Extremely slow zpool scrub performance
Running a zpool scrub on our production pool is showing a scrub rate
of about 400K/s. (When this pool was first set up we saw rates in the
MB/s range during a scrub).
Both zpool iostat and an iostat -Xn show lots of idle disk times, no
above average service times, no abnormally high busy percentages.
Load on the box is .59.
8 x 3GHz, 32GB ram, 96 spindles arranged into raidz zdevs on OI 147.
