Note that xfs and btrfs have delayed allocations/reservations or so, which cause the filesystem logic to reserve a large region for the expected journal/data/something items (I have observed values around the order of 500 to 4096MB - `df` will indicate it), and will only release it after it is synced to disk. In other words, a 2 GB disk may not be enough to hold all the temp things that xfs and btrfs want to use. You can of course mount with -o sync, at a given penalty. Heck, btrfs considers 1 GB to be really really small; there's a -M mixed option to mkfs.btrfs just for it (though it is not one that has helped in my experiments with such small volumes). -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
