Gluster 3.1: Displaying Volume Properties
From GlusterDocumentation
You can display the volume properties, including the volume name, volume type, transport type, storage servers, exports, authentication information, and volume status.
Fields
The following table describes the information displayed when viewing the volume properties:
| Volume name
| The name of the volume.
|
| Volume type
| The type of the volume, from among the following:
- Plain Distribute - Creates a volume that is not mirrored or striped
- Distributed Mirror - Creates a mirrored volume. All files are replicated twice. Note that you need at least two servers to activate this feature.
- Distributed Stripe - Creates a striped volume. Each file is spread across four servers to share the load during file access. Note that striping typically increases performance only in High Performance Computing (HPC)/Supercomputing environments where hundreds or thousands of clients access a single large file (typically much larger than the server's memory). You need a minimum of four servers is to activate this feature.
|
| Transport type
| The type of the transport, from among the following:
|
| Storage servers
| Select the servers that comprises the volume.
|
| Exported as
| The file systems through which the volume can be accessed, including the following:
- GlusterFS Native - Designed for scalability and performance, GlusterFS Native is both intelligent and efficient in file access and is fully POSIX compliant so no modification to the application code is required. However, GlusterFS Native only works on FUSE-capable kernels such as Linux. A small userspace GlusterFS client needs to be installed on the system in order to natively mount volumes.
- NFS - Distributed NFSv3 TCP support offers scalability without imposing additional software requirements on the client. Most Unix and GNU/Linux operating systems support the NFSv3 TCP protocol.
- CIFS - Ideal for general-purpose file storage and archival in Windows environments (Microsoft operating systems have built-in CIFS client support).
- WebDAV - A standards-based, distributed, object storage mechanism using HTTP as the underlying transport.
|
| Authentication Type IP-Based
| The IP addresses of clients that can access the volume, specified as a comma-separated list (with wildcards). An asterisk (*) specifies all IP addresses.
|
| Volume status
| The current status of the volume.
|
