Redhat's Ceph and Inktank code libraries were hacked RedHat claims that Ceph community projects and Inktank download websites were hacked last week and some code may be damaged. Last week, RedHat suffered a very unpleasant accident. Both the Ceph community website and the Inktank download website were hacked. The former is the open-source

Summary of Ceph practice: CephFS client configuration, cephcephfsBecause CephFS is not very stable at present, it may be used in more experiments. Before proceeding to this chapter, you need to complete the basic cluster building, please refer to the http://blog.csdn.net/eric_sunah/article/details/40862215 You can attach a file system to a VM or on an independent physical machine. do not perform the following operations on the machine in the

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

Centos 6.2 64-bit kernel version is 2.6.32-220. el6.i686 and CEpH clients have been integrated in Versions later than 2.6.34. Obviously, centos6.2 does not have a Client client. Since I have installed ceph0.47.2 in Ubuntu 11.10 64-bit, in addition, the kernel version of ubuntu 11.10 is 3.0.0-12-generic, so it naturally contains the CEpH client. For convenience, I plan to perform experiments according to the

So the first is whether there is a problem with the Gluster FS version, the deployment of glusterfs hardware and software whether there is a problem starting, but always find no real reason. At this time the company process is a hindrance, because the reason is based on empirical speculation, even if a little bit of code, to be tested, to find a number of leadership signature, the

Glusterfs six volumes to explainFirst, the distribution volumeThe distributed volume file is randomly distributed across the entire brick volume. With distributed volumes, you need to extend storage, redundancy is important, or provide additional hardware/software layers. (Simplified: Distributed volumes, where files are randomly distributed through hash algorithms to volumes made up of bricks. The resources in the volume are stored only on one server

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
