[OpenIndiana-discuss] NFS mount of oi_148 filesystem by Linux fails

[Martin Frost]

I'm trying to export a ZFS filesystem on oi_148 via NFS, but the NFS
mount fails.  The same ZFS filesystem is shared via CIFS, and that's
working.  I hope CIFS sharing doesn't interfere with NFS exporting.

Here's the setup, where my nfs server is 'nfsserver', the filesystem
I'm trying to mount is '/nfsclient/filesys', and my nfs client is
'nfsclient' (which is running Linux):

  11;nfsserver/root# svcs -a | grep nfs | grep server
  online         Feb_27   svc:/network/nfs/server:default

  12;nfsserver/root# zfs get sharenfs nfsclient/filesys
  NAME         PROPERTY  VALUE                          SOURCE
  nfsclient/filesys  sharenfs  sec=sys,rw=nfsclient.stanford.edu  local

  13;nfsserver/root# zfs get sharesmb nfsclient/filesys
  NAME         PROPERTY  VALUE       SOURCE
  nfsclient/filesys  sharesmb  name=filesys  local


  37;nfsclient/etc# showmount -e nfsserver
  Export list for nfsserver:
  /nfsclient/fs100  (everyone)
  /var/smb/cvol (everyone)
  /nfsclient/filesys  nfsclient.stanford.edu

And here's the mount failure:

  40;nfsclient/etc# mount  nfsserver:/nfsclient/filesys /etc/testmount
  mount.nfs: access denied by server while mounting nfsserver:/nfsclient/filesys

I don't know if NFS in OI references /etc/hosts.allow on the NFS
server, but just in case I gave the nfsclient ALL access in that file
(to no avail).

I can't find any log entries relating to this NFS mount failure,
even after I enabled info and debug logging in syslog.conf.

The two machines are on the same subnet.  I can ssh between them.

What might I be missing here?


I have anther OI machine where NFS exporting to Linux machines is
working fine, and I even see a mountd error message in
/var/adm/messages on that machine.


(Side notes: This isn't a problem, but the filesystem /nfsclient/fs100
isn't exported or mountable, though it shows up in 'showmount -e'.
And I haven't exported /var/smb/cvol, but it is mountable -- maybe
that's a default related to using Samba; there's only one file in it:
/var/smb/cvol/windows/system32/eventlog.dll)


Thanks,
Martin
