Firstly what we're talking about here is "--set". From the man page: --set tcp tcpfin udp Change the timeout values used for IPVS connections. This com- mand always takes 3 parameters, representing the timeout values (in seconds) for TCP sessions, TCP sessions after receiv- ing a FIN packet, and UDP packets, respectively. A timeout value 0 means that the current timeout value of the correspond- ing entry is preserved. So... Nothing - well, I mean *almost* nothing - in a raw, unadulterated (by any management applications) IPVS/LVS is persistent. The kernel boots; the modules are loaded (or compiled in) and at this point the only persistent things are the default compile-time settings (hash size and so on). At this point you don't have an LVS, so something else - not the LVS/IPVS framework itself - is doing the configuring. It strikes me that the management app (whether home cooked, rc.local, Piranha, Keepalived, ldirectord or anything else folks might mention) has the job of making settings persistent. That said, you're right that "-S" doesn't output the timeout settings. That could, I guess, be changed - but there will still be a large number of systems out there without it, which will still need to manage that setting in some way by themselves. I believe you'd be better off tweaking Piranha's pulse (or whatever the daemon is called) to handle this with a configuration option, in the exact same way it's configured with virtual services. It's perhaps notable that neither keepalived nor ldirectord do this.
