- We have an 80486 machine running SCO-ODT (UNIX v.5.3.2). We have two
- hard discs, one containing the root partition while the other (designated
- as /dev/user) is mounted as /usr2. The problem is that we are unable to
- unmount the latter. umount complains "/dev/user busy" although the
- file system is not really busy. This behaviour is observed with
- unfailing regularity.
- As a result, we can never do a normal shutdown of the machine.
- Can anyone help?
-
- Wonderfull!
- We have this problem since we use SCO Unix (about 2 years), and we
- colud not solve the problem with our german distributors.
- We have several file systems, some are exported with NFS.
- And only one filesystem (/u) is *always* busy when we do a shutdown.
- The only difference is, that this filesystem is mounted from some
- DOS-PCs with Sun PC-NFS 3.0.1. The other filesystems are only mounted
- by unix-Workstations.

- Have you considered the possibility that the command umount is
- either on the busy filesystem or uses libs on the busy filesystem? I
- believe that this will make the filesystem appear busy. If this is
- your problem, you can either check for a stand-alone version somewhere
- (I know that Sun has /sbin for programs that can be used in
- single-user mode with nothing else mounted) or roll your own. Heck,
- you could even hardcode the parameters to umount(2) into the program
- and call it umountuser. Just remember to statically link it. :-)

- Best of luck!
