Hi, cepher I have a cluster of 6 OSD server, every server has 8 OSDs. I out 4 OSDs on every server, then my client io is blocking. I reboot my client and then create a new rbd device, but the new device also can't write io. Yeah, i understand that some data may lost as threee replicas of some object were lost, but why the cluster become unavailable? There 80 incomplete pg and 4 down+incomplete pg. Any solution i could solve the problem?
