Hello. I'd like to understand deeper about SSD scrubbing. Tried to read up online. Understand the concept and stuff but couldn't find enough information about how exactly Netapp handles it.
We have a netapp with two aggregates that are fully flash. The one with more volume count, more IO load seems to be not complaining on the AIQUM. It shows up as green but the other aggregate with more free space, lesser volumes compared to the former and less IO overall seems to show up with a warning symbol that its performance level is over loaded.
This looked strange and the only difference I could see is that the later had its scrubbing schedule run more than 6 months ago, the former ran last month. Nothing else seem different. Any help advice on how to navigate and find the problem would be much appreciated. Thanks!
