Hi,
It's been a while since I've had to deal with nfs mount points and moving underlying storage so I can't remember if it will just reconnect automatically.

I'm going to be rsyncing data from san1:/some/mount(iscsi) to san2:/some/newmount(nfs) mounted on server1 as /san1/disk and /san2/disk respectively

There are a bunch of servers that have in /etc/fstab san1:/some/mount /san1/disk nfs rsize=8192,wsize=8192,actimeo=30,retry=30,hard,bg, intr 0 0

My question is, assuming I don't care about potential failed writes, when I change DNS (going from linux box sharing iscsi disk over nfs, to san sharing volume straight nfs), will the clients just reconnect after some timeouts... or will all machines need to be rebooted?
