Gluster users - Mar 2011 - Question regarding redundancy on Glusterfs 3.1

Hello I am a bit confused.

I setup glustefs on a 4 node cluster setting up distribute replication.

On the client machine i install the glustefs client and setup the mount. The
mount point connects to the first server on the trusted storage pool.

So if this first server in the storage pool dies. How would the client
glustefs failover to another node. And how best to bring the cluster back to
its 4 node strength.

Your help is greatly appreciated.

Hi Hareem.

Please do a search on the mailing list using the term "ucarp", and
that will show you how some people have implemented virtual IP addresses and the
ucarp program to protect against the scenario that you have just described.

I do this on my own setup, and it works just fine.

The procedures for failing out a bad server node and then reintegrating it are
documented in the Administrators guide.

Thanks,

James Burnash, Unix Engineering
