Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


I'm a new drdb user but as far as I can tell you'll need a cluster
filesystem like GFS or OCFS2 running on both nodes and then you "share"
with NFS. Note that that would still make it an active-standby solution
since the alias IP can only be on one of the two machines
