Actually, most of my testing is done via VMWare. It works surprisingly well and is much cheaper than several Fibre Channel disks and controllers. Of course, for real world applications this would never work, but it is decent for testing. Some of the other guys are using a PC with the GNBD (our network block device) server, serving out a block device to a couple of laptops. Again, performance is not great (due to slow PCMCIA NICs, but it works. Of course, ideally you want a fast Fibre Channel array and several computers with Fibre Channel cards, and some of the testing is done with this, but I generally don't need that kind of test setup. (BTW, if you don't know what fibre channel is, check out http://www.sistina.com/gfs/howtos/fibrechannel_howto/index.html ) Basic testing can be done on a single node though. Just run the lock server on the same machine as the GFS partition, and run it through the paces. There is also a nolock locking module for this kind of testing, where you don't need a lock server (and no actual locking is done, so don't try this with multiple GFS machines on the same GFS file system, you will corrupt your data.)
