That's a good place to look for sure but it all started when my storage went down, nothing was changed on the servers. The storage seems fine now, it was just one side of the power supplies that went down but it cause loss of connection to the cluster. Since then, can't reach anything, always segmentation errors. The hardware can be seen, I can create LVM partitions, just can't do anything else. Mike -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
