RPC Timed out: mount Linux 6.2 file system from Solaris 2.6

[Patrick Hu]

I can mount a Linux 6.2 file system from a SunOS 5.5.1 machine.
but I got a RPC Timed out error from a SunOS 5.6.

NFS server (Redhat 6.2):
# more /etc/exports
/usr2 solaris_nfs_client(rw,no_root_squash)

NFS client (SunOS 5.6)
# mount -F nfs -o rw linux_nfs_server:/usr2 /usr2
nfs mount :linux_nfs_server : : RPC: Timed out
nfs mount: retrying: /usr2
nfs mount: linux_nfs_server: : RPC: Timed out

Any advice?

TIA

Linux (RedHat 6.2) Only talks NFS v2.0, Solaris assumes V3.0.

You need to mount using:

# mount -F nfs -o rw,vers=2 linus_nfs_server:/usr2 /usr2

Solaris doesn't assume NFS version 3 by default. It uses the version
that is "the highest one available on both systems". So, if Solaris is
trying to use NFS version 3, it is because Linux is saying that version
is available. (Otherwise, Solaris wouldn't succeed in mounting from
other systems that support only NFS version 2.)

Nevertheless, one solution *is* to use the 'vers=2' mount option...

I assumed Solaris was using Version 3 when I first saw this. However I
am quite prepared to belive Linux says "I do version 3" and then does
not!

Thanks for explaining this, we learn something every day ...
