SCO

vbe: No returns nothing
# fuser -u /cediback2
/cediback2:

from what I understand the man in nfs specify them as "host: filesystem."
also probe fuser 'fuser /tmp/fileEdited', but does not show me the pid of the process corresponding vi (I must have a conceptual error)


rbatte1: English is not my native language, I can not understand the semantics of "Another alternative would be That there is a sub-mounted filesystem," can you explain me what would be the case?


achenle: the same, "It could be shared Also back out" read the words but can not understand ..


hicksd8: yes, I would think the same .. but I'm not at the time of removal. Also he did not find the process that has "taken" the /cediback2.
SCO In the version I'm using no force umount option (or just do not see it)

I show the steps:

Code:

#  > pwd
/
#  > mount
/ on /dev/root read/write on Fri Aug 08 20:16:30 2014
/stand on /dev/boot read only on Fri Aug 08 20:16:30 2014
/cediback2 on pc10:/backup/cediback2 read/write on Sat Aug 09 07:23:10 2014
# > umount /cediback2
umount: /cediback2 busy: Device busy (error 16)

The directory is only backup, the execution would be as:
umount /cediback2 [sometimes works, sometimes not]
mount /cediback2
backup.sh
umount / cediback2 [sometimes works, sometimes not]

Being rather old-fashioned for a minute, I wonder if you need to:

Code:

 
 # sync
 # umount /cediback2

sync has been made largely obsolete but I wonder whether the O/S knows that it still has data to write and so won't let the filesystem go.
Just something I would try.

That might explain why sometimes it works and sometimes it doesn't.

sync; umount / cediback2
No improvement .. but gave me the idea of ​​running
'time find / cediback2 type f | xargs sync' (I'll try out production time)


I want to kill all processes in the nfs client .. (I have to see what they are and if I leave a copy inconsistent)

Is it a client, or a driver?

So you can also try a last

Code:

 fuser -k /cediback2

and see if it will umount next...
Do you have multi lan connection? like 2 network cards on your SCO box?

One node is SCO, what is the other? O/S? Are the two NFS version the same? Version 2,3 or 4? Perhaps the mount needs to be done with the version switch on the command line.

Also, have you considered that this could be a bug? (possibly with a patch issued to fix.)

Flako, you should upgrade to at least 5.0.6 with RS506a. It will install with your current license, as long as you do not have a Compaq branded license.
5.0.2 is as old as Windows 95, and was obsoleted by SCO in 1999.
