Correction: that (verification) would be scrubbing ;)
I don't think that zfs would call it scrubbing unless the user
requested scrubbing. Unplugging a USB drive which is part of a mirror
for a short while results in considerable activity when it is plugged
back in. It is as if zfs does not trust the device which was
temporarily unplugged and does a full validation of it.
