* Btrfs image toolYan Zheng2008-11-20
| | | | | | | | | This patch adds btrfs image tool. The image tool is a debugging tool that creates/restores btrfs metadump image. Signed-off-by: Yan Zheng <zheng.yan@oracle.com>
* update btrfs-progs for seed device supportYan Zheng2008-11-18
| | | | | | | | | | | | This patch does the following: 1) Update device management code to match the kernel code. 2) Allocator fixes. 3) Add a program called btrfstune to set/clear the SEEDING super block flags.
* Avoid tree of tree root cow when committing a clean FSChris Mason2008-10-30
| | | | | | | | | | | | | The root node generation number code made commit_tree_root look like the kernel code. It forces a cow of the tree of tree roots even when the FS hasn't changed. This causes errors during fsck and other readonly operations. This adds a check to see if commit_tree_root is going to trigger writes to the tree of tree roots, and bails if none are pending.

* Add root tree pointer transaction idsYan Zheng2008-10-29
| | | | | | | | | | This patch adds transaction IDs to root tree pointers. Transaction IDs in tree pointers are compared with the generation numbers in block headers when reading root blocks of trees. This can detect some types of IO errors. Signed-off-by: Yan Zheng <zheng.yan@oracle.com>

* Update the Ext3 converterChris Mason2008-04-22
| | | | | | | | | | | The main changes in this patch are adding chunk handing and data relocation ability. In the last step of conversion, the converter relocates data in system chunk and move chunk tree into system chunk. In the rollback process, the converter remove chunk tree from system chunk and copy data back. Regards YZ ---
* Add a command to show all of the btrfs filesystems on the box (btrfs-show)Chris Mason2008-04-22

* Add chunk uuids and update multi-device back referencesChris Mason2008-04-15
| | | | | | | | | | | | | | | | | | Block headers now store the chunk tree uuid Chunk items records the device uuid for each stripes Device extent items record better back refs to the chunk tree Block groups record better back refs to the chunk tree The chunk tree format has also changed. The objectid of BTRFS_CHUNK_ITEM_KEY used to be the logical offset of the chunk. Now it is a chunk tree id, with the logical offset being stored in the offset field of the key. This allows a single chunk tree to record multiple logical address spaces, upping the number of bytes indexed by a chunk tree from 2^64 to 2^128.

* Recow all roots at the end of mkfsChris Mason2008-04-04
| | | | | | The mkfs code bootstraps the filesystem on a single device. Once the raid block groups are setup, it needs to recow all of the blocks so that each tree is properly allocated.

* btrfs-progs: Fix printf format casting errorsAlex Chiang2008-04-01
| | | | | | | | | | | We get lots of warnings of the flavor: utils.c:441: warning: format '%Lu' expects type 'long long unsigned int' but argument 2 has type 'u64' And thanks to -Werror, the build fails. Clean up these printfs by properly casting the arg to the format specified. Signed-off-by: Alex Chiang <achiang@hp.com>

* Add rollback support for the converterYan2008-01-08
| | | | | | This patch adds rollback support for the converter, the converter can roll back a conversion if the image file haven't been modified. In addition, I rearrange some codes in convert.c and add a few comments.

| | | | | This patch adds customized find_free_extent support to btrfs-progs, the conversion program requires this.
