I have a vsphere 5.0 environment with 12 NFS datastores, this morning I noticed that 6 of the datastores free space match exactlly down ot the last bite. Free space is moving up and down in sync. The other datastores are not affected.
Verified the free space from the ESXi console and it also shows the 6 datastores moving in sync.
ESXTOP does not show anything abnormal.
We have an EMC San with 2 Netapp controllers as the front end.
Has anyone ran into this issue before?
