nfs mount hungs (Veritas file system)

Adithyan — Fri, 04 Apr 2008 07:58:25 GMT

Hi Friends,

I have created a veritas volume in a DG (nfsdg) and exported it for "everyone" with a "no_root_sqash" option.

From the client server, I am able to see the exported file system. But while mounting the server simply hungs!!!!

Any inputs please.....

From the nfs server:

/nfs (ro,wdelay,root_squash)
/nfs (rw,wdelay,no_root_squash,fsid=0)

From the cilent server:
showmount -e vmnode1
Export list for vmnode1:
/nfs (everyone)

Server OS:

uname -a
Linux vmnode2 2.6.9-34.EL #1 Fri Feb 24 16:44:51 EST 2006 i686 i686 i386 GNU/Linux

Veritas ver:

VRTSvxvm-platform-4.1.00.10-GA_RHEL4
VRTSvxfs-common-4.1.00.10-GA_RHEL4

Please help.

Thank you!
Adithyan

How look are you leaving the mount to finish the NFS mount.

I have found that there can be a delay of up wars of 2 - 3 mins on some nfs mounts the first time that the mount is used.

Once the mount has finished the performance is ok

Dear Friend,

I waited for half an hour :-(

It did not come. Now my question is whether any particular daemon or service should be running for veritas to support the NFS?

Thank you
Adithyan.

Hello Adithyan,

Can *any* NFS clients mount the exported filesystem or do all clients hang when attempting to mount? Can you collect a network trace of the hanging mount attempt and post it here?

Regards,

Dave

On your NFS server shutdown security for a quick test run...use the setup command:

setup
firewall configuration
disable

This is usually the most culprit
