How many disks are there inside of c3t2100001378AC0253d0? How are they configured? Hardware raid 5? A mirror of two hardware raid 5's? The point is: This device, as seen by ZFS, is not a pure storage device. It is a high level device representing some LUN or something, which is configured & controlled by hardware raid. If there's zero redundancy in that device, then scrub would probably find the checksum errors consistently and repeatably. If there's some redundancy in that device, then all bets are off. Sometimes scrub might read the "good half" of the data, and other times, the bad half. But then again, the error might not be in the physical disks themselves. The error might be somewhere in the raid controller(s) or the interconnect. Or even some weird unsupported driver or something. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
