Can not mount/umount cdrom

[Tingli]

I have upgraded hp-ux os from 11.23 to 11.31 in a rp3440 with Dec. 2007 bundle patch.

When the system comes back with the new OS, I can not mount the CD back again, by complaining the device is busy. I tried by cleaned up dfstab and sharetab and run shareall, still it is busy.

Then I created another new directory and mounted the CD there. Now I can not umount this CD too by complaining that it is busy. Again, I cleaned up files dfstab and sharetab. I run lsof and fuser on /dvdrom and there is nothing on it. But I still can not umount it.

Hi,
Try #fuser -ku /dvdrom

Hi,

did you export the mount point to NFS?
Doing so you usually don't get any output of the fuser command for this, though the nfsserver has a handle on it.

I did do nfs for the dvdrom and I need to run

# unshare /dvdrom

to release it.
