[Łukasz Wąsikowski]

Hi,

I cant remove log device from pool - operation ends ok, but log device
is still in the pool (bug?).

When I try to remove log device operation ends without errors:

# zpool remove tank mirror-1; echo $?
0

But the log device is still there:

# zpool status tank
  pool: tank
