Hi Laura and Emilio. This morning, after a brief struggle with zen2 interface configuration, I managed to set up the cluster in the "production" environment. As I said before I had to substitute the cross cable on cluster interface with a patch connected to a switch (in a private vlan) otherwise the RSA communication wouldn't work.
I tried few times the failover process and everithing went good. I noticed that the time needed to see the website up again is about 10 seconds. Is it a time needed by the sync process or an ARP matter? Does ZEN send gratuitous arp during the failover process? In Italy we say: "el apetito viene comiendo". So another request about cluster: * would be possible in the future have ZEN checking not only the cluster interface to decide a failover? Anyway, enjoy your vacation, I'll let you know about our stress tests in september. For the moment thanks a lot for your work. Ciao. Stefano. ________________________________ Da: Emilio Campos [mailto:[email protected]] Inviato: venerdì 12 agosto 2011 19.52 A: [email protected] Oggetto: Re: [Zenloadbalancer-support] R: (no subject) Hi Stefano, Thanks about your test, and still not on vacation, soon, the end of this next week!!!! lol We are working for solve the issues reported by you and Dave, will be added on the new release, with improvements like a new concept: "profiles", for advanced configuration with http and https protocols. And about the backup commented on your mail, you're right, Im going to modify the process of "backup import", adding a "return to fabric status" before import the configuration. For all members of the list; thanks about your tests and suggestions. 2011/8/11 Chiesa Stefano <[email protected]> Hello again. I tried the failover and it worked good. I made zen servers change their role many times and they never messed anything up. So I learnt/think: * the MAC mess is just a display problem (and only on the passive device) * never use a cross cable on cluster interface It seems rc4 it's a big jump forward... Now I'll try the upgrade on the two production server and then the cluster configuration. In relation to the restore procedure it seems that it simply copies the previously backed up files but not restores "a situation". To explain: if I made a backup before a cluster config, then I configure the cluster and later restore the previous backup the cluster configuration remain configured. I'd find more useful if the files missing before the backup (and created later) were deleted by the restore program. Matter for the next rc's Anyway, go on holyday! Ciao. Stefano. ________________________________ Da: Chiesa Stefano [mailto:[email protected]] Inviato: giovedì 11 agosto 2011 15.42 A: [email protected] Oggetto: [Zenloadbalancer-support] (no subject) Hello Laura and Emilio, still not on vacation? I'm just came back and as promised I put up the test lab. I built two zen server with a simple configuration: * one "farm" interface * one gui if * one cluster if (cross cable) And then I tried to create the cluster. As before I didn't manage to create it. It generated always an error during the RSA connection creation. Reading Dave posts I decided to change the connection type on the cluster if, I removed the cross cable and connected the two if through a switch. And it worked. Now this is the cluster page on ACTIVE host ZENLAB-1: Zen latency is UP on zenlab-1 172.16.99.1 | Zen latency is UP on zenlab-2 172.16.99.2 Cluster IP 172.16.99.3 is active on zenlab-1 Zen Inotify is running on zenlab-1 Global status: (ok) But on ZENLAB-2: Zen latency is UP on zenlab-2 172.16.99.2 | Zen latency is DOWN on zenlab-1 172.16.99.1 <https://10.39.160.242:444/img/icons/small/exclamation.png> Host key verification failed. <https://10.39.160.242:444/img/icons/small/exclamation.png> Zen Inotify is running on Host key verification failed. <https://10.39.160.242:444/img/icons/small/exclamation.png> Global status: <https://10.39.160.242:444/img/icons/small/exclamation.png> And, as Dave, I have a strange display of MAC addresses on GUI on ZENLAB-2 : Settings::Interfaces Table Interfaces Name Addr HWaddr Netmask Gateway Status Actions eth0 1.1.1.241 00:50:da:81:db:d7 255.255.255.0 - down <https://10.39.160.242:444/index.cgi?id=3-2&action=upif&if=eth0> <https://10.39.160.242:444/index.cgi?id=3-2&action=editif&if=eth0&toif=eth0&source=files&status=down> <https://10.39.160.242:444/index.cgi?id=3-2&action=addvip&toif=eth0> <https://10.39.160.242:444/index.cgi?id=3-2&action=addvlan&toif=eth0> <https://10.39.160.242:444/index.cgi?id=3-2&action=deleteif&if=eth0> eth1 <https://10.39.160.242:444/img/icons/small/application_home.png> 10.39.160.242 00:0f:fe:13:f7:95 255.255.224.0 - up <https://10.39.160.242:444/index.cgi?id=3-2&action=addvip&toif=eth1> <https://10.39.160.242:444/index.cgi?id=3-2&action=addvlan&toif=eth1> <https://10.39.160.242:444/img/icons/small/lock.png> eth2 <https://10.39.160.242:444/img/icons/small/databases.png> 172.16.99.2 00:10:5a:be:f5:69 255.255.255.248 - up <https://10.39.160.242:444/index.cgi?id=3-2&action=addvip&toif=eth2> <https://10.39.160.242:444/index.cgi?id=3-2&action=addvlan&toif=eth2> <https://10.39.160.242:444/img/icons/small/lock.png> eth2:cl <https://10.39.160.242:444/img/icons/small/databases.png> 172.16.99.3 00:10:5a:be:f5:69 255.255.255.248 down <https://10.39.160.242:444/img/icons/small/lock.png> eth0.1 1.1.1.100 00:10:5a:be:f5:69 255.255.255.0 down <https://10.39.160.242:444/index.cgi?id=3-2&action=upif&if=eth0.1> <https://10.39.160.242:444/index.cgi?id=3-2&action=editif&if=eth0.1&toif=eth0.1&source=files&status=down> <https://10.39.160.242:444/index.cgi?id=3-2&action=addvip&toif=eth0.1> <https://10.39.160.242:444/index.cgi?id=3-2&action=deleteif&if=eth0.1> Now (as maybe it's just a GUI problem) I'll try the failover and I'll let you know.
