How to configure reasonable timeout for nfs?
timeo and retrans are effective only on soft nfs not on hard nfs.
Need to change the /etc/fstab like this:
<remote-host-ip>:/path/to/origin /shared/point nfs soft,timeo=30 0 0
timeo is timeout value of 30 deciseconds (3 seconds). there is also the retrans means how much retries to do in case of error.
then in case of server or service down, an error occurred after 9 seconds.
