Ceph installation and deployment in CentOS7 Environment Ceph Introduction Eph is designed to build high performance, high scalibility, and high available on low-cost storage media, providing unified storage, file-based storage, block storage, and Object Storage. I recently read the relevant documentation and found it interesting. It has already provided Block Storage for openstack, which fits the mainstream

Of course, we can also use different CGI front ends by specifying the address and port:$ sudo docker run-d--net=host \-v/var/lib/ceph/:/var/lib/ceph \-v/etc/

inconsistencies in the data that exist. Scrubbing can affect cluster performance. It is divided into two categories:· A class is the default daily, called light scrubbing, whose period is determined by the configuration item OSD Scrub min interval (default 24 hours) and OSD scrub max interval (default 7 days). It discovers minor inconsistencies in data by examining the size and properties of the object.· The other is the default weekly, called Deep s

storage service, and file systems cannot meet the requirements of GlusterFs. Therefore, each has its own advantages.
