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

umount.nfs

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

       /etc/fstab	 file system table

       /etc/mtab	 table of mounted file systems
