    text
    copied!<p>To serve millions of files out of a single directory, being able to connect to a drive from hundreds of endpoints, and for some other reasons (to avoid gluster/nfs/all fs based networking solutions), I want to evaluate the possibility of making a filesystem that's based on a mongodb (or any other).</p> <p>Basically, it works like fusefs, every single file is kept in mongo gridfs. In theory, I do,</p> <p><code>mount mongodbfs /mountPoint mongodb://localhost</code></p> <p>then when i say <code>touch /mountPoint/test.txt</code> this file is inserted into mongodb. This FS will also store uid/gid and perms with the file, we can throw hundreds of servers to it, and no <code>useradd</code> will be necessary. I'm not thinking to include all the features of FS, just the ones we need.</p> <p>My question is, how do I start my quest in finding resources, books, links, people, developers who'd help me implement this? at least a proof of concept. Is it feasible? What should I expect as a timeline for such undertaking?</p> <p>Please only think about gazillion small files and folders.</p> <p>ps: after a few days of research i think this is the direction i'm heading <a href="http://www.ibm.com/developerworks/library/l-sc12.html" rel="nofollow">http://www.ibm.com/developerworks/library/l-sc12.html</a> http://www.flipcode.com/archives/Programming_a_Virtual_File_System-Part_I.shtml</p> <p>ps2: i'm aware of the difficulty of this undertaking. however we're willing to set aside a serious budget and willing to form a serious team implementing it - only after we make sure that this isn't a black hole (thus the question).</p>
