thank for reply

can i set the path also in nfs format ?

for example i have as second datastore in a nas

in format /nfs/datastorenas/snapshot ( where snapshot is the folder created as snapshot space destination)

can i set workingDir parameter with this path ?

how can i see if work correcly ?

thank again Alberto

1) do nas mount using esxcfg-nas

2) workingDir=/vmfs/volumes/<nfs location>

3) When you create snapshot, vmsd and vmsn should create in your specified location.

Try with one vm first!

Whatever you try do do, keep in mind that snapshot disks in VMware products are used as chains! Depending on the storage the performance may be degraded and I am not sure whether it is supported to have different parts of a virtual disk (base vmdk, snapshot vmdk) on different storage types.

Please take a look at the diagram under "The Disk Chain" in http://kb.vmware.com/kb/1015180

This explains how snapshots work. As you can see each of the snapshot files is in use by the VM and placing a snapshot file on another datastore type may (not necessarily) cause issue.
