similar to: GlusterFS failover with UCarp

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

hi! im trying to implement a role based authentication in my project, but im writing too many conditions, and i think thats not the right way to proceed. i have search in google, but there are a lot of plugins and "tutorials", and they are always not similar, so i dont understand them. please could someone help me? maybe with a easy authentication or with a good/nice tutorial?

Has anyone successfully setup a shorewall Ucarp solution?

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 just got the Rails Recipies and I''m looking the Recipe 17. class Person < ActiveRecord::Base has_many :addresses, :as => :addressable end class Company < ActiveRecord::Base has_many :addresses, :as => :addressable end class Address < ActiveRecord::Base belongs_to :addressable, :polymorphic => true end At the beggining I had some problems because

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 maintained in /etc/network/interfaces (Debian),

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

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.

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

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''

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, 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 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? Thanks, Christian -- you don''t need eyes to see

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

Hi there, Has anyone tried acts_as_ferret with Edge Rails and Mongrel? When I install the plugin to a project that has Edge Rails frozen, and the Mongrel gem installed, I can''t start the server. There''s no error, it just doesn''t start. I''ve used acts_as_ferret in the past with WEBrick, and stable Rails releases without a hitch. If I remove the

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

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

Hi Junaid, Sorry about the confusion, indeed I gave you the wrong output. So let's start to the beginning. I disabled quota and I reactivated it My configuration : Volume Name: venus Type: Distributed-Replicate Status: Started Number of Bricks: 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: ylal3020:/soft/venus Brick2: ylal3030:/soft/venus Brick3: yval1000:/soft/venus Brick4:

If you export two subvolumes of a btrfs filesystem, they will both be given the same uuid so lookups will be confused. blkid cannot differentiate the two, so we must use the fsid from statfs64 to identify the filesystem. We cannot tell if blkid or statfs is best without knowing internal details of the filesystem in question, so we need to encode specific knowledge of btrfs in mountd. This is
