Hí there:

I'm having a problem that's driving me crazy. I have a Red Hat Enterprise Linux ES release 4.

And when I try to shut it down with:

#shutdown -h -y now

or init 0
I get the following error:

Umount: /usr: device is busy
(FAILED)
INIT: no more processes left in this runlevel

The only thing that I can do is to push the power button, but when I turn it on again I have the same problem

What can it be??

Thanks in advance!!

Epic

Are you doing "cd /" before you start the shutdown (or logging out and doing ctrl-alt-del)?

It may be your login that has it busied out.

In any event there are commands to show what is busying out a filesystem:

"fuser /usr" is th basic way to show what is using it.

"lsof /usr". This lists any process that is using it. This is the one I prefer.

I've seen occasions where fuser wouldn't show anything but lsof would find it. One example of that is a situation where you logged in as a user, did a cd /usr/something then did su to become root did a cd to another directory (like root's home) as root. fuser misses it because your effective name (root) is not busying out /usr but your real user (the one you originally logged in as) still has a shell on the filesystem. lsof will always find that shell.

welcome to LQ!!!


there's a lot of info about this issue on the web:

http://www.google.com/search?&q=umou...is+busy+failed

it seems to me like it's harmless...

i believe this is totally normal...

hmmm, this sounds like the common APM/ACPI issue... do you have your APM module loaded?? or an ACPI-enabled kernel??

First I want to thank you for your time

jlightner:

I tried your commands and I get this:

I think that this is a library problem, isn't??

Not a "problem". This is just showing you what files are open. Since most libraries are under /usr/lib this output isn't unusual.

I guess I should have specified trying the lsof at the point it tells you that it can't unmount /usr because its busy - looks like you did while system was normally running.

Also most binaries will have multiple libraries open so that is why you see (for example) "cmahostd" with its PID, 2403, 4 times in the list. Even though its there 4 times the name/PID combo lets you know it is one process. Later in the output you see "bash" multiple times then see PID, 3961, and PID, 3964. That lets you know those are two separate processes.

Most of what you see should shutdown during a normal shutdown as the init scripts will stop it (sendmail being one example). However bash since it is a user shell means someone is likely logged in or has a background process running. You can see the process itself by doing: ps -ef |grep PID (where PID would be the number in the second column - the process ID). Check to see what else is running in relation to those processes. Don't forget though that one of them is likely to be your own login session.

try rm -f /etc/ld.so.cache before you ran shutdown

did you upgrade your glibc package?

That's a new one on me. It doesn't seem reasonable removing something in /etc would have anything to do with unbusying /usr.

However, doing a google for the terms "ld.so.cache", "busy" & "/usr" came up with the following link:

http://www.ussg.iu.edu/hypermail/lin...03.0/0252.html

The post mentions something shy of removing the file (and unless it is something that gets recreated dynamically I would NOT remove it without doing more research).

Prior to doing all that I'd still do the lsof - that way you be sure of what is busying out /usr rather than just suspect it. There were other items that came up in above search but I didn't read them.

INIT: no more processes left in this runlevel ?

try this go to single user mode install initscripts...rpm and try.

/usr: device is busy ?

try this.. fuser -kv /usr

Thanks gadekishore
With those rmps the problem was solved!!

And thank u all for your help
