Description
Description of problem¶
when more than N/2+1 monitors go down, the Dashboard mon report is incorrect
Environment¶
Reproduced in Nautilus-Pacific.
How reproducible¶
Steps:
- Launch 3-mon (a, b, c) vstart cluster
- Kill 1 mon (b). Dashboard reports only 2 mons in quorum (a, c)
- Kill another mon (c)
Actual results¶
Dashboard keeps reporting (in Landing page and in cluster->mon page) 2 mons in quorum (a, c).
Expected results¶
Dashboard reports should report no quorum and only 1 mon (a) out of quorum, while the others are simply unavailable.

As discussed in today's CDM, Neha suggested exploring the use the beacon approach (heartbeat-like) to detect the out-of-quorum situation. RADOS team will check and come up with a proposal.
