I am in GZ doint zfs send -i | zfs receive to send snapshot form one pool to another pool . And I remembered I can use 'pv' in pipe to see progress. And I hit Ctrl+C to stop 'zfs send' and now nothing happens and 'zfs send' does not exits..

I feel really stupid right now. Shouldn't Ctrl+C instantly send break signal or something to 'zfs send' (and receive, on the same system) and get me prompt back.. ?

Oh, now after many minutes it did just that.. but probably it didn't help I previously hit it with some rsync inside VM

I got impression it shoudl instantly stop 'zfs send ' when I abort it with Crtl+C.. it is not the case..

nikolam: Send/recv processing does have kernel-threads servicing them, and they may be waiting/blocked on IOs to complete.

I had this happen to me recently with `zpool destroy` on an experimental throwaway pool I'd created with files in /tmp/.

and probably whatever zfs send managed to allocate from the pool will be deallocated again, which should take some time?
