* btrfs-progs: document snapshot unaware defragChristoph Anton Mitterer2016-01-12
| | | | | | | | | | | | | In btrfs-filesystem(8), improved the documentation of snapshot unaware defragmentation and included the exact kernel version numbers being affected as well as the possible effects. No longer use the word "unlink" which is easily understood as "deleting a file". Moved the warning more to the beginning of "defragment" subcommand's documentation where it's more visible to readers. Added the same warning to the "autodefrag" option of btrfs-mount(5). Signed-off-by: Christoph Anton Mitterer <mail@christoph.anton.mitterer.name>

* Btrfs-progs: Do not force mixed block group creation unless '-M' option is ↵Chandan Rajendra2015-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | specified When creating small Btrfs filesystem instances (i.e. filesystem size <= 1GiB), mkfs.btrfs fails if both sectorsize and nodesize are specified on the command line and sectorsize != nodesize, since mixed block groups involves both data and metadata blocks sharing the same block group. This is an incorrect behavior when '-M' option isn't specified on the command line. This commit makes optional the creation of mixed block groups i.e. Mixed block groups are created only when -M option is specified on the command line. Since we now allow small filesystem instances with sectorsize != nodesize to be created, we can end up in the following situation, [root@localhost ~]# mkfs.btrfs -f -n 65536 /dev/loop0 btrfs-progs v3.19-rc2-405-g976307c See http://btrfs.wiki.kernel.org for more information.

This is because of things like large metadata block size, DUP mode used for metadata and global reservation consuming space. Also, large nodesize does not make sense on small filesystems, hence this should not be an issue.

* Btrfs-progs: add feature to get mininum size for resizing a fs/deviceFilipe Manana2015-08-31
| | | | | | | | | | | | | | | | | | | Currently there is not way for a user to know what is the minimum size a device of a btrfs filesystem can be resized to. Sometimes the value of total allocated space (sum of all allocated chunks/device extents), which can be parsed from 'btrfs filesystem show' and 'btrfs filesystem usage', works as the minimum size, but sometimes it does not, namely when device extents have to relocated to holes (unallocated space) within the new size of the device (the total allocated space sum). This change adds the ability to reliably compute such minimum value and extents 'btrfs filesystem resize' with the following syntax to get such value: btrfs filesystem resize [devid:]get_min_size Signed-off-by: Filipe Manana <fdmanana@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
