pfs_mount problem..

Denton Williams — Fri, 25 Jan 2002 21:39:52 GMT

Hi All,
I am running HP-UX 11 and I have issued the pfs_umount command while doing an installation, but I am unable to open the CDROM device. Does anyone know what I can do to open it and change the CD, apart from starting the installation all over?

Thanks Dee.

Try 'pfs_umount -c or '

I'm not sure if you tried this but taking a look at the man page for pfs_mount explains the "-c" option for pfs_umount.

I hope this helps.

Hi,

You need to check whether any process is still running by using the CD. Check whether the CD is properly unmounted. If you want to kill any process which using the file system (CD), use 'fuser' command. Remember not to kill your installation process.

Denton,

I was wondering...
Did the pfs_umount command succeed, or did it
report Device busy? If it reported Device busy,
make sure you are not in the CD-ROM filesystem
(pwd) and try the command pfs_umount again.

Check out to see if CD-ROM is being used by a process.

# fuser -c /mount_point
# fuser -u /mount_point

kill it by sending KILL signal to the process if found and try again.

Best regards,

Hi, I met this before when I was doing installation which need 2 CDs. I think No way to change CD while installation process is still runing which opens this CD. All you can do is stop the CD and copy the 2nd CD into HD, then re-issue the installation.

To confirm my saying, I can use
fusser -u /mount_point
to see if the installation process is there.

Hi,

If is not too late and you haven??t rebooted the system you can try killing the pfs daemons in thir order:
pfsd.rpc
pfsd
pfs_mountd.rpc
pfs_mountd
It worked for me.
Best regards.
