In the previous section we presented a convenient way to deploy a shared storage using NFS. For better transactions performance, you could deploy MooseFS instead.
MooseFS (Moose File System) is a shared file system ; it implements the same rough concepts of shared storage solutions - such as Ceph, Lustre or even GlusterFS.
Main concepts
A metadata server (MDS), also called master server, which manages the file repartition, their access and the namespace.
A metalogger server (MLS) which backs up the MDS logs, including, objects, chunks, sessions and object metadata
A chunk server (CSS) which store the data as chunks and replicate them across the chunkservers
A client, which talks with the MDS and interact with the CSS. MooseFS clients manage MooseFS filesystem using FUSE
For more informations, please see the Official project website
Our setup will be made the following way :
Two compute nodes running both MooseFS chunkserver and client services.
One MooseFS master server, running the metadata service.
One MooseFS slave server, running the metalogger service.
For that particular walkthrough, we will use the following network schema :
10.0.10.15for the MooseFS metadata server admin IP10.0.10.16for the MooseFS metadata server main IP10.0.10.17for the MooseFS metalogger server admin IP10.0.10.18for the MooseFS metalogger server main IP10.0.10.19for the MooseFS first chunkserver IP10.0.10.20for the MooseFS second chunkserver IP
