chkdsk on SAN LUN is it recommended and what will be the impact on data .


I have query from customer they want to run defragmentation on SAN LUN .

What are options available .



Chkdsk is not defrag. I would not recommend defrag unless there is a very specific work load that needs to be optimized.

WAFL writes data to disk in a way that the host never sees and also does all the hard work making reads and writes faster with cache and even flash.

About the only reason I can think of to defrag on netapp is preparing to shrink a lun on a platform with no snap drive support or native filesystem shrink feature.
