Thanks Helmut, Please bear with me, I'm a relative novice! A couple of more questions ... >Install everything first, reserve enough disk space for DRBD->partitions. Then make the partitions, configure DRBD, then >configure the services. Q1: Do you mean install all (OS and applications) identically on both machines and then configure DRBD, services? Or can I install all on one and just the OS on the second, put in DRBD on both, configure the services and see all replicated to the second? I am starting from scratch. >DRBD is a block device. You can use it for (nearly) everything >like a partition of your harddisk. For failover of services, >related DRBD-resources and related IP you need something like >heartbeat. Q2: You mentioned heartbeat, and I see it's included in the 9.1 distro. Is this to be installed and configured after DRDB but before the services? Or last? >Mainly you should mirror the data space of your services, maybe >the logs. Yes, or unison e.g. But again, mirroring _everything_ >will not work. You have to exclude some directories and some >files. Q3: Is there a list somehwere? Apart from data, how do I know that on primary fail, some essential service hasn't been left out from the secondary because I did not include some directory on the primary for mirroring? Sorry if the questions appear naive. Thanks.
