Hallo, linux-btrfs,
I can''t switch a running "btrfs filesystem balance ..." via
ctrl z
bg
into the background, with other jobs this way works.
The stopping command "ctrl z" doesn''t work.
(may be on other keyboards it''s "ctrl y")
What goes wrong?
Viele Gruesse!
Helmut

I''ve got a patch that forks the process, and runs the ioctl in the background, returning immediately. I should be able to get it to the list this weekend as part of the userspace side of the balance management patches.
