On the console I was seeing retryable read errors that eventually failed. The block number and drive path were included but not any info I could relate to the actual disk. zpool status showed a nonzero count of READ errors but nothing more. > Otherwise, you can use "iostat -En," as Casper noted, to show the error > counters per disk. For more detailed information, use "fmdump -eV" What I needed was to identify the drive and Casper and Jim's suggestion to look at /var/adm/messages was where I found the info. It is just a drive going bad AFAIK and ZFS is working fine including letting me detach the bad drive from a mirror and not screwing up my data. Thanks again to everyone. _______________________________________________ zfs-discuss mailing list email@example.com http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
