45 * mkfs.btrfs --data dup
47 People asked about duplicating data on a single device for a long time. There
48 are no technical obstacles preventing that, so it got enabled with a warning
49 about potential dangers when the device will not do the duplicated copies. See
50 mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
52 * support balance filters added/enhanced in linux 4.4
53 * usage=min..max -- enhanced to take range
54 * stripes=min..max -- new, filter by stripes for raid0/10/5/6
55 * limit=min..max -- enhanced to take range
56 Note: due to backward compatibility, the range maximum for 'usage' is not
57 inclusive as for the others, to keep the same behaviour as usage=N .
59 * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
60 * error messages updates, rewordings -- some fstests may break due to that
61 * added support for free-space-tree implementation of space cache -- this
62 requires kernel 4.5 and is not recommended for non-developers yet

142 btrfs-progs-4.2.3 (2015-10-19)

159 this leads to mkfs failure for example due to "no free blocks
161 * for other nodesizes, if the end of the metadata block was 64k
162 aligned, it was incorrectly reported by fsck
