- | ====== GlusterFS on maris ====== | ||
- | |||
- | We have configured a [[http:// | ||
- | with extra **3TB** of __scrap__ storage. | ||
- | |||
- | GlusterFS is a scalable network filesystem that can use common off-the-shelf hardware to create large, distributed storage solutions for media streaming, data analysis, and other data- and bandwidth-intensive tasks. | ||
- | |||
- | Currently, access to this file system is enabled only on '' | ||
- | |||
- | ===== Access GlusterFS ===== | ||
- | The maris GlusterFS is mounted under the ''/ | ||
- | |||
- | The mount-point name `maris-replicated-4x2' | ||
- | |||
- | ===== Distributed Replicated GlusterFS Volume ===== | ||
- | A `Volume' | ||
- | |||
- | The simplest GlusterFS configuration is the distributed volume configuration. Here, because files are distributed across various bricks in the volume, there is no data redundancy. | ||
- | |||
- | To add a degree of redundancy in case of disk(s) failure we opted to configure maris GlusterFS as a `distributed replicated volume' | ||
- | In this volume files are distributed across replicated sets of bricks. The number of bricks is a multiple of the replica count. Adjacent bricks become replicas of each other. This type of volume is used when high availability of data due to redundancy and scaling storage is required. In maris' case there are eight bricks and a replica count 2, so the first two bricks become replicas of each other then the next two and so on. This volume is denoted as 4x2. Hence the name give to the mountpoint. | ||
