Hi list, on the weekend one of five OSD-nodes fails (hung with kernel panic). The cluster degraded (12 of 60 osds), but from our monitoring-host the noout-flag is set in this case.
But around three hours later the kvm-guest, which used storage on the ceph cluster (and use writes) are unaccessible. After restarting the failed ceph-node the ceph-cluster are healthy again, but the VMs need to be restartet to work again. In the ceph.config I had defined "osd_pool_default_min_size = 1" therefore I don't understand why this happens. Which parameter must be changed/set so that the kvm-clients still working on the unhealthy cluster? Ceph-version is 0.72.2 - pool replication 2. Thanks for a hint.
