--Sig_/H2/FUdg0bY=BMPNQjMrIaVY Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable I have a faulty pool with an ambiguous label and I tried to resolve that problem. ZFS is at the moment highly active copying data from several volumes to another. Operating system: 11.0-CURRENT FreeBSD 11.0-CURRENT #1 r259522: Tue Dec 17 19:02:10 CET 2013 amd64 In one terminal I exported the pool in question and tried to list it via "zpool import". But the this command sequence locks up the terminal for an hour up! In another terminal I tried to issue to command "zpool status" to watch the status of the pools (I have several). But this terminal ist alos locked up right now! What is wrong here? I had such an issue in 10.0-CURRENT as well. It seems ZFS is locking everything up and can only be brought back by a hard reset! What is going on? Why is zpool locking up in trying to display a label-scrambled pool while the zpool status is then also locked up, but latter is supposed to show the status of the other, healthy pools? This reminds me of single-threaded tools which looks up every operation consecutively issued after the blocking command. How is this to be solved?
