Did anyone use mirrored glusterfs for storing virtual machine images, like qcow2? Virtual machine images are typically large, ranging from a few GBs to hundreds of GBs. Usually, they are mirrored with things like DRBD. I was wondering if anyone uses gluster (in mirrored mode) for storing images of running virtual machines? How resilient can we expect gluster to be when: 1) the host writing to glusterfs crashes, 2) one of glusterfs mirrors crashes. Anyone with some experience here? -- Tomasz Chmielewski http://wpkg.org
