Hi all,

I had a problem similar to one posted below by Alan but could not find a
full summary.
I managed to fix my problem so here's the initial problem and then the

NFS Server A shares a writable share to a specific client B however
client B cannot write to it. Both servers running Solaris 10 sparc

Observations and checks:
- /etc/dfs/dfstab on Server A is:
/usr/sbin/share -F nfs -o nosuid,rw=clientB
- all nfs services on Server A running otherwise run: svcadm -v enable
-r nfs/server
- autofs is running on Client B and is accessing share via
- ensure that files and dir's on Server A has the same UID/GID numeric
settings as on Client B
- ensure all permissions in the full dir path of the share on Server A
are at least 555 (read+execute)
- we are using DNS in /etc/resolv.conf and /etc/nsswitch.conf


Change the share to point the fully qualified domain name of Client B
and the access of Server A from Client B must also be the same:
- /etc/dfs/dfstab on Server A:
/usr/sbin/share -F nfs -o nosuid,
- unshare  /zones/clientA/FileSystems/usr/sap/trans
- shareall
- on Client B:
cd /net/
- touch a

This was not a problem until we install some Live Upgrade minimum
patches recently (refer to latest version of SUN's infodoc 72099)

Hi All,

By sharing the filesystems as 'public' I could get them mounted.
if I share specifically for machine 'abcd' (-o rw=abcd) I get the errors

Hi All,

I have an urgent problem with some NFS mounts:

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

abcd:root:/etc/rc2.d => df -k

The following appears in /var/adm/messages:

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
5. If on server abcd, and I run: dfshares wxyz I also see the

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.
