I guess it still worked before you exported it. Your actual problem is 'zpool import' does not work for your pool. Maybe there is more broken than one disk. Why did you export/import to fix anything in stead of replacing the faulted disk? (I'm not into the code details of ZFS, so can't help you with everything.) Ronald.
