similar to: Is mirroring provides failover protection?

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

Hi, I''m trying to figure out how to use Linux QoS. Default setting has three queues (bands) and should prioretise outgoing tarffic based on TOS field. I try to test that by flooding Ethernet interface by netperf or iptraf and running ping -f with -Q and without Q. -Q doesn''t affect ping results, it suffers anyway. It seems that I don''t understand something. I verified

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 different servers. So, this resource

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.

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

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

Has anyone successfully setup a shorewall Ucarp solution?

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

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, except I write one. UCARP has the disadvantage that

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

Hello List: Recently our shorewall FW server went dead (PS failure) & 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''

>From the DeveloperPolicy.html document I gathered I need to send a patch to this list (which I did); could you clarify if I misunderstood it? The second patch is really trivial and I think it's worth applying - it seems like a typo by someone who tested on MSVC 11 but not 10; or maybe my local instance of MSVC10 is somehow deficient, of course. The first patch is adding MSVC-specific

In order to get llvm to compile on Windows with MSVC 10, I have to disable inline on utostr to avoid internal compiler failure, and disable _xgetbv call in OsSupportsAVX because it's only defined in MSVC 2012 compiler. The first patch (noinline) is known for many months now. I'm a casual llvm user, and don't know the proper channels to go through to submit a patch. Could someone tell

Hi All, I'm playing with KVM in order to adopt the technology for dev / testing purposes. Installing RHEL5 from ISO images works ok, no problems with installation. The problem occurs with PXE boot - it is simply doesn't try to do PXE boot, according to what I can see: Booting from Hard Disk... Boot from Hard Disk failed: not a bootable disk FATAL: No bootable device. _ I have: CentOS
