Hi all,
I've uploaded it via github - https://github.com/waipeng/nfsceph. Standard disclaimer applies. :)
Actually #3 is a novel idea, I have not thought of it. Thinking about the difference just off the top of my head though, comparatively, #3 will have
Actually #3 is a novel idea, I have not thought of it. Thinking about the difference just off the top of my head though, comparatively, #3 will have
1) more overheads (because of the additional VM)
2) Can't grow once you reach the hard limit of 14TB, and if you have multiple of such machines, then fragmentation becomes a problem
3) might have the risk of 14TB partition corruption wiping out all your shares
4) not as easy as HA. Although I have not worked HA into NFSCEPH yet, it should be doable by drdb-ing the NFS data directory, or any other techniques that people use for redundant NFS servers.

Yip,I went to the link. Where can the script ( nfsceph) be downloaded? How's the robustness and performance of this technique? (That is, is there are any reason to believe that it would more/less robust and/or performant than option #3 mentioned in the original thread?)--On Fri, Nov 15, 2013 at 1:57 AM, YIP Wai Peng <yipwp@xxxxxxxxxxxxxxx> wrote:

1) nfs over rbd (http://www.sebastien-han.fr/blog/2012/07/06/nfs-over-rbd/)We are now running this - basically an intermediate/gateway node that mounts ceph rbd objects and exports them as NFS. http://waipeng.wordpress.com/2013/11/12/nfsceph/
