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?
