Hi Everyone,

I have  a vcenter datacenter cluster which is connected to a NetApp datastore and for some reason I'm seeing that something is chewing up all the space on the datastore. Are there logs in vcenter that allow me to see what accessing the datastore or taking up all the space?


Cheers

There are not really logs, that will help you.

What are the sizes of your VMs and datastore LUN sizes?

Are you using VMFS-5? Have you reclaimed storage space?

I've removed all the snapshots and disabled them from running but it didn't give me all that much space. The datastore if NFS

Yes there is a massive difference. The actual vms should take up about 1.3 TB and the datastore size has been set to 2.9TB. Even after I moved some of the vms to a different datastore the size reclaimed doesn't equal to the size of the vm moved.

Yes I'm getting this info from vCenter.

Interesting enough on the NetApp it tells me the Volume for the datastore is 2.95TB, Data space used is 1.77TB and the free space is 171GB which I managed to reclaim after I ran deduplication.

Netapp ah you got be careful with it
1)IN Datastore browse the datastore and is there a .Snapshot folder in the Datastore
2)If the physical Storage is thin provisioned then you need to ssh to the storage and ls -ltrh to get the right details
