Subject: [PATCH V2][BTRFS-PROGS] Improve output of mkfs.btrfs command
Date: Wed, 17 Dec 2014 21:14:04 +0100 [thread overview]
Message-ID: <1418847252-14184-1-git-send-email-kreijack@inwind.it> (raw)
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]"

-- 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
