btrfs-progs: mkfs: print the summary
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>
