Thin Provision/Dedupe and how VMware see it


We are using a volume as our vmWare datastore, which is 5TB, both thin provisioned and deduped.  Currently it shows from System Manager as only using 40% of the space.

When I look at the vmware side, the volume is listed as 4TB with 29GB free.  Now, I have a vm that is sitting on another datastore and I need to move it to this one, but vsphere sees it as having insufficient disk space.



does the datastore really contains data for upto ~4 TB ?



It does not matter how much physical space is available. You still need logical free space the filesystem (datastore). You can create new datastore in the free physical space and move VM into it.
