* 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: Make btrfs check return error for qgroup mismatchQu Wenruo2018-06-07
| | | | | | | | | | | | | | | Current btrfs-check will check qgroup consistency, but even when it finds something wrong, the return value is still 0. Fix it by allowing report_qgroups() to return int to indicate qgroup mismatch, and also add extra logic to return no error if qgroup repair is successful. Without this patch, fstests can't detect qgroup corruption by its fsck alone. Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: check: write corrected qgroup info to diskMark Fasheh2016-07-13
| | | | | | | | | | | | | | | | Now that we can verify all qgroups, we can write the corrected qgroups out to disk when '--repair' is specified. The qgroup status item is also updated to clear any out-of-date state. The repair_ functions were modeled after the inode repair code in cmds-check.c. I also renamed the 'scan' member of qgroup_status_item to 'rescan' in order to keep consistency with the kernel. Testing this was easy, I just reproduced qgroup inconsistencies via the usual routes and had btrfsck fix them.

* btrfs-progs: Fix return value bug of qgroups checkQu Wenruo2016-05-02
| | | | | | | | | | | Before this patch, although btrfsck will check qgroups if quota is enabled, it always return 0 even qgroup numbers are corrupted. Fix it by allowing return value from report_qgroups function (formally defined as print_qgroup_difference).

* btrfs-progs: show extent state for a subvolumeMark Fasheh2014-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The qgroup verification code can trivially be extended to provide extended information on the extents which a subvolume root references. Along with qgroup-verify, I have found this tool to be invaluable when tracking down extent references. The patch adds a switch to the check subcommand '--subvol-extents' which takes as args a single subvolume id. When run with the switch, we'll print out each extent that the subvolume references. The extent printout gives standard extent info you would expect along with information on which other roots reference it. Sample output follows - this is a few lines from a run on a subvolume I've been testing qgroup changes on: Print extent state for subvolume 281 on /dev/vdb2 UUID: 8203ca66-9858-4e3f-b447-5bbaacf79c02 Offset Len Root Refs Roots 12582912 20480 12 257 279 280 281 282 283 284 285 286 287 288 289 12603392 8192 12 257 279 280 281 282 283 284 285 286 287 288 289 12611584 12288 12 257 279 280 281 282 283 284 285 286 287 288 289 <snip a bunch of extents to show some variety> 124583936 16384 4 281 282 283 280 125075456 16384 4 280 281 282 283 126255104 16384 11 257 280 281 282 283 284 285 286 287 288 289 4763508736 4096 3 279 280 281 In case it wasn't clear, this applies on top of my qgroup verify patch: "btrfs-progs: add quota group verify code" A branch with all this can be found on github: https://github.com/markfasheh/btrfs-progs-patches/tree/qgroup-verify Please apply, Signed-off-by: Mark Fasheh <mfasheh@suse.de> Signed-off-by: David Sterba <dsterba@suse.cz>
* btrfs-progs: add quota group verify codeMark Fasheh2014-08-22
This patch adds functionality (in qgroup-verify.c) to compute bytecounts in subvolume quota groups. The original groups are read in and stored in memory so that after we compute our own bytecounts, we can compare them with those on disk. A print function is provided to do this comparison and show the results on the console. A 'qgroup check' pass is added to btrfsck. If any subvolume quota groups differ from what we compute, the differences for them are printed. We also provide an option '--qgroup-report' which will run only the quota check code and print a report on all quota groups. Other than making it possible to verify that our qgroup changes work correctly, this mode can also be used in xfstests for automated checking after qgroup tests. This patch does not address the following: - compressed counts are identical to non compressed, because kernel doesn't make the distinction yet. Adding the code to verify compressed counts shouldn't be hard at all though once kernel can do this. - It is only concerned with subvolume quota groups (like most of btrfs-progs).
