NFS will not mount on startup

[Joshua Goi]

Hi,

I have 2 remote directories which I wanted to mount automatically after bootup. I setup both in SAM and rebooted the system. One will mount while the other won't. I made sure that both have the same options when I set them up in SAM. Looking in fstab. I see both entries, with no difference between them in options. The other directory will only mount when I do a manual mount command. Does anyone has any idea what's going on here?

Thanks!

It probably fails to mount on startup. Do you see any messages about it in /etc/rc.log ?

Hi Joshua,

Did you checked the remote directory permissions?

Best Regards,

The order of services to start can be important as well. Example, you will not NFS mount anything until the system starts NFS daemons (nfsd and biod)

hi Joshua,

i am not sure but also you may check
/etc/rc.config.d/nfsconf file and look
AUTOFS=?

Hi,

Looks like its an issue specific to that mount as other nfs mount is working fine.

First check /etc/rc.log for any mount errors during system startup.

Another option to check the stuff will be by issuing mountall commnad after unmounting both nfs mounts. This should give error if there is any issue with fstab entry.

HI,

You may also look at the dmesg output and look for any possible errors related to NFS mount.

Also, you may want to try waht sudeesh has pointed out.

Are both the remote filesystems exported from the same server? If yes, you would have to look at the /etc/exports of nfs server for possible causes.

Joshua,

try to manually mount the nfs directory at the command line
That should give you some indication whether the remote directory is nfs mountable or not.
Check if the directories have been exported properly
Also do a
#showmount remotesystemname

thanks

Possible cause:

Incorrect networking in /etc/rc.config.d/netconf

It could be a misplaced character, or the networking is simply incorrect with regards to contacting the remote hosts.

If you can mount the directories after startup, then its probably not netconf. If you can't there are many possible causes.

Its not beyond the realm of possibilities that a router or firewall, or VLAN configuration is blocking NFS access.

You need to check network connectivity to those hosts prior to trying the NFS mount. This may necessitate you adding some code to the start jobs in /sbin/init.d or making your own little network checking program in the /sbin/init.d directory. A few commands such as ping can determine the situation.
