similar to: Linux HA or Heartbeat IP address question

Hi all, I am new to Hearbeat so please be kind :) I also posted this on Linux-HA lists with no responses so I posted it here. I have successfully configure two machines to use heartbeat to cluster httpd. The two nodes are called etk-1 and etk-2. I am trying to configure another two machines to act as a separate cluster (on the same IP subnet). These two nodes are called radu-1 and radu-2.

Hi all, I am trying to mount images that I previously created with dd and the images have two partitions (swap and LVM). I use these images to house data for my Xen Guests. For some reason (possibly Kernel conflicts for paravirtualized domains) I am unable to boot my Guest images. Failing which I would like to mount the disk images and atleast get my data out of them. dd -o loop server.img

Hi all, First of all I am posting this on two lists for a reason, because the issue being reported by me could be because of a change delivered by a Kernel update or due to Xen. I have recently managed to update all Xen Guest domains running CentOS 5.3 to the latest bunch of updates + Kernel. My Xen host also runs the same CentOS 5.3 updated to all recent packages. The Guest images in concern

Hello all, I am using the c5-testing repo to fetch PHP 5.2.6 and related libraries, required for the LAMP apps that I want to use. php-mcrypt still seems to come from the extras repo and is version 5.1.6 and the php binary doesn't load this module. Any ideas on howto get php-mcrypt 5.2.6? Thanks. -- "The secret impresses no-one, the trick you use it for is everything" - Alfred

Hi all, Wondering if anyone knows of any tools I can run on my Dom0 to log various stats (like CPU usage, memory usage, etc) for each guest domain for analysis over a period of time? I can see that xentop displays that information anyway but would be nice to be able to present that information on a web based interface for day to day administration. Also any tools that send out email

Hi all, I am in a bit of a fix here, I have several Guests paravirtualized running on a Dom0 that is currently running the 2.6.18-92.1.22.el5xen Kernel. All my guests (administered by different people) have subsequently been updated to later versions of the kernel (namely 2.6.18-164.el5xen or 2.6.18-128.4.1.el5xen). Ones that are still running are using the Kernel 2.6.18-128.4.1.el5xen while

Hi We've got drbd going between 2 nodes:) ATM there is un-partitioned space on each node but (we think) they are syncing OK. It looks as though it has synced the whole partition (2GB) from the primary node 1 to the other node: node 1 smb1:/home/steve # cat /proc/drbd version: 8.4.4 (api:1/proto:86-101) GIT-hash: 3c1f46cb19993f98b22fdf7e18958c21ad75176d build by SuSE Build Service 1:

Hi all, We have 2 mail servers sitting behind linux-HA machines.The mail servers are currently running dovecot 1.0rc2. Looking to enable GSSAPI authentication, I exported krb keytabs for imap/node01.domain at REALM and imap/node02.domain at REALM for both mail servers. However, clients are connecting to mail.domain.com, which results in a mismatch as far as the keytab is concerned (and rightly

Hello, I'm setting up an active-passive Asterisk solution on Debian Jessie platforms. I'm using heartbeat package. As I'm not yet familiar with either systemd or heartbeat, I've got a couple of questions: 1. At the moment, I'm using /usr/share/heartbeat/hb_standby or /usr/share/heartbeat/hb_takeover scripts to both : - allocate "floating" IP addresses to active

Hello, I'm beginning to give up on making Linux-HA's heartbeat work for my environment (CentOS x86_64) and am wondering what other option have I got to help me: 1. Use IPVS to maintain a cluster of virtual servers, either master/slave or load-balanced. 2. Use DRBD in master/slave fashion to keep a home-grown application highly-available. The first thing I stumbled upon is RedHat Cluster

I've been bashing my head into a wall the past few days on this. I am trying to setup a Load Balanced MySQL Cluster. I can get the MySQL NDB Clusters working, but when I try to install the HA Load Balancers, I can't get past the step of the shared Virtual IP. I'm basing my sequence on HowToForge Guide written for Debain

Hi All, I currently have another thread open on squid authentication with Samba 4 and am going to try authenticating against kerberos instead of NTLM. According to the docs for the web filter I'm using, it's essential for Kerberos to be able to resolve reverse DNS so I've spent the last weekend trying to get this working. Various different documents and howtos exist but none of
