I am attempting a storage vmotion between NFS datastores and get the error "Insufficient disk space on datastore".
ESXi 5.1b
The VM has three disks and a snapshot:
55 G, thin
100 G, thin
50 G, thick eager zeroed
The destination datastore:
Capacity: 10.00 TB
Provisioned Space: 12.66 TB
Free Space: 4.50 TB
So, plenty of space, but it is over-provisioned.
Storage DRS is enabled and the Utilized Space Threshold is set to 80%. Same issue if I disable Storage DRS.
If I drag the VM over any Storage DRS Datastore, active or not, the mouse changes to a circle with a slash through it, indicating an invalid destination. Other datastores show as acceptable, including one that is over-provisioned. Same results if I move one disk at a time. Same results if I increase the destination datastore to 15TB so it is no longer over-provisioned.
I will try deleting the snapshot when the VM owner is done with it, but that isn't the message I'm getting.
Is this a bug that is patched by update 2?
Is there a setting I am missing?
