Backport #16549
Updated by Loïc Dachary almost 8 years ago
https://github.com/ceph/ceph/pull/10036 we are using cluster.mon_command() in rados.py to do with *perfix*="osd pool stats",format="json", monitor will assert Recheck the code we wrongly make "prefix" to "perfix" :( , and anything other than "prefix"(say "abc") will kill the monitor. This is dangerous as anyone has access to the rados can take down whole cluster. [Bug seem in hammer 0.94.6, not tested against other version
