| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch prints the summary of the filesystem after the creation. The main fileds printed are: - devices list with their uuid, devid, path and size - raid profile (dup,single,raid0...) - leafsize/nodesize/sectorsize - filesystem features (raid56, extref, mixed-bg) - chunk size and type If the '-v' switched is passed, the output is more verbose; if the '-q' switched is passed, only the errors are printed. Below an example: BTRFS filesystem summary: Label: btrfs-test UUID: 14ae8a88-98ac-4f22-8441-79f76ec622f7 Node size: 4096 Leaf size: 4096 Sector size: 4096 Initial chunks: Data+Metadata: 9.01GiB System: 18.06MiB Metadata profile: RAID5 Data profile: RAID5 Mixed mode: YES SSD detected: NO Incompat features: mixed-bg, extref, raid56 Number of devices: 10 UUID ID SIZE PATH ------------------------------------ -- --------- ----------- df1c7f50-1980-4da2-8bc9-7ee6ffb0b554 1 50.00GiB /dev/vdb 32c808a0-cd7b-4497-a2c0-1d77a9854af9 2 50.00GiB /dev/vdc 3159782e-d108-40bc-9e15-090ecac160b4 3 50.00GiB /dev/vdd db7eaf0c-beb8-4093-a9d0-b9c25c146305 4 50.00GiB /dev/vde c367ca04-1f71-49c0-a331-11fc0b87e9fc 5 50.00GiB /dev/vdf e9b73c86-4058-4b3a-90ac-18741a276e70 6 50.00GiB /dev/vdg c4298b7a-ad41-4690-bf10-bf748b319413 7 50.00GiB /dev/vdh 1cf048c8-af8a-4225-b09a-5d12e9b217fa 8 2.00GiB /dev/vdi 7e157869-768a-4725-bad5-82e6bd05fd17 9 2.00GiB /dev/vdj 2c9431ac-c7f0-45a5-8529-cef8cf6e4033 10 2.00GiB /dev/vdk Total devices size: 356.01GiB Signed-off-by: Goffredo Baroncelli <kreijack@inwind.it> Signed-off-by: David Sterba <dsterba@suse.cz>

* btrfs-progs: mkfs: check metadata redundancySam Tygier2015-06-02
| | | | | | | | | | | | | | | | Currently BTRFS allows you to make bad choices of data and metadata levels. For example -d raid1 -m raid0 means you can only use half your total disk space, but will lose everything if 1 disk fails. It should give a warning in these cases. When making a filesystem, check that metadata mode is at least as redundant as the data mode. For example give warning when: -d raid1 -m raid0 Signed-off-by: Sam Tygier <samtygier@yahoo.co.uk> [make the check more visible in mkfs output] Signed-off-by: David Sterba <dsterba@suse.cz>

* btrfs-progs: drop feature defines from C files, in favour of CFLAGS definesDimitri John Ledkov2015-01-27
| | | | | | | | | | | | | | | | | | | | | | glibc 2.10+ (5+ years old) enables all the desired features: _XOPEN_SOURCE 700, __XOPEN2K8, POSIX_C_SOURCE, DEFAULT_SOURCE; with a single _GNU_SOURCE define in the makefile alone. For portability to other libc implementations (e.g. dietlibc) _XOPEN_SOURCE=700 is also defined. This also resolves Debian bug report filed by Michael Tautschnig - "Inconsistent use of _XOPEN_SOURCE results in conflicting declarations". Whilst I was not able to reproduce the results, the reported fact is that _XOPEN_SOURCE set to 500 in one set of files (e.g. cmds-filesystem.c) generates/defines different struct stat from other files (cmds-replace.c). This patch thus cleans up all feature defines, and sets them at a consistent level.

* btrfs-progs: Add minimum device size checkQu Wenruo2014-08-22
| | | | | | | | | | | | | | | | | | | Btrfs has global block reservation, so even mkfs.btrfs can execute without problem, there is still a possibility that the filesystem can't be mounted. For example when mkfs.btrfs on a 8M file on x86_64 platform, kernel will refuse to mount due to ENOSPC, since system block group takes 4M and mixed block group takes 4M, and global block reservation will takes all the 4M from mixed block group, which makes btrfs unable to create uuid tree. This patch will add minimum device size check before actually mkfs. The minimum size calculation uses a simplified one: minimum_size_for_each_dev = 2 * (system block group + global block rsv) and global block rsv = leafsize << 10 Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz>
