                A mirror is set between the local node and a remote
187 
                one, which must be specified with the --secondary-node
188 
                option. Use this option to obtain a highly available
189 
                instance that can be failed over to a remote node
190 
                should the primary one fail.

              A mirror is set between the local node and a remote one, which
187 
              must be specified with the second value of the --node option. Use
188 
              this option to obtain a highly available instance that can be
189 
              failed over to a remote node should the primary one fail.

        For example if you want to create an highly available instance
199 198 
        use the remote_raid1 disk template:

      <synopsis>gnt-instance add -n <replaceable>TARGET_NODE</replaceable> -o <replaceable>OS_TYPE</replaceable> -t remote_raid1 \
