Comments on High-Availability Storage With GlusterFS On Ubuntu 9.10 - Automatic File Replication (Mirror) Across Two Storage Servers
This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 9.10) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 9.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Zyrion Traverse allows creating service containers which can monitor application response times and correlate that with the underlying storage components which are relevant to that application using its Business Container technology. http://zyrion.com/solutions/server.php
Hi,
I dont see that you use the namespace directory in the configuration?
Is this really high available? I have a similar setup but any activity on a mounted partition hangs when one server is down.
I would really it to be replicated (later) if one server is down, but I dont think such a type exist?
i just started to configuring my first glusterfs storage and reading the documentation but it looks like your example is not really a haigh availability setup, in this and other glusterfs setups the client only writes to both nodes;
if one server node goes down and come back up at a later time who will replicate the missing data to it?
as i just found on the documentation the server nodes should be setup with 'glusterfs-volgen' and option raid1....
