We've been doing it for years, and almost all the problems could be traced to A) someone unplugging the wrong network cable B) someone doing something stupid to drbd.conf. So, yeah. > I can co-locate two servers in two datacenters with a > private VLAN for replication between both, is this a > sound solution or is RTD a big issue ? EXPN "RTD", plz, kthx? Er... it works well between 2 datacenters that are about 20 miles apart. The ~1ms latency combined with protocol C means writes are slower than they would be if the boxes were right next to each other. Sustained speeds are about 35M/s. I spent days fooling with many settings in drbd.conf and couldn't find any way to get any statistically significant improvement on that. -- Matt G / Dances With Crows The Crow202 Blog: http://crow202.org/wordpress/ There is no Darkness in Eternity/But only Light too dim for us to see
