Environment: NetApp FAS and Linux Suse
Desc: Added 100gb to an exisitng 100gb lun, but at server end this new 100gb is still not taken over.
Lun size: 200GB
Used size 70GB
Normally Shrinking a lun requires data migration to a new resized LUN, but if we already know the new blocks are free, and we need to say reclain 90GB out of the new unused 100GB - Is it possible to do it directly on netApp?
What will netapp reclaim first - the empty blocks of the lun (seeing from netapp perspective as it only shows 70GB in use 130gb free)?
