* btrfsck: add code to rebuild extent recordsChris Mason2012-02-07
| | | | | | | This also includes a new --repair btrfsck option. For now it can only fix errors in the extent allocation tree. Signed-off-by: Chris Mason <chris.mason@oracle.com>
* btrfs-corrupt-block: add -e option to corrupt the extent recordChris Mason2012-02-07
| | | | | | This will zero out the extent allocation tree records for the extent. Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Allow extent_buffers to use more ramChris Mason2012-02-06
| | | | | | | | This changes free_some_buffers (called each time we allocate an extent buffer) to allow a higher hard limit on the number of extent buffers in use. Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Add open_ctree_fs_info for partial FS opensChris Mason2012-02-05
| | | | | | | | | | fsck needs to be able to open a damaged FS, which means open_ctree needs to be able to return a damaged FS. This adds a new open_ctree_fs_info which can be used to open any and all roots that are valid. btrfs-debug-tree is changed to use it. Signed-off-by: Chris Mason <chris.mason@oracle.com>

| * Btrfs-progs: fall back to the v1 ioctl if the new balance ioctl failsChris Mason2012-02-05

| * Btrfs-progs: switch all existing commands to a new parserIlya Dryomov2012-02-03
| | | | | | | | | | | | | | The new infrastructure offloads checking number of arguments passed to a command to individual command handlers. Fix them up accordingly. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
| * Btrfs-progs: implement new subcommand parserIlya Dryomov2012-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This completely replaces the existing subcommand infrastructure, which is not flexible enough to accomodate our needs. Instead of a global command table we now have per-level tables and command group handlers, which allows command-group-specific handling of options and subcommands. The new parser exports a clear interface and gets out of the way - all control over how matching is done is passed to commands and command group handlers. One side effect of this is that command implementors have to check the number of arguments themselves - patch to fix up all existing commands follows. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
| * Btrfs-progs: rearrange files in the repoIlya Dryomov2012-02-03
| | | | | | | | | | | | | | Separate every command group into its own file (cmds_<group>.c) and rearrange includes. Remove btrfs_cmds.c. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
* | Btrfs-progs: change the way mkfs picks raid profilesIlya Dryomov2011-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently mkfs in response to mkfs.btrfs -d raid10 dev1 dev2 instead of telling "you can't do that" creates a SINGLE on two devices, and only rebalance can transform it to raid0. Generally, it never warns users about decisions it makes and it's not at all obvious which profile it picks when. Fix this by checking the number of effective devices and reporting back if the specified profile is impossible to create. Do not create FS in case invalid profile was given.

* Scan the devices listed in /proc/partitionsGoffredo Baroncelli2011-10-25
| | | | | | | | | | | During the commands: - btrfs filesystem show - btrfs device scan the devices "scanned" are extracted from /proc/partitions. This should avoid to scan devices not suitable for a btrfs filesystem like cdrom and floppy or to scan not existant devices. The old behavior (scan all the block devices under /dev) may be forced passing the "--all-devices" switch.
