First, I hope this is ok to post this question in this email list... Secondly, I have been reading the Users Guide at http://www.drbd.org/users-guide/ - but still have a few "before I start" type of questions. I am wanting to create a high-availability cluster and I *think* DRBD is what I am looking for. But I'm not quite sure. My *thought* was to use DRBD to mirror the /home filesystem between the 2 machines - but I have someone working for me that is saying the DRBD mirrors "entire systems". If he is correct, wouldn't that mean that 2 computers would require the exact same hardware? Or am I not even thinking of DRBD in the correct terms? After all, a "true high availability cluster" would mean my down time is measured in seconds, right? I would not have that if all I am mirroring is /home... My systems (if it matters): I have one disk array (10TB, Raid5+1) with /home on it's own filesystem using 7.2T (according to the df command). This machine is in production and has been in use for a couple of years now. I have another system that is completely blank and ready to configure any way that makes sense. It has 2 250gb drives in a hardware Raid0, and 8 2tb drives in a hardware Raid5 (currently Raid5+3 - trying to give me 8tb of space). So - where do I start? By that I mean - I am unsure of even how to partition the drives on the new system: do I use LVM, or attempt to use partitions similar to the old system?
