Hi All, enclosed a patches set to improve the output of mkfs.btrfs command. Currently I find the output of mkfs.btrfs command quite confusing: # mkfs.btrfs -f -M -d raid5 -m raid5 /dev/vd[b-k] Btrfs v3.17 See http://btrfs.wiki.kernel.org for more information. Turning ON incompat feature 'mixed-bg': mixed data and metadata block groups Turning ON incompat feature 'extref': increased hardlink limit per file to 65536 Turning ON incompat feature 'raid56': raid56 extended format Created a data/metadata chunk of size 8388608 adding device /dev/vdc id 2 adding device /dev/vdd id 3 adding device /dev/vde id 4 adding device /dev/vdf id 5 adding device /dev/vdg id 6 adding device /dev/vdh id 7 adding device /dev/vdi id 8 adding device /dev/vdj id 9 adding device /dev/vdk id 10 fs created label (null) on /dev/vdb nodesize 4096 leafsize 4096 sectorsize 4096 size 356.01GiB After my patches the output becomes: # mkfs.btrfs -f -d raid5 -m raid5 /dev/vd[b-k] BTRFS filesystem summary: Label: btrfs-test UUID: 1073cb19-b675-423d-9aba-caad7f1508a8 Node size: 16384 Leaf size: 16384 Sector size: 4096 Initial chunks: Data: 9.01GiB Metadata: 3.61GiB System: 18.06MiB Metadata profile: RAID5 Data profile: RAID5 Mixed mode: NO SSD detected: NO Features: extref, raid56 Number of devices: 10 UUID ID SIZE PATH ------------------------------------ -- --------- ----------- 62121322-5666-4ecf-bc8e-c9b3d9f60db9 1 50.00GiB /dev/vdb 6158cb13-3ae8-42b6-8603-660f1e5c8a7a 2 50.00GiB /dev/vdc b49516db-ddf5-4f54-8831-a4babc79e901 3 50.00GiB /dev/vdd 00b03d81-7d29-4894-8050-9dd205f97c41 4 50.00GiB /dev/vde f119a2ec-5ef0-436c-805e-c1b0612b05ca 5 50.00GiB /dev/vdf adee4f58-e094-4bd4-8c56-941527524f8d 6 50.00GiB /dev/vdg a8299171-2024-4057-ba56-1f83bf6d7e2e 7 50.00GiB /dev/vdh b694e275-e454-4dbd-beb0-e33c388cffa2 8 2.00GiB /dev/vdi 7cbe04b5-36cd-4ea7-be82-206d5487914e 9 2.00GiB /dev/vdj 7c320654-675e-456b-ac23-cfb148b8ea57 10 2.00GiB /dev/vdk Total disks size: 356.01GiB Each information is in its own row. The disks are listed with more information (disk uuid, id, size of each disk...) Nodesize, Leafsize, Sectorsize are separated by the filesystem size. The metadata/data profile are displayed (before this information was missed). Also the size of the data/metadata/system chunk are displayed. This is an RFC to collect suggestions.
