* btrfs-progs: inspect: add command min-dev-sizeDavid Sterba2015-08-31
| | | | | | | | | | Previously in 'filesystem resize get_min_size', now 'inspect-internal min-dev-size'. We'd like to avoid cluttering the 'resize' syntax further. The test has been updated to exercise the new option. Signed-off-by: David Sterba <>
* Btrfs-progs: add feature to get mininum size for resizing a fs/deviceFilipe Manana2015-08-31
Currently there is not way for a user to know what is the minimum size a device of a btrfs filesystem can be resized to. Sometimes the value of total allocated space (sum of all allocated chunks/device extents), which can be parsed from 'btrfs filesystem show' and 'btrfs filesystem usage', works as the minimum size, but sometimes it does not, namely when device extents have to relocated to holes (unallocated space) within the new size of the device (the total allocated space sum). This change adds the ability to reliably compute such minimum value and extents 'btrfs filesystem resize' with the following syntax to get such value: btrfs filesystem resize [devid:]get_min_size Signed-off-by: Filipe Manana <> Signed-off-by: David Sterba <>
