Add BrickGluster volume Add-brick Test-volume 10.100.15.111:/data2/test-volume 10.100.15.112:/data2/test-volumeAfter this is added, the client sees that the mounted disk is changed from 10G to 20G, but this time the client writes to the file. All the files are no longer written in the/data directory, but through the policy w

Glusterfs six volumes to explainFirst, the distribution volumeThe distributed volume file is randomly distributed across the entire brick volume. With distributed volumes, you need to extend storage, redundancy is important, or provide additional hardware/software layers. (Simplified: Distributed volumes, where files are randomly distributed through hash algorithms to volumes made up of bricks. The resources in the volume are stored only on one server

On multiple nodes after glusterfs is successfully installed, you can manage each node through the gluster Management Console. After successful addition, the public key can be automatically installed, however, if manual installation is required, you can configure the public key on each node according to the following steps. 1. First modify the/etc/hosts file to include the names and IP addresses of all nodes in the cluster; For example, 192.168.1.1

Filesystem in userspace (fuse) is a file system fully implemented in user mode. CurrentlySupport this through the kernel module. Some file systems such as ZFS, glusterfs, and moosefs use Fuse. The Linux kernel module used to support the user space file system is fuse. The term fuse is sometimes used to specify the user space File System in Linux. A file system is an important part of a general operating sys

. So it's not a test. In Ceph, a more advanced algorithm crush algorithm is used to design an upgradeable pseudo-random data distribution function for distributed object-based storage System, which can effectively manage data objects and storage devices without the need of a central directory. Since large systems are dynamic, crush is designed to be a convenient addition or removal of storage devices when unwanted data migrations are minimized. This algorithm provides a wide range of different t
