* btrfs-progs: move global reserve to overall summaryDavid Sterba2014-12-04
| | | | | | | | | | | | | | | | | It looks confusing among the chunks, it is not in fact a chunk type. Sample: Overall: Device size: 35.00GiB Device allocated: 8.07GiB Device unallocated: 26.93GiB Used: 1.12MiB Free (Estimated): 17.57GiB (Max: 30.98GiB, min: 17.52GiB) Data to device ratio: 50 % Global reserve: 16.00MiB (used: 0.00B) ...

* btrfs-progs: cleanup filesystem/device usage codeDavid Sterba2014-12-04
| | | | | | | | | | | | | | | The main point of this is to load the device and chunk infos at one place and pass down to the printers. The EPERM is handled separately, in case kernel does not give us all the information about chunks or devices, but we want to warn and print at least something. For non-root users, 'filesystem usage' prints only the overall stats and warns about RAID5/6. The sole cleanup changes affect mostly the modified code and the related functions, should be reasonably small. Signed-off-by: David Sterba <dsterba@suse.cz>
* btrfs-progs: add section of overall filesystem usageDavid Sterba2014-12-04
| | | | | | | | | | | | | | | | | The 'fi usage' lacks an overall report, this used to be in the enhanced df command. Add it back. Sample: Overall: Device size: 35.00GiB Device allocated: 8.07GiB Device unallocated: 26.93GiB Used: 1.12MiB Free (Estimated): 17.57GiB (Max: 30.98GiB, min: 17.52GiB) Data to device ratio: 50 % ...

* btrfs-progs: compare unallocated space against the correct valueDavid Sterba2014-12-04
| | | | | | | | The device may not be fully occupied by the filesystem, the value of Unallocated should not be calculated against the device size but the size provided by DEV_INFO. Signed-off-by: David Sterba <dsterba@suse.cz>
* btrfs-progs: Print more info about device sizesDavid Sterba2014-12-04
| | | | | | | | | | | | | | | | | | | | The entire device size may not be available to the filesystem, eg. if it's modified via resize. Print this information if it can be obtained from the DEV_INFO ioctl. Print the device ID on the same line as the device name and move size to the next line. Sample: /dev/sda7, ID: 3 Device size: 10.00GiB FS occupied: 5.00GiB Data,RAID10: 512.00MiB Metadata,RAID10: 512.00MiB System,RAID10: 4.00MiB Unallocated: 9.00GiB Signed-off-by: David Sterba <dsterba@suse.cz>

* btrfs-progs: Add helpers functions to handle the printing of data in tabular ↵Goffredo Baroncelli2014-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | format This patch adds some functions to manage the printing of the data in tabular format. The function struct string_table *table_create(int columns, int rows) creates an (empty) table. The functions char *table_printf(struct string_table *tab, int column, int row, char *fmt, ...) char *table_vprintf(struct string_table *tab, int column, int row, char *fmt, va_list ap) populate the table with text. To align the text to the left, the text shall be prefixed with '<', otherwise the text shall be prefixed by a '>'. If the first character is a '=', the the text is replace by a sequence of '=' to fill the column width. The function void table_free(struct string_table *) frees all the data associated to the table. The function void table_dump(struct string_table *tab) prints the table on stdout. Signed-off-by: Goffredo Baroncelli <kreijack@inwind.it> Signed-off-by: David Sterba <dsterba@suse.cz>

| | | | | | | | | | | Before this patch, when btrfsck found an error in root dir, it will only output the following message "root %llu root dir %llu error" without any detailed error.

* btrfs-progs: apply realpath for btrfs fi show when mount point is givenGui Hecheng2014-11-27
| | | | | | | | | | | | | | | | For now, # btrfs fi show /mnt/btrfs gives info correctly, while # btrfs fi show /mnt/btrfs/ gives nothing.

| | | | | | | | | | | | | | | | If you exec: # btrfs sub show <dir> <== non-subvolume dir The cmd print error messages as expected, but returns 0. By convetion, it should return non-zero and we should explicitly set it before it goto out. With other pieces adopted: 1) removed a unnecessary return value set -EINVAL 2) fixed another code branch which may return 0 upon error. 3) with 2) applied, the ret = 0 follows can be removed Signed-off-by: Gui Hecheng <guihc.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz>

* Btrfs-progs: fix a bug of converting sparse ext2/3/4Liu Bo2014-11-25
| | | | | | | | | | | | When converting a sparse ext* filesystem, btrfs-convert adds checksum extents for empty extents, whose disk_bytenr = 0, and this can end up with some weird problems, one of them is the failure of reading free space cache inode on mounting converted btrfs. The fix is simple, just to skip making checksum on empty extents. Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Signed-off-by: David Sterba <dsterba@suse.cz>
