Dear DRBD users, this is first RC1 of the upcoming drbd-reactor version 1.2.0.
There are two noteworthy changes in this release: - The promoter plugin used a shell wrapper script shipped in drbd-utils to handle OCF agents. This wrapper was replaced by a proper Rust binary. The advantage is that we can (re)use that in our Windows port. Every shell script re-written in a proper programming language is a benefit on its own. - So far it was possible to specify an "id" for plugins in their configuration snippet and that was the handle to decide which plugin instances got stopped, kept alive, or started on drbd-reactor reloads (systemctl reload/kill -HUP). Now we keep hashes of the configuration structs (i.e., they are trait Hash) and reloading changed plugins just behaves like expect: No weird "id"s, changed plugins restart, new get started, unchanged ones stay, the ones now without a config get stopped. The "id" fields in configs are now marked as deprecated (i.e., specifying them prints a warning in the log) and don't have any special meaning anymore. Note that they still contribute to the hash of config struct. In order to make the config structs trait Hash we had to change the 'sleep-before-promote-factor' from a f32 to a u32. I guess this setting is that unknown and rarely used that we can do that. In the best case you don't even notice the changes, but get an improved behavior on reactor reloads. If there are not reported issues, the final release will follow in about a week from now.
