If the errors bubble up to ZFS, then they will be shown in the output of "zpool status" Otherwise, you can use "iostat -En," as Casper noted, to show the error counters per disk. For more detailed information, use "fmdump -eV" -- richard -- ZFS Performance and Training richard.ell...@richardelling.com +1-760-896-4422
