Hello and thank you very much to yours Gianluca and Andreas. which kind of cluster? Only Primary - Secondary drbd cluster. which kind of Linux distribution/release? Debian lenny in both nodes. which kind of usage then of the LVs/FS to be created? LVs will be iscsi targets for a xen server. I believe clvm will be useful. Again, thank you very much Gianluca.
