS button.
After clicking on the Create SFS button, your created Scalable File System will be shown like this.
Activate Backup
You can click Activate Backup under Actions for a particular SFS.
The Activate Backup popup will open. You can select a particular backup time and click on the Activate button.
After activating the backup, the backup status will be First run pending.
Once the backup service is enabled and the status changes from First Run Pending to Backup Available, you can see the backup details under the Backup tab.
Deactivate Backup
After successfully activating the backup, you can deactivate the backup by clicking Deactivate Backup under Actions.
After that, a pop-up will appear. If you click on the Deactivate button, the backup will be deactivated successfully.
Grant all access
If you will grant all access, you will not be able to configure ACL. To configure ACL you have to disable all access.
To grant all access, select a particular SFS (Scalable File System) and click on Grant All Access under Actions.
After clicking the Grant All Access action, you will see the popup below. If you click on the Grant button, it will grant full access, enabling all resources like Nodes, Load Balancers (LB), Kubernetes, and DBaaS within the same VPC to access this SFS.
The permission has been granted, and the process has started. It should be completed within a few minutes. You can view the configured Virtual Private Cloud (VPC) under the ACL tab.
Disable All Access
If you disable all access, it will deny full access to all resources such as Nodes, Load Balancers, Kubernetes, and DBaaS within the same VPC from accessing this SFS.
If you want to disable all access from SFS (Scalable File System), click on Disable All Access under Actions.
After clicking Disable All Access, you will see the popup below. If you click the Disable button, access will be disabled from all services.
The disable access process has started. It should be completed within a few minutes. You can view the configured Virtual Private Cloud (VPC) under the ACL tab.
Delete SFS
ACL
Using ACL configuration, you can give permission to allow a Node to access the SFS. To configure ACL, go to the ACL tab and click on Configure ACL.
After clicking on Configure ACL, the nodes attached to the same VPC network will be shown. Select the permissions according to your requirement and click on the Allow button to attach the Node to SFS.
After clicking the Allow button, the node will go into Configuring status, and after some time, it will return to Available status.
How to Access Scalable File System (SFS)?
You need to connect your machine and follow these commands to mount the SFS.
1) For YUM Package Manager
Step 1: Install nfs-utils on your machine using the yum package installer.
yum update
yum install nfs-utils
Step 2: Make a MOUNT_POINT
mkdir MOUNT_POINT
Step 3: Mount SFS on your machine.
mount -t nfs -o soft,timeo=n, retrans=n, retry=n, SFS_SERVER_ENDPOINT:/data MOUNT_POINT
soft - When NFS tries to access a soft-mounted directory, it gives up and returns an error message after trying retrans times.
timeo - The timeout, in tenths of a second, for requests (read and write requests to mounted directories). If a request times out, this timeout value is doubled, and the request is retransmitted. Maximum value is 30 seconds, and the default value is 7 seconds.
retrans - The number of times a request (a read or write request to a mounted directory) is retransmitted after it times out. If the request does not succeed after n retransmissions, a soft mount returns an error. The default value is 4.
retry - The number of times the client attempts to mount a directory after the first attempt fails. The default value is 1.
2) For APT Package Manager
Step 1: Install nfs-common on your machine using the APT package installer.
sudo apt update
sudo apt install nfs-common
Step 2: Make a MOUNT_POINT
mkdir MOUNT_POINT
Step 3: Mount SFS on your machine.
mount -t nfs -o soft,timeo=n, retrans=n, retry=n, SFS_SERVER_ENDPOINT:/data MOUNT_POINT
soft - When NFS tries to access a soft-mounted directory, it gives up and returns an error message after trying retrans times.
timeo - The timeout, in tenths of a second, for requests (read and write requests to mounted directories). If a request times out, this timeout value is doubled, and the request is retransmitted. Maximum value is 30 seconds, and the default value is 7 seconds.
retrans - The number of times a request (a read or write request to a mounted directory) is retransmitted after it times out. If the request does not succeed after n retransmissions, a soft mount returns an error. Default value is 4.
retry - The number of times the client attempts to mount a directory after the first attempt fails. Default value is 1.
3) For Windows Machine
Step 1: Make sure you have an NFS Client (Services for NFS) installed from Programs and Features.
Step 2: Mount SFS to a drive.
mount -t nfs -o soft,timeo=n, retrans=n, retry=n, SFS_SERVER_ENDPOINT:/data drive:
soft - When NFS tries to access a soft-mounted directory, it gives up and returns an error message after trying retrans times.
timeo - The timeout, in tenths of a second, for requests (read and write requests to mounted directories). If a request times out, this timeout value is doubled, and the request is retransmitted. Maximum value is 30 sec and the default value is 7 sec.
retrans - The number of times a request (a read or write request to a mounted directory) is retransmitted after it times out. If the request does not succeed after n retransmissions, a soft mount returns an error. Default value is 4.
retry - The number of times the client attempts to mount a directory after the first attempt fails. Default value is 1.
