RAID SCRUBBING - Recommended Practice

Recommended Posts

Al_Borges

Been about 18 months  with my QNAP -   overall very happy

 

question to the "RAID" experts

 

what is the recommended frequency for "raid scrubbing"   ?         I have it set for daily  but only get the occasional mismatched block or two

 

is too frequent a schedule harmful ?

Raid scrubbing? What is that? Consistency check?

I would go with monthly, unless you are seeing lots of issues, then I would go weekly. I assume there is increased drive activity/wear with scrubbing.

Some guidance from when the announced it:
