Reflink is not yet on by default upstream - i.e. the upstream development community has not yet deemed it ready for widespread public use. Indeed, several data corruption bugs in clone_range & friends have recently been found in the kernel, and more work in that area is ongoing. So it's a balancing act. I'm still hesitant to unleash this on every Fedora user just yet, because as a filesystem developer my version of the Hippocratic Oath is "First Lose No Data." If you'd like to help push this forward, encourage i.e. the Podman community to actually test this stuff heavily and report back, whether it's success or failure. More data points help, that's the whole oint of the semi-slow rollout from experimental to optional to default. It's there and available for use, please test it and give us more confidence. Thanks, -Eric Understood, but by the same token, if no one ever turns on the feature, does the feature really exists. :^) I would think turning it on in Rawhide for a few months and then pulling it out if it causes problems. My biggest issue with it, is I can not toggle it on in the graphical installer. So I end up having to deal with it at the mkfs level, and I really do not want to document how to do this at that level. From the better-late-than-never department, reflink is now on by default in xfsprogs-5.1.0 pushed to rawhide. |
