Operating Systems SCO NFS umount shows the "Device busy (Error 16)"
# 15

vbe:
right now I can not try 'fuser -k' because a 'fuser' show me pid of user processes, but if the solution is to get started to kill processes ...
The computer has only one lan connection.

Corona688:
I think the solution is to get started to kill all processes indicating fuser (complicated I find a schedule that is not with users)

I think it's a bug, I wrote the post if there is anything I see or am doing wrong .. (I need a different view to mine)
The SLED10 supports v2 and v3, and v2 SCO


jgt:
If it is true that the sco is old, but migrating is not so easy ... (we are about to migrate to 5.0.7 with VirtialBox)


When you find the time to kill the process, I comment.
Thanks for writing and for what will come Smilie

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
