Ceph Users


The general mailing list for Ceph users.


For real-time chat, the Ceph community gathers in the #ceph channel of the Open and Free Technology Community (OFTC) IRC network. Created in 1988, Internet Relay Chat (IRC) is a relay-based, real-time chat protocol. It is mainly designed for group (many-to-many) communication in discussion forums called channels, but also allows one-to-one communication via private message. On IRC you can talk to many other members using Ceph, on topics ranging from idle chit-chat to support questions. Though a channel might have many people in it at any one time, they might not always be at their keyboard; so if no-one responds, just wait around and someone will hopefully answer soon enough.


If you intend to use the on a continued basis, you are advised to register an account. That will give you a unique IRC identity, and will also allow you to access channels where unregistered users have been locked out for technical reasons.
