When rebooting from a crash, thus during log replay on 2.6.29-rc2,
btrfs_insert_dir_item caused an assertion failure [1]. The fs was
being mounted clear_cache on an SSD.
Probably it's not so easy to reproduce, but better to report it...

Allow the balancing of chunks where some part of the chunk lies within
the virtual (i.e. btrfs-internal) address range passed.

Add a filter for balancing which allows the selection of chunks with
data in the given byte range on any block device in the filesystem. On
its own, this filter is of little use, but when used with the devid
filter, it can be used to rebalance all chunks which lie on a part of
a specific device.
Hi, Chris,
Another iteration of the balance management patches. This includes
suggestions from David Sterba, who did a fairly comprehensive review
of the patch series on IRC. It also includes fixes for comments from
Josef, and Li Zefan. The only thing I've not included here is Li's
The main balance function has two loops which are functionally
identical in their looping mechanism, but which perform a different
operation on the chunks they loop over. To avoid repeating code more
than necessary, factor this loop out into a separate iterator function
which takes a function
The filtered balance ioctl provides a facility to perform a balance
operation on a subset of the chunks in the filesystem. This patch
implements the base ioctl for this operation, and one filter type.
The filter in this patch selects chunks on the basis of their chunk
flags field, and can select
Balance filter to take only chunks which have (or had) a stripe on the
given device. Useful if a device has been forcibly removed from the
filesystem, and the data from that device needs rebuilding.

There are a few places in btrfs where knowledge of the various
parameters of a replication type is needed. Factor this out into a
single function which can supply all the relevant information.

This patch adds an ioctl for cancelling a btrfs balance operation
mid-flight. The ioctl simply sets a flag, and the operation terminates
after the current block group move has completed.

Hi all,
I'd like to look into btrfs code and try some things, so I followed the
instructions on the wiki (link below) to setup git and get a dkms build
against my kernel. I'm using Ubuntu 10.10 with a 2.6.35 Kernel, which I
assume is too old. What version do I need?
Hi, Chris,
These patches form the userspace side of the balance management
work. This includes two patches to add one-off and polled monitoring,
a fork-to-background patch, and a sequence implementing the user
interface to handle the various types of balance filtering implemented
in the

Implement the userspace side of the balance filter for a range of
