Dharmesh,
This may sound a bit repetitive from what support has told you,
but here's what I'd try:
First, this appears to be a NFS problem. Even so, what I would do is
first isolate it completely from VCS. To do this, I would stop VCS
(hastop -all) and make sure that all the resources were offline. Then I
would bring up the IP, import the disks, mount the mounts, ect... by
hand. Then I would try to access it from the client. (If you really
want to, you could try and export something that wasn't under VxVM
control too). If you can do it manually, then you know that there isn't
a issue say with network connectivity, /etc/hosts or the like. If you
are still getting the same error, then...
I'd check your /etc/exports file. Make double sure that the volume is
exported. Also ensure that your client is attempting to mount the
volume with the same permissions as listed. (In other words that you
client is not trying to mount a ro FS rw)
If you've made any changes to /etc/exports, type exportfs -ra.
Verify /proc/fs/nfs/exports (and /var/lib/nfs/xtab) are correct.
Check that comms are good between the server and client, and that
everyone knows who the other is. Ping the client from the server and
the server from the client. Make sure that the names used are the same
as when you do the mount, and that there is not /etc/hosts entry messing
things up.

Subject: [Veritas-ha] Unable to mount volumes on nfs-client in VSF 4.1
MP2for RHEL 4 AS U3 hosts.....
Hi,
We have 2 node VCS cluster. The specifics are as
follows:
Product Version : VERITAS Storage Foundation v4.1 MP2
for Linux
# of nodes in VCS : 2
HOST OS : RHEL AS 4 U3 (32 bit --
kernel-->2.6.9-34smp)
We've defined one fail-over service grp with bunch of
volumes to be shared via NFS. The service group
fails-over back-and-forth between 2 VCS nodes just
fine.
Howsoever, when we try to mount the exported volumes
on an NFS-client, we keep getting following error:
"reason given by server: Permission denied."
The NFS-client is also running RHEL AS 5 U3.
We also tried changing the permissions of mount-points
on the VCS hosts (/mnt/vcsvol*) to be 777.
1) SELinux is OFF on both the VCS hosts and the
NFS-client
2) FIREWALL is OFF on both the VCS hosts and the
NFS-client
We've opened a case with Symatec tech-support as
well..So far, we both (ourself and Symatec
tech-support) have tried following things without any
luck:
1) tried AIX client with the same results...
2) Upgraded the NFS package on all VCS hosts and
nfs-client to the latest level (as per RED HAT Errata)
3) Checked to see host.deny/hosts.allow on both the
VCS nodes and nfs-client....They all are empty.
3) Included foll. line in /etc/fstab on both the
VCS-nodes and nfs-client as well:
nfsd /proc/fs/nfsd nfsd defaults 0 0
4) Tried to export the shares to a specific nfs-client
(via main.cf) and also tried changing the "Client"
value to "*" in the SHARES part of main.cf...without
any luck.
5) We also tried providing "no_root_squash" in the
SHARE part of main.cf for one volume to see if that
helps. But no luck.
6) We also checked the foll. technote:
http://seer.entsupport.symantec.com/docs/277033.htm
We see that NFS is not supported for SLES..but for RH
it seems supported.
7) The major and minor numbers for the shared diskgrp
have already been checked.
The main.cf file has been ratified by Symantec
tech-support...but am pasting here for reference..
Will really appreciate any tips/tricks/pointers to
resolve this issue.
Thanks & Regards,
Dharmesh.
