These two patches complement the previous two kernel-side
patches. The first implements a way of displaying the current progress
of any running balance process. The second patch allows a running
balance to be cancelled.
I'm a bit uncertain about the best name for these commands. Several
options:
1)
# btrfs filesystem progress <path>
# btrfs filesystem cancel <path>
Way too vague (cancel *what*?)
2)
# btrfs filesystem balance-progress <path>
# btrfs filesystem balance-cancel <path>
Clashes horribly with "filesystem balance" -- no abbreviations
possible.
3)
btrfs filesystem balance -p <path>
btrfs filesystem balance -c <path>
Changes behaviour significantly on a switch, in contrast to the
behaviour of the rest of the btrfs tool.
4)
btrfs balance progress <path>
btrfs balance cancel <path>
My current favourite, although we introduce a new namespace
("balance") for commands. We could add "btrfs balance start <path>" as
a synonym for "btrfs filesystem balance <path>", for some degree of
consistency.
At some point, I'll add a "monitor" function, which will poll at 1s
intervals for progress updates, and print out progress when it changes.
