It was then but the array (3511) reported several times 'Drive NOTIFY: Media Error Encountered - 163A981 (311)' and then I got all of these CKSUM errors. Once it stabilized (drive finally filed and was replaced by hotspare) I see no CKSUM errors after few days. Looks like drive was failing, etc. But still I'm surprised that the array returned bad data (raid-5 on the array). We see such messages once in a while on several 3511s. -- Best regards, Robert mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
