Hi there guys!
Just yesterday I finally finished the migration from 2 raid5 arrays to 2 raidz1 arrays...
After copying data back I thought it would be a good idea to scrub my pools.
A few minutes ago I started a scrub in the big array which holds about 4TB of data.
The information tab reports a scrub speed of about 300Mb/s.
Is this speed OK? What speeds do you get?

it will taken offline by the end of march 2021!
I like to aks Users and Admins to rewrite/take over important post from here into the new fresh main forum!
Its not possible for us to export from here and import it to the main forum!

Re: scrub speed
It really depends on the drives you have, RAM and processor speed. I think mine gets around 500Mb/s - or 63 MB/s.
As an aside, I reconfigured my pool recently from one big pool to several datasets. The amount of data did not decrease, but the necessary time to scrub the pool went down by about 33%.
