Global File System (GFS2)​

GFS2 is a shared file system designed to allow multiple Nodes to access a shared storage simultaneously.

This type of storage is commonly used in cluster environments where multiple Nodes need access to a shared storage space.

GFS2 is suitable for storage spaces that need to be available at the cluster level.

Local File System​

Local File System is used for storage located on the same Node or Server.

In this mode, the storage is placed on the local file system of the system and access to it depends on the same Node.

This type of storage is suitable for data that does not need to be shared between multiple Nodes.

Network File System (NFS)​

NFS is used to access shared storage through the network.

In this mode, the storage is located on an NFS Server and is made available to the system through the network.

This method is suitable for environments where a central storage is shared between multiple Nodes.

After selecting Network File System (NFS), the related connection and configuration fields are displayed.

Network File System NFS storage configuration

  • IP : Specifies the IP address of the NFS Server.

  • Source path : Specifies the mount path on the NFS Server.

  • Enable monitor : When enabled, the system attempts to re-establish the storage connection if it is disconnected.

  • Custom option : Allows entering custom options for mounting NFS.

  • Use NLM : On older NFS versions, enabling this option can help prevent potential file-locking related errors.

  • Retrans : Specifies the delay between retry attempts for connecting to the NFS Server.

  • Timeout (Seconds) : Specifies the waiting time for receiving a response from the NFS Server.

  • Port : Specifies the port used for connecting to the NFS service.

  • Retry : Specifies the number of retry attempts if the connection fails.

  • Protocol : Specifies the communication protocol used for connecting to the NFS Server.

Info

Port, protocol, and mount option values must match the NFS Server configuration.

Secure Shell File System (SSHFS)​

SSHFS allows connecting a remote file system through the SSH protocol.

In this method, files are accessed through an SSH connection.

This type of storage is commonly used for accessing storage available on a remote server.

After selecting Secure Shell File System (SSHFS), the remote server connection information must be entered.

Secure Shell File System SSHFS storage configuration

  • IP : Specifies the IP address of the SSH Server.

  • Port : Specifies the SSH service port.

  • Username : Specifies the username used for connecting to the SSH Server.

  • Password : Specifies the password of the user used for the connection.

  • Source : Specifies the required path on the remote server.

  • Enable monitor : When enabled, the system attempts to re-establish the storage connection if it is disconnected.

  • Nonempty : If this option is disabled and the destination path contains files, the mount operation will fail. When enabled, the system is allowed to remove the existing files from the destination path and then complete the mount operation.

Warning

If the Nonempty option is enabled, existing data in the Mount Point will be deleted. Make sure there is no required data in the path before enabling this option.

USB File System (USBFS)​

USB File System (USBFS) is used for storage connected through USB.

This type of storage can be used to access USB drives or other USB storage devices.

After selecting USB File System (USBFS), select the required USB device and partition.

Volume Group​

Volume Group is used for storage based on LVM (Logical Volume Manager).

In this mode, the storage uses an existing Volume Group in the system, and the required storage space is provided from that Volume Group.

Info

This storage type is available for iso and data content types.

Info

For more information about LVM, refer to the What is LVM?.

After selecting Volume Group in the Storage type field, the Volume group field is displayed.
