I configured a vnode-backed md and enabled swapping on it. A few
hours later after moderate swap use the console showed:
swap_pager: indefinite wait buffer: bufobj: 0, blkno: 889347, size: 8192
[...repeated...]
The backing store was a sparse file, but there was ample space:
# ls -l /data2/swapfile
-rw-r--r-- 1 root wheel 17179869184 Sep 11 16:50 /data2/swapfile
# df /data2
