In redhat clustering (HA), Due to lack of knowledge on clustering, If the master node fails the virtual ip will be shifted to slave and the second node becomes the master, how the shifting of virtual ip happens, correct me if i am wrong? (ASssumes that vip is assigned to active node), in real time how this is implemented?
I have been running ubuntu for 7-8 years now but I don't claim to be great. I get by fine. Recently I managed to use No-ip (my IP is dynamic) to get remote access to my home computer via remote desktop sharing, some port forwarding, etc. Works great.
This prompted me to want to setup my own home server and use something like the WD-TV live box for my TV to stream files on my home network.
I'm in the process of configuring a sort-of Beowulf cluster, the major difference being that I want to be able to add nodes from any network. Because of this I can't run DHCP on the server to inventory all the nodes.
New nodes would run a package or script to configure SSH, MPI, NFS and the like. During installation they'll require the IP address of the server.
I am trying to do the two node clustering with serviceguard package in redhat 5 and I am following this link http ://pbraun.nethence.com/doc/sysutils/mcsg.html
Here They are mentioning 10.1.1 for network use and 10.1.2 and 10.1.3 for HeartBeat use,
I have a doubt, How to make a heartbeat network, Is there any procedure,
Shall I use 192.168.0 for network use and 192.168.10 for HeartBeat use
I have been reviewing XtraDB clustering and produced a P.o.C.
We have just installed two Windows 2008R2 Enterprise machines with identical hardware. When running the cluster validation everything is ok.
I am attempting to setup a cluster, and I need to find the MAC addresses of the nodes I'm attempting to put on the cluster's network.
I do not have a way to view the node information locally, and my cluster setup is diskless/server centric.
I've been reading a lot, but got to no conclusion yet.
In the client PC, I installed remmina.
On the notebook I want to access remotely what server should I install?
This remote notebook is running ubuntu 10.04 still, and I want to view the same desktop as the local user is viewing, in order to solve problems she's facing.
The connection must be secure, using ssh tunnel or other method.
Background:
I using a computing cluster at work (4 slave nodes and 1 head node) that uses the SGE job scheduler. Recently we've been running jobs that do some heavy IO and it has been slowing down shell/vim usage (small IO, but we need it running smoothly 24/7).
