NFS service not responding message on mount

[Mike Rightmire]

I am trying to mount a directory from a Linux (Debian) box to an HP-UX 11 box. I have exported the directory on the Linux box and CAN mount it on a different HP-UX 10.20 box. I also CAN mount a directory from another HP box on the HP-UX 11 system.

However, I CANNOT mount the Linux directory on an HP-UX 11 box. When I try I get the error ...

NFS service not responding(retry delay=5s)
nfs mount: retry: retrying(1) for : /[directory attempting to mount to]
nfs mount: retry: giving up on : /[directory attempting to mount to]

... and it stops attempting to mount. To summarize...

I CAN mount an exported HP-UX 10.20 directory on my HP-UX 11 box
I CAN mount an exported Linux directory on the HP-UX 10.20 box.
I CANNOT mount an exported Linux directory on the HP-UX 11 box.

Thanks in advance for all the great help!

Hi Mike !

Did you try to mount your linux exported filesystem onto your HPUX 11.X box with the help of the 'version' flag ?

Try this from your 11.X box:

mount -F nfs -o vers=2 linux-server:/exported-directory /mountpoint-on-your-hp-box

Change vers=2 to vers=3 and retry.
Alternatively, you can try mounting it read-only.

Is your export accessible from your 11 box (no -access on the exports file of your linux box) ?

I hope this helps.

Regards.

Fred.

Thanks forthe quick ideas. Unfortunately, I tried both suggestions and neither worked. Same error message. The confusing part is the error seems to be generated by the linux box, but I can mount other HP-UX boxes to the exported linux directory fine. THIS makes me think it is a setting on the HP-UX 11 box. Hmm...?

Also, as an aside, I CAN ping the Linux box from the HP-UX 11 box fine. The HP-UX 11 box IS setup as an NFS client, but disabled as an NFS server. I don't know if that matters.

Thanks again!

Mike,

I agree with Frederic that it might have something to do with the supported nfs versions on the HP-UX11 box. You can find out which versions it supports by issuing

rpcinfo -u mountd

on the 10.20 box. Also, try to find out with which options the filesystem is mounted on the 10.20 box:

nfsstat -m

Then, try to mount the filesystem with the same options on the 11.00 box.

Hope this kind of helps :-)

Hey Folks,

Thanks for all the great suggestions. I was actually able to get it resolved using the pfs_mount command and experimenting with some switches.

Thans for all the input and for getting me on the right track!
