I am guessing you are running a
command to perform these backups and it is the client that is not able to unmount.
To debug - you could start with using rpcinfo -p <NIM> | grep nfs to see if the nfs demons are recognized.
The other question I would have is whethr this client has more than one IP address and/or nim route back to the nim server. If it is, the way I debugged the interface being used by default is the telnet/ssh to the nim server (use the <NIM> name as hostname, and then after login, use the command "who" to show which IP address/hostname is recognized as originating IP address.
Compare these values to what a "working" client returns.
My gut feeling, if I read corrently it is the same client that fails, is that there is a configuration difference between this client and the one that succeed.
Hi,
I try to unmount :
smbumount /mnt/directory
But I receive :
Could not umount /mnt/directory: Device or resource busy
Any idea ?
Many thanks. (4 Replies)

Hi, suppose I have file system path say /foo/bar/baz then how would I find out whether it is local file system or NFS? If it is NFS then I want to find out the host where file system is located.

Hello Guru's
We are trying to save some data for 10 -15 yrs. so we created a NFS share file system and mounted on AIX 5.3 servers, keeping in mind that we might need to replace the expired disk/bad disk every 2 yrs or 4 yrs.
Now we are trying to solve. How to protect it from getting deleted... (6 Replies)
Right, now that I've finally worked out this website, I'll ask my question!
I am having an absolute nightmare with NFS on AIX. I have used it many times, and I know what I'm doing, however I cannot fathom what is going on here. I have 2 LPARs, sitting on the same physical host. They are... (12 Replies)

mountd
mountd(8) System Manager's Manual mountd(8)NAME
mountd - Services remote NFS compatible mount requests
SYNOPSIS
mountd [-d] [-i] [-n] [-s] [exportsfile]
FLAGS
Verifies the Internet addresses of hosts that make mount and unmount requests. If a client's address cannot be translated into a host name
by the gethostbyaddr() function and then translated back into the same Internet address by the gethostbyname() function, the request is
rejected.
This option requires the BIND service for Internet address resolution. It offers the highest level of security, especially when
combined with the -i option. Turns on Internet address verification and domain checking. If you are running the BIND service,
mountd verifies that a host making a mount or unmount request is in the server's domain. Allows non-root mount requests to be
served. This should only be specified if there are clients such as PC's that require it. ULTRIX BSD is allowed non-root mount
requests by default. Use the -n flag to allow non-root mount requests. Verifies the Internet address of hosts that make mount and
unmount requests. If a client's address cannot be translated into a host name by the gethostbyaddr() function, the request is
rejected. If you are running the BIND service, the BIND server is used to translate the address. If you are not, the /etc/hosts
file is used.
If the -i option is not used and a client's address cannot be translated, the address is converted to a string of the form
xx.xx.xx.xx. This allows access to exported file systems that do not specify a list of allowed hostnames.
The -i option is automatically enabled when either the -d or the -s option is specified. Turns on Internet address verification and
subdomain checking. If you are running the BIND service, mountd verifies that a host making a mount or unmount request is in the
server's domain or subdomain.
DESCRIPTION
The mountd daemon is the server for NFS protocol mount requests from clients. The mountd daemon responds to requests from remote computer
systems to mount directories. When it receives a SIGHUP signal, mountd rereads the exports file. If you are on an NFS client and want to
have changes to the export options on existing NFS client mounts take effect immediately, issue the showmount -e command and specify the
name of the host that is exporting the directory or file system (where the exports file is located). This ensures that NFS is aware of the
export list and options.
The optional exportsfile argument specifies an alternate location for the exports file. /etc/exports is the default.
Note, NFS Version 2 can export partitions that are greater than 2 gigabytes. However, they appear as 2 gigabyte partitions when viewed
from NFS clients.
