- 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?

- To indicate the state of the machine here is some (possibly relevant) info.

- ---------------------------------------------------------------------------
- An " fsck -n /dev/user " says
- "File system not modified"
- I suppose this indicates that the file system is corrupted but that it
- cannot be repaired because of the -n flag.
- ----------------------------------------------------------------------------
-
- ----------------------------------------------------------------------------
- Any normal file related actions (creating, deleting, copying,
- searching files/directories ) get done without any problems whatsoever.

- The edited output of ps -el (only process names retained) on a typical
- occasion was :
- bdflush biod cpd cron getty inetd init lckclnt lockd logger lpsched mountd
- nfsclnt nfsd portmap ps rexd routed rwhod sched sed sh slink statd strerr
- vhand
- No user other than root was logged in. Root was logged in the root
- directory when this output was obtained.
