Hello, I have a ceph cluster running bobtail 0.56.4 I have been playing with the rbd images and kvm. The hardware for the osd,mon is 3 x HP G5 and 2 x SATA 2TB disk. and 2xSAS for the journals. (Old hardware) I have one host running kvm-rbd against the setup. The network is 1GB network. The scenario is as follows. I run my vm servers for some day/s then it hangs the cluster starts to recover and 2 osd+mon are down. And i have to restart that server. Health goes to OK after recovering and I can continue. I have noticed that i get high load related ceph-mon and osd on one of the hosts. The host that get high load is not always the same. I guess that’s the host that the kvm-host uses for mon. What i can't figure out is why the osd's are stopping/crashing. And all load is sent to only that server mon, if that's what is happening ???? Is it's possible to limit something. It feels like i'm overloading the system ???? I have not turned on debug. Please let me know if any logs would be of any interest. /Best Regards Martin -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
