I've installed Centos on 4 Virtual Machines. 1 is set up as the Conga/Luci server to configure the nodes, and the other 3 nodes are set up with ricii.

Great.

They are a cluster. It says so in the Centos Cluster Manager(Conga)

I want to make a fileshare on this cluster, that is accessible from another machine. One that is fault tolerant and always available.

Please point me in the right direction, or to an article explaining how to do this.. on Centos using Conga. A step-by-step guide would be fine. I would much rather have an explanation of what is being done though.

Ps: I've already went through the Red-Hat examples 2/3 times, and have not had any luck yet. I have it printed out, i've checked off each step as i've done it, and it simply does not work.

Need more details. Are you planning to use GFS as the filesystem or something else? What Red-Hat examples are you speaking of, can you point us to them? What doesn't work? Errors or more details get better answers or solutions.

I want a high availability NFS server cluster. 5 nodes, each with hard drives... somehow offering NFS, and failing over if it breaks.

Red hat has an example -- but it uses common shared storage. Which to me is a single point of failure and kind of pointless. If I had 5 computers, each with a hard drive, there should be a way to cluster them out, use a shared IP or something... offer up NFS, failover if one dies. That sort of thing.

Hi,

I know I'm late to the party, but have you considered DRBD?

Basically, my understanding is that you want to have data redundancy across the networked computers to form an HA, right? Well, DRBD , from the site, can be thought of as Network based RAID 1.
