<p>I'm building a cheap iscsi storage. I have two nodes with 1,4GB storage each and I'm thinking of two ways of doing this:<br clear="all"></p><p>1. 3ware raid controller -> one big drbd device -> lvm -> export volumes via iscsi</p>
<p>2. 3ware raid controller -> lvm -> multiple drbd devices -> export via iscsi</p><p>What's the safest/fastest method?</p><p>Will multiple drbd devices affect performance? There should be no more than 8-10 drbd devices in this setup (if I stick to the second method). I'm tempted to go with the second one because it seems safer (for example, if I have problems with one drbd volume, I can still use the others). What's your opinion?</p>
