Even if it might not be the best technical solution, I think what a lot of people are looking for when this comes up is a knob they can use to say "I only want X IOPS per vdev" (in addition to low prioritization) to be used while scrubbing. Doing so probably helps them feel more at ease that they have some excess capacity on cpu and vdev if production traffic should come along.
That's probably a false sense of moderating resource usage when the current "full speed, but lowest prioritization" is just as good and would finish quicker.. but, it gives them peace of mind? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
