What does "potential for reliability" even mean? Even Lustre, which you malign and I have maligned even more, has potential for reliability if they just fix a few hundred egregious design flaws.
I haven't had a chance to run it. I also don't have clear data on it's userbase. I just know it's been used in supercomputing centers for a while doing large jobs fast over fast WAN's. So, potentially reliable if I see more users telling me it is in various situations.
