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

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 installation in CentOS (rpm package depends on installation) CentOS is a Community version of Red Hat Enterprise Linux. centOS fully supports rpm installation.

However, although the rpm package is easy to install, it depends too much, it is convenient to use the yum tool for installation, but it is greatly affected by the network bandwidth.

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
