I am in the idea stage for something I am not positive is entirely worth the effort and I am in totally uncharted territory.
I am not sure what terminology is i am looking for here... what i am thinking i want to do is: have 2 hosts one a mirror of the other including all vserver guests etc. the 2 machines are identical in every way. rather than have the mirror machine on 'standby' waiting for some fateful day it is needed, i would like both servers and all guests to be running simultaneously. this would be accomplished by having everything running unique private network ip addresses. this would allow adding additional 'mirror' machines as necessary. the existing public ips from the production server we have running would be moved to some 'control' computer which would have a listing of the private ips that would serve what the public ip wants and would call on either one as needed. if one of the private ip servers doesnt respond (down) the control computer would simply choose the working ip until the first one comes back online. what do i need to do in the 'control' machine to accomplish this? is this some kind of configuration that already exists in the linux distro? we run gentoo. beowolf (whatever that is)? is there another way of accomplishing what i wish to do? also how messy will keeping the mirror machines 'in sync' be? would i be better off having all machines but the controller share a common nfs mount for all the guests? some of these virtual servers are very high volume usage so if all the data must route through the control computer, i am thinking that computer would have to be a monster. or maybe have several control computers each handling a different class of service. sorry if i sound like i have no clue what i am talking about, but that is the truth :) , i only think i know what i want to accomplish. -- Chuck _______________________________________________ Vserver mailing list [email protected] http://list.linux-vserver.org/mailman/listinfo/vserver
