ceph storage cluster

This is a creation in Article, where the information may have evolved or changed. All the places involved in storage are very prone to "pits", Kubernetes is no exception. First, the cause of the problem The problem began yesterday by upgrading the operation of a stateful service. The pod under the service is mounted with a persistent Volume provided with Ceph RBD. The pod is deployed with normal deployment

As Ceph is increasingly used in various storage business processes, its performance and tuning strategy has become a topic for users to pay close attention to, one of the key factors affecting performance is the OSD storage engine implementation; The Ceph base component Rados is a strong consistent, object

Owncloud Introduction:is a free software developed from the KDE community that provides private WEB services. Current key features include file management (built-in file sharing), music, calendars, contacts, and more, which can be run on PCs and servers.Simply put is a PHP-based self-built network disk. Basically private use this, because until now the development version has not exposed the registration function. I use the php7.1-based lamp environment to build this owncloud next article will i

Server Load balancer is a difficult task. We often need to provide a central address for data through NFS (Network File System) or other mechanisms to share the file system. Although your security mechanism may protect you from faults on Web server nodes, you still need to share data through central storage nodes. GFS-a Linux free Cluster File System-allows you to create a truly stable

Unlike the scalability design of a cache server cluster, the scalability of the data storage server cluster demands higher data durability and availability.The purpose of the cache is to speed up the data read and reduce the load pressure on the data storage server.Therefore, the loss of some cached data does not affec
