* btrfs-progs: check: enhanced progress indicatorSt├ęphane Lesimple2018-08-06
| | | | | | | | | | | | | | | | | | | | | | | | We reuse the task_position enum and task_ctx struct of the original progress indicator, adding more values and fields for our needs. Then add hooks in all steps of the check to properly record progress. Here's how the output looks like on a 22 Tb 5-disk RAID1 FS: Opening filesystem to check... Checking filesystem on /dev/mapper/luks-ST10000VN0004-XXXXXXXX UUID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx [1/7] checking extents (0:20:21 elapsed, 950958 items checked) [2/7] checking root items (0:01:29 elapsed, 15121 items checked) [3/7] checking free space cache (0:00:11 elapsed, 4928 items checked) [4/7] checking fs roots (0:51:31 elapsed, 600892 items checked) [5/7] checking csums (0:14:35 elapsed, 754522 items checked) [6/7] checking root refs (0:00:00 elapsed, 232 items checked) [7/7] checking quota groups skipped (not enabled on this FS) found 5286458060800 bytes used, no error found Signed-off-by: St├ęphane Lesimple <stephane_btrfs@lesimple.fr> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: check: lowmem: exclude extents of metadata blocksSu Yue2018-06-07
| | | | | | | | | | | | | | | | | | | | Commit d17d6663c99c ("btrfs-progs: lowmem check: Fix regression which screws up extent allocator") removes pin_metadata_blocks() from lowmem repair. So we have to find another way to exclude extents which should be occupied by existing tree blocks. Modify pin_down_tree_blocks() and rename it to traverse_tree_blocks for sharing code with new function exclude_metadata_blocks(). * exclude_metadata_blocks() traverses and marks extents of all tree blocks dirty in fs_info->excluded_extents. * cleanup_excluded_extents() is responsible for cleanup. Export them to mode-common.h since they will be used both in original and lowmem modes. Signed-off-by: Su Yue <suy.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: check: move pin_down_tree_blocks to mode-common.cSu Yue2018-06-07
| | | | | | | | | Move pin_down_tree_blocks from main.c to mode-common.c for further patches. And export pin_metadata_blocks to mode-common.h. Signed-off-by: Su Yue <suy.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>
* Btrfs-progs: check, fix false error reports for shared prealloc extentsFilipe Manana2018-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under some cases the filesystem checker reports an error when it finds checksum items for an extent that is referenced by an inode as a prealloc extent. Such cases are not an error when the extent is actually shared (was cloned/reflinked) with other inodes and was written through one of those other inodes. Example: $ mkfs.btrfs -f /dev/sdb $ mount /dev/sdb /mnt $ touch /mnt/foo $ xfs_io -c "falloc 0 256K" /mnt/foo $ sync $ xfs_io -c "pwrite -S 0xab 0 256K" /mnt/foo $ touch /mnt/bar $ xfs_io -c "reflink /mnt/foo 0 0 256K" /mnt/bar $ xfs_io -c "fsync" /mnt/bar <power fail> $ mount /dev/sdb /mnt $ umount /mnt $ btrfs check /dev/sdc Checking filesystem on /dev/sdb UUID: 52d3006e-ee3b-40eb-aa21-e56253a03d39 checking extents checking free space cache checking fs roots root 5 inode 257 errors 800, odd csum item ERROR: errors found in fs roots found 688128 bytes used, error(s) found total csum bytes: 256 total tree bytes: 163840 total fs tree bytes: 65536 total extent tree bytes: 16384 btree space waste bytes: 138819 file data blocks allocated: 10747904 referenced 10747904 $ echo $? 1 So teach check to not report such cases as errors by checking if the extent is shared with other inodes and if so, consider it an error the existence of checksum items only if all those other inodes are referencing the extent as a prealloc extent. This case can be hit often when running the generic/475 testcase from fstests. A test case will follow in a separate patch.
