Title: RE: Shutdown Error (the old umount2 error)

Illegal seek sounds like a filesystem problem.

 

On the other hand, why aren't those processes you kill manually already down?  Also, fuser -mu /usr may provide useful info before you start killing processes.

 

HTH,

I'm having the same problem with a standard, unmodified RH 7.3. I verified that all the K and S links in runlevel 0 are present in response to an earlier suggestion from the list. And I don't have separate partitions in my /usr structure. Just a plain vanilla /usr structure.

However, the termination messages are the same, i.e.

Umount: /usr: Illegal seet
[Failed]
Init: No more processes....

Any ideas would be appreciated. This message is intended to keep the focus on this issue until some ideas start flowing.

Looking for suggestions on how to troubleshoot this thing more
easily:

Dual Athlon MP 2100+ workstation running RH Rawhide { a super
modified 7.3 } . IDE hard drive. The directories /usr and /usr/local
are on separate partitions for size reasons. The start for run level 0
is killall and reboot. With the help of a hapless passerby, I
compared level 6 Kxx symlinks to files in init.d and they are all
there with no redundant entries. Runlevel 0 has killall, halt.

The machine works great for numericals and simulations.  Problem
is when we shut it down. Almost acts like it's doing a cd to /usr 
before final shutdown. We get the familiar:

~~~~~~~~~~~~
Unmounting file systems:  umount2:   Device or resource busy
umount: /dev/hda3:  not mounted
umount: /usr: Illegal seek
    [FAILED]
INIT: no more processes left in this runlevel
~~~~~~~~~~~~

HOWEVER, it shuts down properly if I go into maintenance mode
and do:

~~~~~~~~~~
su                              { must be root }
/sbin/shutdown 0                { go to maintenance mode }
killall -9 minilogd             { one of the services affecting /usr }
killall -9 ntpd                 { another service affecting /usr }
killall -9 cupsd                        { last service affecting /usr }
umount /usr/local               { required to get rid of /usr }
umount /usr                     { unmount  /usr }
poweroff                        { or reboot -- works properly }
~~~~~~~~~~

For some reason I am missing something obvious. What have I
missed here?
