Subject: [PATCH 00/21] Btrfs: restriper
Date: Fri, 6 Jan 2012 16:30:48 +0200 [thread overview]
Message-ID: <1325860269-15013-1-git-send-email-idryomov@gmail.com> (raw)
Hello,
This is a respin of restriper patch series which adds an initial
implementation of restriper (it's a clever name for relocation framework
that allows to do selective profile changing and selective balancing
with some goodies like pausing/resuming and reporting progress to the
user). See userspace cover patch for usage examples.
Changes from posted RFC include minor fixes to address received feedback
and some minor fixes of my own: improved inline comments, pause and
cancelling enhancements to eliminate race conditions, a better
validation of user input, some error reporting and error handling fixes.
Also I did s/restripe/balance to not introduce yet another term into
btrfs. So nothing major, but the diff got quite large because of the
rename and some code movements.
The series is on top of 3.1 + for-linus, available at:
git://github.com/idryomov/btrfs-unstable.git restriper
Thanks,
Ilya
