While it's true that no software in the world is perfect and therefore there must exist bugs in ZFS and therefore I was overstated in saying cksum errors are always caused by hardware... The example you gave serves the opposite purpose. If the root cause of your problem was elevated temperatures, that's a hardware problem. _______________________________________________ OpenIndiana-discuss mailing list [email protected] http://openindiana.org/mailman/listinfo/openindiana-discuss
