- version 3.17
- check: --init-csum-tree acutally does something useful, rebuilds the whole
csum tree
- /dev scanning for btrfs devices is gone
- /proc/partitions scanning is gone, blkid is used exclusively
- new subcommand subvolume sync
- filesystem df: new options to set unit format
- convert: allow to copy label from the origin, or specify a new one

Subject: [PATCH 13/42] btrfs-progs: Print more info about device sizes
|
|
|
|
The entire device size may not be available to the filesystem, eg. if
|
|
it's modified via resize. Print this information if it can be obtained
|
|
from the DEV_INFO ioctl.
|
|
|
|
Print the device ID on the same line as the device name and move size to
|
|
the next line.
|
|
|
|
Sample:
|
|
/dev/sda7, ID: 3
|
|
Device size: 10.00GiB
|
|
FS occupied: 5.00GiB
|
|
Data,RAID10: 512.00MiB
|
|
Metadata,RAID10: 512.00MiB
|
|
System,RAID10: 4.00MiB
|
|
Unallocated: 9.00GiB
