This strongly suggests that you need to look for issue in some common component. It may be hardware like memory, caches, CPU, system busses or storage controllers, as you disks are apparently on the same controller. It may also be some software that corrupts memory contents. To troubleshoot HW issues you may consider running memtest86 or Oracle VTS for example. Setting kmem_flags to e.g. 0xf would be helpful to catch software issue.. regards victor _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
