There are different methods of scrubbing. Some memory controllers will do it for you, so we defer to them. If that is not the case, then you might see scrubs occurring as (software) kernel thread, memscrubber. For x86 AMD, you can see some of the logic here: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/i86pc/os/memscrub.c To get all of the details for each platform, you'll need to look at the various architecture-specific sources. Note that there are reasons why a scrub won't do much for you, particularly if you are not using ECC memory. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
