The best thing to do here is again to boot noimport. Next, run the zpool import in the background. Once that appears to be hung, you'll want to run something like this: $ pgrep zpool $ # Note the output pid from pgrep and substitute with <pid> below $ mdb -ke '0t<pid>::pid2proc | ::walk thread | ::findstack -v' That should generate output and tell us where in the kernel the threads that appear to be hung are. Based on that, we should be able to make more progress. Just to make sure, you haven't done anything like remove the cache device have you?
