Description Geoff Reedy 1999-11-30 22:17:03 UTC
With initscripts-4.68 /usr will not unmount properly on halt/reboot.  At
the end of the shutdown sequence it says:

Turning off swap OK
Turning off accounting OK
Turning off quotas OK
Unmounting file systems umount2: Device of resource busy
umount: /usr: device is busy FAILED
INIT: no more processes left in the runlevel

and then hangs, the strange thing is that I don't have this problem on
another computer with very simillar configuration.

Does this only happen with 4.68 for you as opposed
to earlier/later errata releases?

Comment 2 Geoff Reedy 1999-12-01 17:56:59 UTC
I've had this problem ever since upgrading to 6.1

The problem is that fuser kills some stuff that shouldn't be killed.
I put in a fuser -v -m /usr to see what was getting killed.  It reported that
both rc and S01halt were using /usr.

After a little further investigation I figured out the whole of the problem:

These machines use LDAP for authentication, so ldap is in /etc/nsswitch.conf.
The libc loads the ldap library which is installed in /usr/lib.  As a result
every process depends on /usr.  So I guess this is really a bug with the
openldap rpm in that it should install libldap to /lib.

Comment 3 Bill Nottingham 2000-01-18 20:21:59 UTC
This is fixed in the nss_ldap RPMs in Raw Hide.
