So, I'd like to hear your stories. What's worked for you? What hasn't worked? What would you consider the pain points with using btrfs?
Using `rsync --inplace` to update files that have shared extents (like, in snapshots) leads to what seems to be terrible fragmentation — so much that said rsync command progresses at considerably reduced speed, noticable when updating "big" files where there is a chance to look at the rsync -P progress.
I don't think that autodefrag mount option could improve that significantly, though it could have a slightly positive effect in some cases. If a block is being rewritten, the surrounding block up to limit 64k are read and rewritten as well moved to a new location. david -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
