whole storage system. A group can consist of one or more storage servers, and the files in a storage server under a group are the same, and multiple storage servers in group play a role of redundant backup and load balancing (one group has storage capacity of the smallest storage server in the group. Different groups of storage servers do not communicate with each other, and storage servers within the same group are connected to each other for file synchronization. When adding servers to the gr

Integration with Bug Tracking System/problem tracking In software development, modification depends on a bug or problem number. Users of the Bug Tracking System (problem tracker) like to associate the modification of the subversion with a specified number in the problem tracking. Therefore, many problem trackers provide a pre-submitted hook script to analyze logs and find the submitted bug numbers. This is slightly less reliable, because it relies o

Install, configure, and migrate FastDFSV3.02Background: We used fastdfsV3.02 on the original server, and now we want to migrate it to the new server. There are no relevant documents on the Internet and it has been a long time. Now we will record the migration process as follows to facilitate the configuration and migration of other students.Tracker server: 192.168.1.246 Storage Server: 192.168.1.246 Deploy tracker and storage on the same server when

). The direction of the packet can also be obtained by ctinfo/ip_ct_is_reply, but a more convenient macro ctinfo2dir (Ctinfo) can be used, defined in Connection Tracker The connection tracker is a very important part of the connection tracking architecture and relates to the implementation of the State firewall. Its main task is to find the corresponding connection information for an IP packet and ensure

1, picture access exception problem descriptionBuild a new environment of the Fastdfs file server, just set up the time, uploaded a picture, normal, but because the port is not open, there is no authentication access problem. The environment is being shelved for testing.Later in the test, because there are too many image files to upload, so directly copy the production environment DFS data directory, replace the data directory of the new environment, and the following files are still used in the

control services with Visual Studio, you must have VSS or an alternate provider installed on each source control client. Install the visual SourceSafe 6.0c as the MSSCCI provider to run Setup.exe from the root directory of the visual SourceSafe 6.0c version of the installation CD. After you install the source control provider, the next step is to create a source control database to store the server version of your team's shared files.

management is certainly not beyond it. However, as we have mentioned, the particularity of the open source software development model also puts forward new and stricter process requirements for its bug tracking and management process. In this case, it is necessary to have a more correct understanding of the defect tracking system (bug Tracker) first. Defects include product errors, requirements and design changes, new features or extensions (Feature,
