Sebastian, Those errors are normal following an outage of this sort. Hintfiles will be regenerated during the next bitcask merge and any data file that is incomplete or has invalid entries will be truncated. This does result in a loss of replicas but as long as at least 1 replica of the data is not lost the replicas can be repaired by manual repair or read-repair. The manual repair procedure is outlined here: http://docs.basho.com/riak/1.2.0/cookbooks/Repairing-KV-Indexes/ .
I recommend that you manually repair any partition that discarded data file entries but other than that your cluster should be working fine.
