<div>It is fine for using more journals.</div>
<div>I think there would be some performance penalty, although I'm not sure about it.</div>

<div>If you only export 1 DRBD, you are doing backup, which do not need to exporting both DRBD.</div>
<div>However if you are exporting 2 DRBD, it can provide HA functions. In order to do this, you need to make 2 DRBD to be primary and set the parameter in exporting with GNBD. Otherwise, the client machines cannot map the 2 DRBD devices into one.</div>
