NFS Linux-HA Heartbeat : HOWTO UDP?
In the article HaNFS: Linux HA,
# If your kernel defaults to using TCP for NFS (as is the case in 2.6 kernels), switch to UDP instead by using the 'udp' mount option. If you don't do this, you won't be able to quickly switch from server "A" to "B" and back to "A" because "A" will hold the TCP connection in TIME_WAIT state for 15-20 minutes and refuse to reconnect.
The shared mounted volume is in /etc/ha.d/haresources.
Where do i set the NFS to default to UDP only. I looked up /etc/services and found nfs under both UDP/TCP.
Any hints .. or ideas?
