Hi all,
I have a question born mostly out of curiosity but also slight paranoia. I don't know VMware very well so forgive me if I'm missing something obvious.
I have a VMware lun that is thin-provisioned and presented via FC. vSphere reports that the lun has no VMs in it, and yesterday I deleted the datastore from VMware. It was only mapped to one cluster. The lun is currently offline and no-one's complained (yet).
On the filer, it reports that the lun occupies 962.9gb of its 1tb. Surely it should be empty?
There are no snapshots. We don't use snapmirror. Fractional reserve was set to 100 but I've since set it to 0 and it made no difference. I haven't been here long so I don't know any more history I'm afraid.
Any ideas?
Thanks, Peta
P.S. If anyone was curious about my last email sent to this list re reallocation and de-duped volumes, I can't get a detailed answer from NetApp support aside from "generally, don't reallocate de-duped volumes". So that's what I'm doing (or not, so to speak).
