...to be had. I think I finally have a hold on what the problem is, it only happens with Metadata writes, and happens _very_ infrequently. What has to happen is we have to allocate have allocated out of the first logical byte on the disk, which would set last_alloc to first_logical_byte(root, 0), so search_start == orig_search_start. We then need to allocate for normal metadata, so BTRFS_BLOCK_GROUP_METADATA | BTRFS_BLOCK_GROUP_DUP. We will do a block lookup for the given search_start, block_group_bits() won''t match and we''ll go to choose another block group. However because search_sta...

Here are 3 patches to avoid undesired aborts of mkfs.btrfs. These are based on top of Chris''s btrfs-progs.git: git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git Thanks, H.Seto Hidetoshi Seto (3): btrfs-progs: error if device for mkfs is too small btrfs-progs: error if device have no space to make primary chunks btrfs-progs: calculate available

Hello, This patch adds a new parameter 'full_scan' to 'find_search_start', thereby 'find_search_start' can know whether 'find_free_extent' is in full scan phrase. I feel that 'find_search_start' should skip calling 'btrfs_find_block_group' when 'find_free_extent' is in full scan phrase. In my test on a 2GB volume, Oops occurs...

Hello, This patch fixes a problem where we end up seeking too much when *last_ptr is valid. This happens because btrfs_lookup_first_block_group only returns a block group that starts on or after the given search start, so if the search_start is in the middle of a block group it will return the block group after the given search_start, which is suboptimal. This patch fixes that by doing a btrfs_lookup_block_group, which will return the block group that contains the given search start. If we fail to find a block group, we fall back on...

In a multi device setup, the chunk allocator currently always allocates chunks on the devices in the same order. This leads to a very uneven distribution, especially with RAID1 or RAID10 and an uneven number of devices. This patch always sorts the devices before allocating, and allocates the stripes on the devices with the most available space, as long as there is enough space available. In a low

Just a quick update, I''ve dropped the hashing stuff in favor of doing a memcmp in the kernel to make sure the data is still the same. The thing that takes a while is reading the data up from disk, so doing a memcmp of the entire buffer isn''t that big of a deal, not to mention there''s a possiblity for malicious users if there is a problem with the hashing algorithms we

If we have particularly full nodes, we could call btrfs_node_blockptr up to 32 times, which is 32 pairs of kmap/kunmap, which _sucks_. So go ahead and map the extent buffer while we look for readahead targets.
