mount error

MikeL_4 — Thu, 18 Mar 2004 13:38:38 GMT

I have pfs_mounted a PeopleSoft CD in a local hpux 11.0 and I want to install it on a remote hpux 11.0. I have the CD mounted on local server using pfs_mount, but when I try to mount on remote server I get:

mount servera:/cdrom /cdrom
Too many levels of remote in path

Turn off pfs_mount daemons and try the script i'm attaching. It might work.

pfs_mount is already using NFS which may be the trouble.

I think you need to do pfs_exportfs for the cdrom mount point and mount that on the remote host.

better yet as a long term solution do away with pfs_mounts altogether by patching your systems.

the following is "borrowed" from http://www.cmve.net/~merijn/

Do not use pfs_mount!. Install the Rock-Ridge extension patches instead and never worry about these problems. For HP-UX 11.00 you will need forget all about PFS and install PHKL_26448 (now superceded by PHKL_28060), PHCO_26449, and PHKL_26450 to have HP-UX recognize those file systems automatically on mount! For HP-UX 11.11 (11i) you need PHCO_25841, PHKL_26269, and PHKL_25760 (now superceded by PHKL_28025).

No need thereafter to use -o cdfs to mount anymore, provided you enter the CD drive in /etc/fstab like this:

/dev/cd0 /cdrom cdfs ro,rr,noauto 0 0

Long term solution will work, but not now.

I tried the mount command as suggested, and
received:
# /usr/sbin/mount -F cdfs -e -o ro,rr
/dev/dsk/c2t0d0 /cdrom
mount: illegal file system specific option rr
usage: mount [-l][-v|-p]
mount [-F FStype][-eQ] -a
mount [-F FStype][-eQrV][-o specific_options]
{ special | directory }
mount [-F FStype][-eQrV][-o specific_options]
special directory
#

so I did without the rr and it mounted, but
developers said it's not mounted correctly.
I gues in the pfs_mount it does a translate to unix and mount doesn't give that option that I can find..

/dev/dsk/c2t0d0 /cdrom pfs-rrip xlat=unix 0 0

once you get the CD pfs mounted on say /cdrom

add an entry /etc/pfs_exports or create if its not there.

/cdrom ro=host.fqn

# pfs_exportfs -a

Then you should be able to mount the cd on the other host.

Marvin Strong — Thu, 18 Mar 2004 14:31:12 GMT

actually the entry should be

/cdrom ro=remotehost.fqn

for example here I have:

/cdrom ro=hp19rm1.xxx.com

You must use pfs_mount on the remote system as well, not mount.

Here is a guid on how to do the whole process.

When I issue the mount on the remote server I still get error:

# mount uxas01:/cdrom /cdrom
Too many levels of remote in path
