Hello! Same problem with my pool! Yes it is zpool import problem. I have two pools (rpool and additional data pool) before reboot I have to do zpool export on that additional pool and zpool import after successful boot otherwise boot takes very long time (hours). That behavior can be observer also on OpenSolaris snv_118 (with corresponding zpool version).
