Depends on nature of quorum loss. If 2 of 3 intances just die or their network is permanently cut then the remaining node will reject both reads and writes due to no. 1 above. Then manual intervention is needed to restore network and/or the broken machines. The auto recovery is specifically for the scenario when the nodes come back up but with different IPs and try to form the cluster again. This previously required manual intervention in v0.24, but with 0.25 RC (which is still a beta build) we can handle this. Still needs more testing.
