Unfortunately nothing guarantees that the footprint of the filesystem
will stay bounded.
In other words, even if the number of blocks occupied by the
filesystem at any time is less than the capacity of the physical
device backing the sparse device, the total number of blocks ever
occupied by the f

I've noticed the same. I'm interested in researching the patterns the
filesystem puts down on a
Hello,
There seems to be a 256 MiB lower limit on device size : mkfs.btrfs
refuses to create a filesystem
on a device that is smaller than that.
I'm interested in using the btrfs RAID facility to provide redundancy
for an embedded system, but I can't afford
two 256 MiB partitions.
What are the s

That previous patch was against btrfs-next, this patch is against 3.4-rc6 if you
are on mainline. Thanks,
I tried your patch against mainline, after a few minutes I hit this bug.

Hello,
In the btrfs wiki
( https://btrfs.wiki.kernel.org/index.php/Btrfs_source_repositories ) it

In normal cases, we would not be allowed to do balance in RO mode.
However, when we're using a seeding device and adding another device to sprout,
things will change:
