Sometimes replicas may have to be replaced. A replica can become 
corrupted, for example, and in that case needs to be removed and then 
recreated. The procedure to do that is as follows:
1. Remove all existing replicas with the following command:
Do not reboot the system after removing replicas! With replicas gone, 
the system may not boot!
2. Recreate two replicas on the same partition:
