Re: unmount error

Hi:

 

Try 'fuser -kc /testlv' to kill any processes using the mount point.  You could also use 'lsof' if you are interested in seeing what files are open.

 

Regards!

Re: unmount error

Make sure you haven't cd to that filesystem.

Make sure no one inside that directory.
If not know then you can do:
#fuser -ku <directory>

Hi
>umount: cannot unmount /dev/vg00/testlv : Device busy

Sometime fuser -ku is not giving any impact hence still indicate such error. if there has too many users access and execute something on that folder it would be causes this issue, the another choice is reboot the server

Re: unmount error

Hi:

 

Try to check y you have many sessions open o shell.

 

Maybe you  change to other shell prompt   like  # ksh  in side your  filesystem

 

check using  # ps -t  ttyxx   to check is you have other shell

 

Good lock
