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: -- cut -- cut -- # 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 -- cut -- cut -- After my patches the output becomes: -- cut -- cut -- # mkfs.btrfs -L btrfs-test -f -M -m raid5 -d raid5 /dev/vd[b-k]" BTRFS filesystem summary: Label: btrfs-test UUID: 4409e381-f066-4e7b-af74-b6525fefa08b 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 ------------------------------------ -- --------- ----------- 907a3722-5d3e-4ee8-9cf1-e0e31c5edea7 1 50.00GiB /dev/vdb 2517a387-e060-46d1-9be7-9535802333c7 2 50.00GiB /dev/vdc 763dbe5e-8b16-4330-8730-8b60e245056b 3 50.00GiB /dev/vdd 180abbc2-4426-4f9c-a711-7735e19536d4 4 50.00GiB /dev/vde 666799fd-0413-42ce-bac4-a96e3e855ea2 5 50.00GiB /dev/vdf a6af3e09-8469-4e57-9fa0-9d82e6c8faf1 6 50.00GiB /dev/vdg e2b8a73e-2e37-4eb8-a8cb-71721a96b358 7 50.00GiB /dev/vdh 3fa65e67-88f6-48cc-9292-9336220e19a8 8 2.00GiB /dev/vdi 5a238ef4-e143-4b84-b698-347a1ceb7aa7 9 2.00GiB /dev/vdj 9794c5b4-8a9e-40d0-9774-b672034ef22b 10 2.00GiB /dev/vdk Total devices size: 356.01GiB -- cut -- cut -- Each information is in its own row. The devices are listed with more information (disk uuid, id, size of each devices...) 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. These changes are also available via github https://github.com/kreijack/btrfs-progs branch mkfs-verbose Changelog: v1: first issue (as RFC) v2: replaced "disks" with "devices" (suggested by Duncan) replaced "Feature" with "Incompat features" (suggested by Satoru) updated the comment of the documentation patch (suggested by Duncan) removed a duplicate "-q" in the documentation patch (suggested by Duncan) split the patch #6 in #6 and #7 to simplify the reading and review BR G.Baroncelli -- gpg @keyserver.linux.it: Goffredo Baroncelli <kreijackATinwind.it> Key fingerprint BBF5 1610 0B64 DAC6 5F7D 17B2 0EDA 9B37 8B82 E0B5 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
