Hi, So, I am writing a module to install and configure ucarp. There is only one module in puppet forge and that is not that good. In ucarp, same configuration files have to be served on two servers and to configure the host I am defining a custom resource ucarp::host::config. So, for using, I''ll have to create this resource two times on two diff...

Has anyone successfully setup a shorewall Ucarp solution?

hi i''ve not found many hints on shorewall/ucarp/conntrackd topic. i''m sharing this with the list, so that i''m able to search and find it the next time. :) i''ve setup 2 identical systems with shorewall, ucarp and conntrackd in an active/backup way. ucarp just calls ifup/ifdown, all network configuration is maintai...

Hello everybody. I have a problem setting up gluster failover funcionality. Based on manual i setup ucarp which is working well ( tested with ping/ssh etc ) But when i use virtual address for gluster volume mount and i turn off one of nodes machine/gluster will freeze until node is back online. My virtual ip is 3.200 and machine real ip is 3.233 and 3.5. In gluster log i can see: [2011-06-06 02:33:5...

..........| .................LAN B LAN A is my primary (external) LAN. LAN B is my wireless LAN. LAN A does iBGP and OSPF routing. Each wireless router does the following: 2 Bridged Ethernet + STP connections to LAN A 2 Bridged Ethernet + STP connections to LAN B 2 VLANs on LAN A 5 VLANs on LAN B UCARP on each wireless VLAN (5). Quagga - zebra, bgpd, ospfd (on LAN A) UCARP provides a virtual IP address for the gateway for each VLAN on the wireless side. The goal is to provide complete, hot-failover redundancy to wireless-r2 in the event wireless-r1 goes down (maintenance, failure, etc). Ideally...

Morning Folks, should I prefer NFS with UCARP or native GlusterFS mounts for serving the system images to XCP? Which one performes better over 1G network links? NFS is probaby easier to setup due to existing tools like rpcinfo and showmount, both are used inside the storage container code, and there is some code for NFS, not for GlusterFS...

Hi, we've successfully configured GlusterFS mirroring across two identical nodes [1]. We're running the file share under a Virtual IP address using UCarp. We have different clients connected using NFS, CIFS and GlusterFS. When we simulate a node failure, by unplugging it, it takes about 5 seconds for the CIFS and GlusterFS clients to refresh the connection and continue operation. The NFS client goes stale. Any connection (like an ongoing copy) w...

All, We are in the process of determining a virtualized infrastructure and wanted to hear from current users of Gluster and VMWare. What we were looking to setup was an HA ESXi cluster (2 heads) with gluster backend (4 bricks to start, replicated/distributed), all backend connectivity would be 10Gbe. Mainly the storage would be for VM images but may include NAS files later. So our

Has anyone toyed with using Shorewall in conjunction with the userland implementation of the OBSD-based common address redundancy protocol? Would like any preliminary feedback before I devote time to the project.

...p; brought the entire system down. Luckily we are testing the FW and other servers, so we did not loose anything. Now we have decided to setup two Shorewall FW servers with a primary & another fallover FW server. I have done some research cruised the Internet and found that a product ''UCARP'' (http://www.ucarp.org/) might provide a solution. Our current setup is (same as on Shorewall web site) as follows: T1 ---- | Cisco 26xx Router -...

Hi. Is anyone using conntrack-tools to implement gateway failover on a network with windows clients? I set it up with ucarp and keepalived, and found that gratuitous ARP doesn''t always seem to update the cache on Windows machines. It works the first time, but if a second failover happens, the client continues to send stuff to the wrong MAC address. Linux machines work fine. I''ve noticed similar report...

Hi. I''m wondering if there''s a good way to configure a Linux firewall box to failover to a single backup server, while preserving connection state. This question has been asked before, but the latest reference I can find is from 2004, at which time Linux had no equivalent of OpenBSD''s pfsync, though Harald was said to be working on one. Did anything come of those

Hi all! I think I remember there have discussion on this topic on this mailinglist a while ago. But the archives don''t find anything. Did anyone here set up a configuration with shorewall and heartbeat or vrrpd or ucarp? What would you prefer? Any experiences with failover times, setup problems etc? Good documentation on this?

Oh! In that case ignore it. Asterisk won't rebind the adapter if you've only changed parameters.

Hi, I have two Gluster servers A and B. They are mirrored. I mount A. What happens when server A goes down? I would like for my applications to seamlessly use data from the Gluster storage B. Thanks, Sergiy.

Hi, I have a virtual IP which migrate from one server to another depending the server status. I have a problem with this behaviour and samba. When the IP migrates to another server, in the first server samba is stopped. When the IP is going to come back to the first server, samba is started and after that the IP come back. The problem is: Samba (smbd) doesn't bind the IP because it is

I''ve tried to implement puppetmaster High Availability (mon+heartbeat). Herefore, the puppet client and puppet master are running on both servers. When the puppet client starts up, it generates a certificate, public and private key for the machine it runs on. When the puppet master starts up, it changes something so that the puppet client have no valid certificate anymore (the

I''m expermienting with Shorewall for use protecting my servers(about 25 all currently using pub addresses). My pointy-haired-boss is somewhat sceptical about adding a firewall that would be a single point of failier for our services. Does anyone have a good set of documentation that I could use in setting up either an Active/Active or Active/passive setup with two identical shorewall
