Hi, It really depends on type of power failure ...Normal poweroff of the cluster is fine ... I've been managing large cluster and we were forced to do total poweroff twice a year. It was working fine: we just safely unmounted all clients, then set noout flag and powered machines down.
Powercut (hard shutdown) can be a big problem and I would expected problems here.

Hi I am very new to Ceph. Studding for few days for a deployment of Ceph cluster. I am going to deploy ceph in a small data center where power failure is a big problem. we have single power supply, Single ups and a stand by generator. so what happend if all node down due to power failure? will it create any problem to restart service when power restore? looking for your suggestion.. -- *Regards*Santu Roy
