Just curious about the mechanics of the zfs scrub process as I'm seeing reading and writing with the first scrub in progress since i added my 2nd vdev to pool.
I have re-copied alot of data to the pool since so all the data isnt just on the original vdev.
So at the start the graphs just showed reads (100-150MB/s) to the original vdev and nothing happening on the new vdev (first hour or so) but since then there has been writing (only around 100kB/s) to the new vdev and continued reading on original.
All the previous scrubs have been completed with single vdev and showed reading for the whole 5-6 hrs...
