RHEL AS4 NFS client can not mount volum during the boot time.

Symptom:

Got the following error in the /var/log/messages file during the boot. But after the boot manually mount is OK.

Jun 25 14:58:03 laappt6 mount: mount: mount to NFS server 'laappt3' failed:
Jun 25 14:58:03 laappt6 mount: System Error: No route to host.

Cause:

The NFS mount script runs during the network initialize phase.

Solution :


Found two solutions from web.

1. append "/bin/mount -a " in /etc/rc.d/rc.local

2. insert the following line in to /etc/rc.d/init.d/netfs file.


before :

[ ! -f /var/lock/subsys/portmap ] && service portmap start
action $"Mounting NFS filesystems: " mount -a -t nfs,nfs4

after :
[ ! -f /var/lock/subsys/portmap ] && service portmap start
#added by David W.
action $"Sleeping for 30 secs:" sleep 30
#end of added by David W.
action $"Mounting NFS filesystems: " mount -a -t nfs,nfs4
