Thanks for your input! I will change my NFS mounts for hard instead of soft, as currently I have the following:

nfsserver:/data/01/one/datastores/100  /var/lib/one/datastores/100  nfs   soft,intr,rsize=8192,wsize=8192


any other options you might recommend or adapt?

If you care about your data, never ever use soft mounts. You risk corrupting all your vm images if something goes wrong with your nfs server and/or network connecting all of it.
