Ceph deadlock failure under high IO

Ceph deadlock failure under high IO On a high-performance PC server, ceph is used for VM image storage. In the case of stress testing, all virtual machines on the server cannot be accessed. Cause: 1. A website service is installed on the virtual machine, and redis is used as the cache server in the website service. When the pressure is high (8000 thousand accesses per second), all the VMS on the host machin

Some Ideas about CEpH tier

The CEpH experiment environment has been used within the company for a period of time. It is stable to use the Block devices provided by RBD to create virtual machines and allocate blocks to virtual machines. However, most of the current environment configurations are the default CEpH value, but the journal is separated and written to a separate partition. Later, we plan to use

Ceph in hand, the world I have

Someone asked me, how did you manage to do the unified storage? I smiled, loudly told him: Ceph in hand, the world I have. Ceph is a unified distributed storage system designed for outstanding performance, reliability, and scalability. After the adoption of OpenStack as the eldest brother is a very out of hand, by everyone's extensive attention. Of course, this is because it provides a variety of reliabl

Ceph source code analysis: Network Module Because Ceph has a long history, the network does not use the epoll model that is currently commonly used, but uses a multi-threaded model similar to MySQL. Each connection (socket) has a read thread, read data from the socket continuously. A write thread writes data to the socket. Multi-threaded implementation is simple, but the concurrency performance is not flatt
