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

Hi Chris, this serie of patches updated the command "btrfs filesystem df". I update this command because it is not so easy to get the information about the disk usage from the command "fi df" and "fi show". This patch was the result of some discussions on the btrfs mailing list. Many thanks to all the contributors. From the man page (see 2nd patch): [...] The

This reverts commit 5500cdbe14d7435e04f66ff3cfb8ecd8b8e44ebf. We had numerous reports of premature ENOSPC that were bisected to this patch. Reverting will not break things but a warning in ''use_block_rsv'' may show up in the syslog. There''s no alternative fix in sight and the ENOSPC problem affects all 3.3 btrfs users during normal filesystem use. CC:

Hi, Question is pretty simple: "How to change node size and leaf size on previously created partition?" Now, I know what most people will say: "you should''ve be smarter while typing mkfs.btrfs". Well, I''m intending to convert in place ext4 partition but there seems to be no option for leaf and node size in this tool. If it''s not possible I guess

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
