Hi There,


I have followed the guide in "Clusters from Scratch" written by Andrew Beekhof and successfully setup an Active/Passive pair of cluster servers. The cluster runs in Fedora 13 and includes services like apache, vsftpd and nfs. Drbd is used to allow data consistence during a failover. Everything works fine except ftp lose its connection when the service swaps from primary to the secondary or vice versa. I know to keep the ftp connection, one may need to keep the connection states for the session across the nodes. But I couldn't find clue how to do it. Does anyone there have any idea how to keep the ftp connection when swapping nodes, if it is possible?
