Hi our topology is as follows:
We have a Netapp Storage Controller with two nodes
each node contains an IP address and hosts different datastores
(essentially each aggregate is hosted by a separated node)
the datastores are NFS (NFS version 3)
we've mounted our Datastores with a DNS name to all ESXI servers
we would like to move the datastore from one node to the other (using Vol move that will copy it to another aggregate)
(we've figured out the storage side of things so i won't elaborate of this)
this could be accomplished on the fly but would entail performance issues on the volume
because it would have to traverse between nodes on the Netapp Controller
to solve these performance issues we would need to change the DNS record on the DNS server to point the DNS name to the new node's ip address and then somehow
force the ESXI server to remount the NFS volume with the new ip address
from the output of " esxcli network ip connection list" i see that the ESXI server contains one TCP connection for each NFS datastore
is there a command that issues a remount? or does the ESXI server have some kind of mechinesemn that refreshes the DNS cache and performs a remount?
and also i would like to know what happens once a remount takes place? does the NFS protocol tolerate the downtime?
