Swapping CD's

Denton Williams — Thu, 17 Jan 2002 19:34:24 GMT

Hi All,
I have been prompted to insert the second CD while I am doing an install. The problem is that when I try to eject it won't eject and when I try to unmount it gives a message the the device is busy. What other kinds of actions should I take.

CHeers,
Dee.

Hi
Two things to check:-
1. That you are not in or using the mount point.
2. Fuser -u point will show if anything else is.

This sounds like an Oracle 8.1.x install. The real key to this is to not start in the /cdrom directory but rather in another directory and execute the installer with an absolute pathname. Then when are prompted for the 2nd CD, you are able to unmount/mount.

Hi,

find the process using the CD drive
# fuser -ku /cdrom
# fuser -ku {device file for CDROM}

Also you may be already in /cdrom.
#pwd
Verify that you are nod in that mount-point

Hi Denton,

You are probably in the directory where the cd is mounted. if there is a install process running it may get killed if you want to forcibly unmount the CD. This is how you forcibly unmount a cd/filesystem,

fuser -cu /mount_point

this will list the user and the process id of the process using that mount point. to kill all the process using the mount point,

fuser -ck /mount_point

Again do a fuser and see if there are any more processes left. If not try to unmount the cd/filesystem,

umount /mount_point

Hope this helps.
