Comments on Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10

Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10 This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running Ubuntu 11.10) with GlusterFS. The client system (Ubuntu 11.10 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.

Thanks for this series of articles.

I have been testing this with 4 virtual servers (ubuntu 11.10 server) running in VirtualBox, but I couldn't mout the glusterfs volumen.

I had to set allow-insecure to true:

gluster volume set testvol allow-insecure true

And them I just could mount the volumen and write on it.

On the logs apeared the following message:

[socket.c:1494:__socket_proto_state_machine] 0-socket.management: reading from socket failed.Error (Transport endpoint is not connected)
