Our NIM server has a filesystem named /export/mksysb just to hold mksysb images. We use to have the client LPARs NFS mount this filesystem and create their backups there, but with AIX 6.1 TL5, the NIM server doesn't like it when there is already a /export/mksysb entry in the /etc/exports that he didn't put there. Now, we have our NIM server tell the clients to create their mksysb's to the same /export/mksysb filesystem on our NIM server. The difference is that the backups are being handled by our NIM server and it maintains the entries in the /etc/exports file. These are the NIM commands that we use:
First remove the old mksysb resource and file to create enough space for a new mksysb:
Create a new mksysb file and NIM resource:
Also, the NIM server doesn't like to make 2 mksysbs going on at the same time because it may not complete correctly due to limited amount of space in the /exports/mksysb filesystem. This can be over riden by adding the "-F" option to the first part like this:

mountd
MOUNTD(8) BSD System Manager's Manual MOUNTD(8)NAME
mountd -- service remote NFS mount requests
SYNOPSIS
Obsolete. See nfsd(8).
DESCRIPTION
The mountd daemon was formerly the server for NFS mount requests from NFS clients. This functionality has been moved into the NFS server
daemon nfsd(8).
Please refer to nfsd(8) for NFS server documenation.
The following is a list of former mountd options that are now available as nfsd(8) options:
mountd option nfsd option Description
-n-N allow non-root mounts
-r-R allow regular file mounts
exportsfile -F exportsfile alternate exports file
However, such configuration options are normally specified via nfs.conf(5).
When the NFS server is started, it loads the export host addresses and options into the kernel using the nfssvc(2) system call. After chang-
ing the list of exports (either directly or indirectly via a change in netgroup membership), the administrator should send a hangup signal to
the nfsd daemon to get it to reload the export information:
kill -s HUP `cat /var/run/nfsd.pid`
For backwards compatibility, the following should also work:
kill -s HUP `cat /var/run/mountd.pid`
Any errors encountered while processing the export entries will be logged via syslog(3).
FILES
/etc/exports the list of exported filesystems
/var/run/mountd.pid the pid of the currently running mountd
/var/run/mountdtab the current list of outstanding mounts served
/var/run/mountdexptab
information about exported file systems and directories (UUIDs, handles, ...)
SEE ALSO nfsd(8), exports(5), nfs.conf(5), nfsstat(1), portmap(8), showmount(8)HISTORY
The mountd utility first appeared in 4.4BSD. It's functionality was merged into nfsd(8) in Darwin 9.
