Chang, you are not listed as a developer of this project. see http://tracker.ceph.com/projects/ceph. probably you ping any of the tech leaders (see "Manager" in the same webpage) to get you added?

Thank you, Kefu, I will write a emall to get permission. : )

This is fixed, right? I haven't seen it in a couple weeks.

i don't think it's fixed. we merged a PR by Chang to print more log on the "couldn't get command descriptions for [mgr...]" failure.

ok, downgrading and updating status. maybe this is secondary effect of having a flaky mgr (which is pretty stable now).

and the mgr was online happy.

I think that EACCES is coming from MgrClient.cc:

../src/mgr/MgrClient.cc:    ldout(cct,20) << " no MgrMap, assuming EACCES" << dendl;
../src/mgr/MgrClient.cc:    return -EACCES;

because we haven't gotten mgrmap from the mon. The maps are sent in alphanumeric order, which means that if we wait for osdmap, we'll have already gotten the mgrmap (and we'll avoid a potential problem with tell to an osd without an osdmap).
