direct links of old sources may well be a few messages off.
I would do it like so.... 1. Setup DRBD to sync locally and do your initial sync. 2. Stop the DRBD/heartbeat daemon on the secondary and make sure it is not going to restart under an rc script when it boots the next time. 3. Stop DRBD/heartbeat on the primary and be sure it too is not loading DRBD/heatbeaton boot up. 4. Ship the secondary to your remote location. 5. Update the drbd.conf and ha.cf to have the correct new IP information (after testing you have a good connection of course) and pay close attention to your timeouts as a little latency in a link may cause heartbeat or DRBD to be flopping all over the place. 6. Startup drbd and heartbeat then test for failover using hb_standby or whatever else you want to try. Be sure you are using protocol C too. (Though, here is no real reason to ever using anything but protocol C) One question though, I assume your subnet spans the WAN? It will have to for heartbeat to work. You can't have subnet 10.1.1.0 here and 10.2.2.0 there and share an IP unless you get creative with the IPs you bind. Think about this long and hard as you don't want to do through the trouble and find a scheme doesn't work or requires 3 weeks of rework. ________________________________________ Chip Burke -----Original Message----- From: drbd-user-bounces at lists.linbit.com [mailto:drbd-user-bounces at lists.linbit.com] On Behalf Of Laurent CARON Sent: Thursday, February 23, 2006 12:49 PM To: drbd-user at lists.linbit.com Cc: romain.bottan at celsecat.com Subject: Re: [DRBD-user] drbd solution for distant sites ?
