Hi Btrfs-List,
me and a friend have been using Btrfs on an Atom based home backup
server (Arch Linux) for the past 1 1/2 years or so running on 2 1 TB
drives (with a few gigabyte of the first drive used for / so it's a
bit below 2 TB) and it has been running quite nicely.
However a few days ago w

Point taken. So how's the b

Scrub used to be coded for nodesize == leafsize == sectorsize == PAGE_SIZE.
This is now changed to support sizes for nodesize and leafsize which are
N * PAGE_SIZE.

Scrub used to be coded for nodesize == leafsize == sectorsize == PAGE_SIZE.
This is now changed to support nodesize == leafsize == N * PAGE_SIZE.
The "Btrfs: fix scrub statistics report" patch that I sent on 2/10/2012
is also superseeded by this patch. This new patch includes similar
functionality
Readahead already has a define for the max number of mirrors. Scrub
needs such a define now, the rest of the code will need something
like this soon. Therefore the define was added to ctree.h and removed
from the readahead code.
