Distributed replicated Block Device (DRBD) is a software-free, shared-sharing, storage-replication solution that mirrors the contents of a piece of equipment between servers. Data mirroring: Real-time, transparent, synchronous (returned after all successful servers), asynchronous (returned after the local server succeeds) DRBD's core functionality is implemented through the Linux kernel, closest to the sy

. • III. The principle of replication The master node counts the actions in oplog, copies each document from the master node when the node is started, and then obtains the oplog of the master node and performs the operations in order to achieve data synchronization. Oplog is saved in the Local.oplog collection, the master node maintains a Syncedto property, the primary node passes through the Db.slaves.find (), and the node is db.sources.find () V

Original: HTTP://ANTIREZ.COM/NEWS/45 Author: Antirez Weblog As I wrote in a previous blog post, I am currently developing some of the resynchronization features of Redis slave. Our idea is that we have a backup log of the replication stream that can reach the specified number of bytes (by default it will be hundreds of megabytes). If a slave connection is lost, it will establish a connection again, see if the master's Runid is the same, and ask to c
