We're having some read latency issues on a particular volume in our environment. We can see both random- and sequential reads on the particular volume. Block size also seems to be bigger than on our other NFS datastores in our environment.
I have enabled read reallocation with the space-optimized option on the volume. Question: Do I also need to run a manually reallocation on the volume or will the volume start the reallocation in the background? Reallocate show doesn't show anything, only "This table is currently empty".

ONTAP will automatically move sequentially read data into a more optimized layout. You do not need to run a manual reallocate of the volume specifically for the read reallocation feature.
