Mount a remote file system

Hello,

I'm having troubles with sharing a filesystem across 2 machines...

Machine A, running Solaris 10, is sharian via NFS the filesystem /sp.

Machine B, running Solaris 10, is mounting /sp shared by A in /tm/sp and shares via NFS the /tm folder.

Machine C, running HP-UX, is mounting /tm from machine B in /mnt.

The problem is that fom machine C is is not possible to access /mnt/sp. It is listed as empty.

Could you please help?

Thank you!

Maybe that's a (intended) limitation of NFS in Solaris 10*. Maybe you have to set some option in order to export a filesystem across filesystem borders. For performance reasons you should mount /sp from machine A directly on C (way over B doubles network load and esp. locking latency).

Despite some special situations mounting /tmp via NFS is not that good as
(i) it's not possible to have sockets on NFS (some apps depend on such things in /tmp)
(ii) some apps do write quite heavily to /tmp (and get slow that way)
(iii) if some system deamon uses a temp file and your network breaks or gets slow your system gets into trouble

* to find out whether solaris or hp-ux doesn't do it: can you mount B:/tm on A (in some other directory)?

Hello,

It's not a problem of HP-UX... Is the same behavior with 3 Solaris machine...

More details...

"sp" is a ZFS Pool having the following Filesystems:

/sp/int
/sp/trans

All 3 are shared in the same way via NFS.

If I try to mount from machine A to B the /sp I will not be able to access the content of /sp/int nor /sp/trans.
But if I will mount from machine A to B the /sp/trans then the content is visible. Same for /sp/int...

Jut discover this...
