Operating Systems AIX NIM NFS file system cannot unmount Post 302747297 by omonoiatis9 on Friday 21st of December 2012 03:43:11 AM

sorry i didn't mention that before. yes i tried to ssh to NIM from the client and did who and i get the correct output.
in the meantime i already performed a reboot on the client just to clear it from the NFS.
i guess it would be a good idea to re-configure the server as NIM client.
it is strange though as it worked before and i experience this problem just this week.
but i think this is what i am going to do.

UMOUNT.NFS(8)						      System Manager's Manual						     UMOUNT.NFS(8)

NAME
umount.nfs, umount.nfs4 - unmount a Network File System SYNOPSIS
umount.nfs dir [-fvnrlh ] DESCRIPTION
umount.nfs and umount.nfs4 are a part of nfs(5) utilities package, which provides NFS client functionality. umount.nfs4 and umount.nfs are meant to be used by the umount(8) command for unmounting NFS shares. This subcommand, however, can also be used as a standalone command with limited functionality. dir is the directory on which the file system is mounted. OPTIONS
-f Force unmount the file system in case of unreachable NFS system. -v Be verbose. -n Do not update /etc/mtab. By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip delet- ing an entry. -r In case unmounting fails, try to mount read-only. -l Lazy unmount. Detach the file system from the file system hierarchy now, and cleanup all references to the file system as soon as it is not busy anymore. -h Print help message. NOTE
For further information please refer nfs(5) and umount(8) manual pages. FILES
