* Btrfs-progs: add -b to btrfsck to look at backup rootsJosef Bacik2013-11-07
| | | | | | | | | | In some cases the tree root is so hosed we can't get anything useful out of it. So add the -b option to btrfsck to make us look for the most recent backup tree root to use for repair. Then we can hopefully get ourselves into a working state.

* btrfs-progs: add filter for deleted but uncleanded subvolumesDavid Sterba2013-10-24
| | | | | | | | | | | | | New option to subvolume list that acts as a global filter and applies the other filters to either live subvolumes or the uncleaned ones. The path to the deleted subvolumes is lost at the deletion time, sample output looks like: ID 259 gen 7 top level 0 path <FS_TREE>/DELETED Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>

* Btrfs-progs: make pretty_sizes take u64 instead of a doubleJosef Bacik2013-10-24
| | | | | | | | | | | | | This got changed to a double but all the callers still use a u64, which causes us to segfault sometimes because of some weird C voodoo that I had to have explained to me. Apparently because we're using a double the compiler will use the floating point registers to hold our argument which ends up not being aligned properly if you don't actually give it a double so it will cause problems for other things, in our case it was screwing up str_bytes so it was larger than the actual size of the str. This patch fixes the segfault. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
* btrfs-progs: filesystem show of specified mounted disk should workAnand Jain2013-10-24
| | | | | | | | | | Originally, thinking was user will use mount point if the disk is mounted. But thats not really true, actually user don't (or shouldn't) care to check if disk mounted, so whether disk is mounted/unmounted when disk path is specified it should work.

* Btrfs-progs: make sure we return an error when we can't add a deviceJosef Bacik2013-10-24
| | | | | | | | | | I noticed xfstests was failing in a weird way but it was because our device add was failing but not actually returning an error so we were failing further down the test.

* mkfs: fix mkfs -r to properly allocate spaceChris Mason2013-10-16
| | | | | | | | | | | | | | | | mkfs -r wasn't creating chunks properly, making it very difficult to allocate space for anything except tiny filesystems. This changes it around to use more of the generic infrastructure, and to do actual logical->physical block number translation. It also allocates space to the files in smaller extents (max 1MB), which keeps the allocator from trying to allocate an extent bigger than a single chunk. It doesn't quite support multi-device mkfs -r yet, but is much closer. Signed-off-by: Chris Mason <chris.mason@fusionio.com>

* btrfs-progs: device scan use BTRFS_SCAN_LBLKID by defaultAnand Jain2013-10-16
| | | | | | | | | | | | | | | | | with this patch, BTRFS_SCAN_LBLKID (which leverages lblkid to look for btrfs disks) would be the default scan method to look for the btrfs disks. And thus the output as seen in the latest btrfs fi show and btrfs fi show -m for the mounted disks will have the consistent disks path. (it was inconsistent (across disks) because btrfs dev scan provided a different path from the mount command eg. below) devid 1 size 1.98GiB used 435.00MiB path /dev/mapper/mpatha devid 2 size 2.00GiB used 415.00MiB path /dev/dm-1 Signed-off-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
* btrfs-progs: use BTRFS_SCAN_LBLKID as default scan in filesystem showAnand Jain2013-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | btrfs progs has to scan for the btrfs disks for two main reasons, one to register them with the btrfs kernel (under btrfs dev scan) 2nd to report btrfs disks to the user (under btrfs fi show) (there few more minor reasons like check_mounted etc..). To facilitate the scan, in total we have the following methods to scan for the btrfs BTRFS_SCAN_PROC which uses the /proc/partitions to look for the disks, when scanning it does it twice first would look for non dm- paths and in the 2nd scan it would pick only dm- paths. BTRFS_SCAN_DEV which scans all the block dev under /dev as they appear during scanning. BTRFS_SCAN_LBLKID this uses the library functions provided by the lblkid to get only disks which contains the btrfs SB. The better method to use would be BTRFS_SCAN_LBLKID for the obvious reasons we don't have to reinvent that feature with in btrfs-progs. For the btrfs fi show - This patch will.. - make BTRFS_SCAN_LBLKID as the default scan option (BTRFS_SCAN_DEV is accessible under the option --all-devices and BTRFS_SCAN_PROC won't be used by btrfs fi show any more) Signed-off-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
* btrfs-progs: use kernel for mounted disk for showAnand Jain2013-10-16
| | | | | | | | | | | | | As of now btrfs filesystem show reads directly from disks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I hit a segfault when deleting a subvolume with very long name(>4096), it's because cmd_subvol_delete() calls strdup() and passes NULL as argument, which is returned by realpath(3).

In order to improve the scalability of show_qgroups(), i add some important structures: struct qgroup_lookup { struct rb_root root; } /* *store qgroup's information */ struct btrfs_qgroup { struct rb_node rb_node; u64 qgroupid; u64 generation; u64 rfer; u64 rfer_cmpr; u64 excl_cmpr; u64 flags; u64 max_rfer; u64 max_excl; u64 rsv_rfer; u64 rsv_excl; struct list_head qgroups; struct list_head members; } /* *glue structure to represent the relations *between qgroups */ struct btrfs_qgroup_list { struct list_head next_qgroups; struct list_head next_member; struct btrfs_qgroup *qgroup; struct btrfs_qgroup *member; } The above 3 structures are used to manage all the information of qgroups. struct { char *name; char *column_name; int need_print; } btrfs_qgroup_columns[] We define a arrary to manage all the columns that can be outputed, and use a member variant(->need_print) to control the output of the relative column. Some columns are outputed by default. But we can change it according to the requirement of the users. For example: if outputing max referenced size of qgroup is needed,the function 'btrfs_qgroup_setup_column()' will be called, and the parameter 'BTRFS_QGROUP_MAX_RFER' (extend in the future) will be passsed to the function. After the function is done, when showing qgroups, max referenced size of qgroup will be output.

* btrfs-progs: device add should check existing FS before addingAnand Jain2013-10-16
| | | | | | | | | | | | | | | as of now, when 'btrfs device add' adds a device it doesn't check if the given device contains an existing FS. This patch will change that to check the same. which when true add will fail, and ask user to use -f option to overwrite. further, since now we have test_dev_for_mkfs() function to check if a disk can be used, so this patch will also use this function to test the given device before adding.
