   @dragnucs Maybe you are intested in distributed filesystems like GlusterFS. IIRC @steve once wrote about #GlusterFS & !RaspberryPi

     @dragnucs Some years ago I played with a #cluster of 3 PCs and the #OpenMosix live cd. http://qttr.at/ma5

     @dragnucs With OpenMosix you could start processes on the master & it would move them to other hosts → useful for usecases w/many processes

     @dragnucs It's difficult to say if you'll have a gain in performance… I hope your boards have gigabit ethernet.

     @lnxw48 with OpenMosix only the master would need a hdd. The others would boot+run from network/nfs. You're still right w/electricity though

     @dragnucs That's PCIexpress. Do you really have a board with PCIExpress that doesnt have SATA?

     @dragnucs I don't what load to expect from your Owncloud usecase but maybe consider !RaspberryPi 2 or #Odroid U3 (4x1.7GHz ARM)

     @dragnucs the RaspberryPi's runs at about 5 Watt,whereas three pentium4 PCs may easily need about 300 Watt and will make you poor in Germany

     @dragnucs ok, then you could go for the SATA card. Or, what about a 32 GB usb pen drive? Slow for writing, but reading speed may be ok

     @dragnucs OK. Another idea (if electricity doesn't matter): connect more disks to the other board and mount them via NFS on the webserver pc

     @dragnucs … (disregard my last idea, exchanging a board to a sata card may be the better plan, unless you'd like to keep the board)

     @dragnucs just using board #2 as a fileserver and transparently mount at /var/www/owncload/…/anywhere might be less hazzle (and less fun ;-)

     @dragnucs OpenMosix didn't work that way. Individual processes + their process memory were moved to another node transparently, if necessary

     @dragnucs #beowulf might be similar, because network speed is much slower than ram speed,so you need to minimise network traffic btwn nodes

     @der so a pizzabox is actually an individual network computer, just without things like own mass-storage?

     @dragnucs if you're interested in cluster computing I encourage you to play with OpenMosix livecd (old,but maybe there's a successor) #fun

     @der if you have 10 of these servers at 16 GB RAM each,can you use Xen to create 1 VM w/160 GB RAM? (even if slow) quitter.se/notice/3503702

     • Falk Duebbert
     @der sounds a bit like OpenMosix. You start a process at the master node and it would move the process+its memory to a less busy other node

     @der I know the HP DL380G5. Nice machine, but they installed Windows 2008 SBS on it. What a waste of resources.

     @der the numbers were just examples. If you have host A with x GB RAM & host B with y GB RAM, can you create a Xen VM with x+y GB RAM?

     @dragnucs If there is such a system, it will be slow. Transferring process memory between hosts will be at least as slow as disk swap. @der

     @dragnucs at least with processes with large process memory,like browsers, virtualizers,etc. Unless you have special (non-consumer) hardware

     @mcscx I run GlusterFS on my main server. Never did get around to trying it on an RPi.

     @steve so that would be without redundancy, the files are located only on the main server, like with an NFS server?

     @mcscx I run a mirror setup on my system, so I have 6TB total but 3 of it mirrors the other 3. Otherwise, it is then available to all systems in the house like an NFS mount.

     @mcscx Oh, and I forgot to say that indeed a single server provides the filesystem. I could have redundant backup servers if I setup other computers in the house each with their own mirror of the original, each capable of being mounted by clients.
