It will loop and wait the dashboard module to start forever.

Xiubo, I think you're missing some dependencies. Have you run `./install-deps.sh`?

Yeah, all the install-deps.sh and do_cmake.sh no any error. But I have to manually install all the them again to make this work.

It seems the install-deps.sh does not work well in centos release.

I had the same issue on fedora 30 with yaml module not installed.

I just ran into this same issue, where "waiting for mgr dashboard module to start" runs on a loop. Checking mgr.log.x in ceph/build/out told me that one of the lines I had added to mgr_module.py was indented incorrectly. Fixing the indent solved my problem.

For anyone else running into this issue, make sure to check the output of your logs! (ceph/build/out/**.log) They are very helpful.

I know this issue has already been closed, but I wanted to add more context to it in case any other developers are stumped by the same scenario.
