That is what you get for not providing enough context ;) DRBD is for replication between two nodes, which typically form a HA cluster and/or desaster recovery group. DRBD is not the "I want my SANs to replicate, but don't want to pay the licence" solution. DRBD is the solution to _replace_ your single SAN box with a clustering solution, using e.g. Pacemaker + DRBD + iSCSI (+ NFS, + SAMBA), and direct attached storage on the cluster nodes. For the price of one SAN, you can get the whole cluster + LINBIT support ;) Of course, that does not help you once you have those SANs already. So, YES, of course you can utilize DRBD to replicate between SANs, as well. Typically you'd have your SANs in different fire section (or different sites, even), and have (at least) one DRBD "head" node for each SAN. We at LINBIT have encountered quite a few interesting setups in that area. If you want to repliate within _one_ node, however, that is not DRBD's job. -- : Lars Ellenberg : LINBIT | Your Way to High Availability : DRBD/HA support and consulting http://www.linbit.com DRBD® and LINBIT® are registered trademarks of LINBIT, Austria. __ please don't Cc me, but send to list -- I'm subscribed
