dhcpd has clustering capability included, I want to use that capability.
Ah, I wasn't aware of that.
Linux-HA is not sufficient, as this doesn't synchronize the DHCP leases between the clustering nodes. I.e., in the case of failovers the new node would not know about leases of the previous node any more. Usage of ISC dhcpd's failover capabilities avoids that problem.
Actually, that's where drbd comes in. It's essentially a RAID1 over the network.
As I wrote, I know about the technology already. I am interested in in-depth treatment of pitfalls and strategies for implementation, in the stuff that's not elaborated in product manuals and IETF RFC drafts.
Sorry, like I said I wasn't even aware of the clustering abilities of dhcp - we simply use Linux-HA, which does the trick. /Per Jessen, Zürich -- http://www.spamchek.ch/ - managed anti-spam and anti-virus solution. Let us analyse your spam- and virus-threat - up to 2 months for free.
