Hi,
btrfs-progs 4.4 have been released.
User visible changes
--------------------
* mkfs.btrfs --data dup
People asked about duplicating data on a single device for a long time. There
are no technical obstacles preventing that, so it got enabled with a warning
about potential dangers when the device will not do the duplicated copies.
See mkfs.btrfs section 'DUP PROFILES ON A SINGLE DEVICE'.
* support balance filters added/enhanced in linux 4.4
* usage=min..max -- enhanced to take range
* stripes=min..max -- new, filter by stripes for raid0/10/5/6
* limit=min..max -- enhanced to take range
Due to backward compatibility, the range maximum for 'usage' is not inclusive
as for the others, to keep the same behaviour as usage=N .
* manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
* error messages updates, rewordings -- some fstests may break due to that
* added support for free-space-tree implementation of space cache
this requires kernel 4.5 and is not recommended for non-developers yet
Hi David,
Not sure if it's intended or just a small miss, in btrfs-progs ctree.h,
there is BTRFS_FEATURE_COMPAT_RO_FREE_SPACE_TREE, but
BTRFS_FEATURE_COMPAT_RO_SUPP is still 0, not including FREE_SPACE_TREE.
Is it intended as current btrfsck doesn't support to modify fs with new
free space cache tree?
Thanks,
Qu
* 'btrfs filesystem usage' works with mixed blockgroups
Other:
* installation to /usr/local -- this has unintentionally changed during
conversion to autotools in 3.19
* check: fix a false alert where extent record has wrong metadata flag
* improved stability on fuzzed/crafted images when reading sys array in
superblock
* build: the 'ar' tool is properly deteced during cross-compilation
* debug-tree: option -t understands ids for tree root and chnuk tree
* preparatory work for btrfs-convert rewrite
* sparse, gcc warning fixes
* more memory allocation failure handling
* cleanups ...
* more tests
Bugfixes:
* chunk recovery: fix floating point exception
* chunk recovery: endianity bugfix during rebuild
* mkfs with 64K pages and nodesize reported superblock checksum mismatch
* check: properly reset nlink of multi-linked file
Development cycle for 4.5
-------------------------
There are a few patchsets that did not make it to 4.4 and are currently
at the top of my list.
* feature compatibility of mkfs and kernel (Anand)
* convert rework (Qu) -- more reivew needed, the pending patches are
in branch foreign/qu/convert-rework
* delete device by id (Anand) -- the kernel support is required, I need
to look at the patches again
* improved btrfs check progress
There are a few more and I hope I'll get to them eventually. The bi-weekly
stable releases are supposed to be resumed with bugfixes or docs updates.
