Hi List,
I`m trying to build a cluster storage with commodity hardware in a way that
the all the data would be on > 1 server. It should have the meet the
following requirements:
1) If one of the servers goes down, the cluster should continue to work with
rw access from all clients.
2) Clients that mount the storage should not be part of cluster (not export
any disk storage) - I have few servers with huge disks that I want to store
data on (currently 2 servers, maybe more in the future) and I want to
storethe data only on them, the rest of the server should just mount and use
that storage with the ability to continue operation if one of the two storage
servers goes down.
3) More servers should be able to join the cluster and at given point,
expanding the total size of the cluster, hopefully without rebuilding the
storage.
4) Load balance is not a issue - all the load can go to one of the two storage
servers (although its better to be balanced), the main goal is to have
redundant storage
Does ocfs2 meet these requirements? I read few howtos but none of them
mentioned my second requirement (only some of the servers to hold the data).
Are there any specific steps to do to accomplish (2) and (3)?
I`m using Ubuntu 6.06 on x86.
Thanks!
