pfs_mountd

chad_c — Thu, 26 Mar 2009 18:42:49 GMT

Hello fellow HP Colleagues.

Hopefully someone can shed some light.

Have an HPUX 11.11 server.

Copied an ISO image to /tmp/oradisk/

then attempted to mount the ISO image to directory /cdrom

pfs_mountd &
pfsd &
pfs_mount /tmp/oradisk/DISK1.ISO /cdrom

now when attempting to cd to /cdrom my session locks up

attempted to pfs_umount /cdrom and my session locks up.

does anyone know how to umount the /cdrom directory without having to reboot the server?

rgds,
chad

Shalom,

pfs_mountd is an outdated format that is only needed for very specific application.

I would do one of the following things:

1) Take the iso file, burn a cd/dvd and try mounting that on the HP-UX server.

1) Mount the iso file on a linux system using the following command: mount -o loop filename.iso /folder
Copy the flies system to system using our protocol.

Hi Chad:

You must kill the processes in the _reverse_ order that you started them.

First kill 'pfsd' and then kill 'pfs_mountd'.

Of course, before you do the above, use 'pfs_umount' to unmount the mounted CD.

Now, if you have a system where the processor utilization is climbing, and/or 'bdf' is unresponsive, etc. you need to reboot to cure the problem.

Do _NOT_ use 'pfs_mount'. It leads to reboots; is deprecated; and is unnecessary!

There are patches for enable mounting RockRidge formats. Search the patch database for them is you need to apply them.

Regards!

thanks for the response

there are no pfs or pfsd processes running

the only process running is an attempt to unmount the cdrom ... which does NOT allow me to kill

txnnm1# ps -ef | grep pfsd
root 17469 26990 0 15:02:12 pts/1 0:00 grep pfsd
txnnm1# ps -ef | grep pfs
root 2806 1 0 14:08:46 ? 0:00 pfs_umount /cdrom
root 17562 26990 0 15:02:16 pts/1 0:00 grep pfs
txnnm1#

sounds like a reboot is the only option

Hi (again) Chad:

Make sure that you are not 'cd'd into the filesystem that you are trying to unmount.

You can use:

# fuser -f /cdrom

...to see what/if any processes are using it.

Hello.

No am not cd'd into the directory

when attempting to cd into the /cdrom directory, it locks up my session and does NOT allow me to pfs_umount /cdrom

This is all that is displayed.

txnnm1# fuser -f /cdrom
/cdrom:

am in the process of scheduling a reboot ... however wanted to check first if there is any other way to unmount the /cdrom

Once you reboot, make sure you have added the 3 RockRidge patches and never use pfs again. It became unstable at 11.00 and should never be used on 11.11 or higher. Ignore outdated non-HP documents from Oracle, Sybase, etc regarding pfs. The patches for 11.11 are:

PHCO_25841
PHKL_26269
PHKL_37535

Once installed, you will use the supported method: mount -orr to mount non-HP-UX CDs.

Thanks again for the responses.

When mounting a cd ... me myself always use mount.

the reason for me using pfs_mount is because am mounting an iso image

So my question is ... can an iso image be mounted using 'mount'?

if not, what is the best method to mount an iso image?

rgds,
chad

Hi (again) Chad:

If you apply the requistite patches and dispose of PFS mounts, you can do things like:

# mount -F cdfs -e -o ro,cdcase /dev/dsk/cXtYdZ /cdrom

# /usr/sbin/mount -F cdfs -e -o ro,rr /dev/dsk/cXtYdZ /cdrom

See the manpages for 'mount_cdfs(1M)'.

> pfs_mount is because am mounting an iso image

ISO image is unclear. The original CDROM standard was called ISO 9660 and is the basic CDROM format. Many manufacturers have used the term ISO image when they are referring to a binary image of a CD -- which could be in a number of different formats. The -orr option works for ISO 9660 as well as RockRidge Extensions. HP-UX cannot mount a PC-only Joliet image.

>what is the best method to mount an ISO image?

(Note it may be easier to just burn a CD as SEP said.)
I'm surprised nobody pointed you to the tens of threads about this.
