Hi All,

I have an urgent problem with some NFS mounts:

When I try to mount the NFS directories, I get a permission denied error.
If I do a df -k I get the following output:

abcd:root:/etc/rc2.d => df -k
Filesystem kbytes used avail capacity Mounted on
/dev/md/dsk/d0 8261393 7341688 837092 90% /
/proc 0 0 0 0% /proc
fd 0 0 0 0% /dev/fd
mnttab 0 0 0 0% /etc/mnttab

/dev/md/dsk/d4 216325417 192114915 22047248 90% /db2/dms
NFS fsstat failed for server wxyz: error 7 (RPC: Authentication error)
df: cannot statvfs /opt/SUNWspro: Permission denied
abcd:root:/etc/rc2.d =>

The following appears in /var/adm/messages:

Jan 27 16:24:07 abcd last message repeated 109 times
Jan 27 16:24:38 abcd nfs: [ID 664466 kern.notice] NFS getattr failed for
server wxyz: error 7 (RPC: Authentication error)

I have checked/done the following:
1. Restarted the NFS daemons on server: wxyz
2. Restarted the NFS daemons on server: abcd
3. Changed the mount point permissions to '777'
4. If I run a showmount -e OR a dfshares on server wxyz the directories are
exported
5. If on server abcd, and I run: dfshares wxyz I also see the directories
available

I am now out of idea's and urgently need some help please! Unfortunately I
cannot reboot the servers at the moment.

I will summarise.

Regards,
Alan.
