It has nothing to do with the mount timeout: Chuck is talking about the
retransmission timeout for TCP connections 'timeo' which should indeed
be set to a high value since TCP guarantees message delivery (unlike UDP
which requires a small timeo value). Setting it too low means that you
end up spamming your server with a load of unnecessary retransmissions.
This was indeed the case for some older versions of 'mount' and also for
older versions of the am-utils/amd automounters.
Do you know how you tell what value of timeo is being used by default?
The source code for mount (nfsmount.c, part of util-linux v2.12) has the
comment:
/* timeo is filled in after we know whether it'll be TCP or UDP */
Can I assume, in this case, the value of timeo will be a suitable value
for tcp mounts?
Thanks
