Another OpenSolaris box by default tries to mount using NFSv4, while your ESXi NFS client is trying NFSv3. You might want to try either NFSv3 from another OpenSolaris box, or force NFSv4 (if it is possible) on ESXi side. > > The solaris box (solar) is on 10.0.0.50 > The ESXi server is on 10.0.0.52 > The NFS export is /tank/nfs/vm1 > > The vm1 directory is globally readable and writable. > drwxrwxrwx 2 jamesb staff 2 2009-06-19 22:12 vm1 > > I set up the share using: zfs set sharenfs=rw=10.0.0.52,root=10.0.0.52 > tank/nfs/vm1 > I have also tried without the rw option, and without the root option, > without any luck. > > # showmount -e > export list for solar: > /tank/nfs/vm1 10.0.0.52 > (or, if I removed the rw and root options I get: /tank/nfs/vm1 (everyone)) > > # sharemgr show -vp > default nfs=() > zfs > zfs/tank/nfs/vm1 nfs=() nfs:sys=(rw="10.0.0.52" root="10.0.0.52") > /tank/nfs/vm1 > > Snoop shows the following: > 10.0.0.52 -> solar TCP D=111 S=755 Syn Seq=2233513954 Len=0 > Win=65535 Options=<mss 1460,nop,wscale 1,nop,nop,tstamp 3586045 0,sackOK,eol> > solar -> 10.0.0.52 TCP D=755 S=111 Syn Ack=2233513955 > Seq=3630673266 Len=0 Win=49232 Options=<nop,nop,tstamp 3214393 3586045,mss > 1460,nop,wscale 0,nop,nop,sackOK> > 10.0.0.52 -> solar TCP D=111 S=755 Ack=3630673267 Seq=2233513955 > Len=0 Win=33304 Options=<nop,nop,tstamp 3586045 3214393> > 10.0.0.52 -> solar PORTMAP C GETPORT prog=100005 (MOUNT) vers=3 > proto=TCP > solar -> 10.0.0.52 TCP D=755 S=111 Ack=2233514059 Seq=3630673267 > Len=0 Win=49128 Options=<nop,nop,tstamp 3214393 3586045> > solar -> 10.0.0.52 PORTMAP R GETPORT port=34596 > 10.0.0.52 -> solar TCP D=111 S=755 Fin Ack=3630673299 > Seq=2233514059 Len=0 Win=33304 Options=<nop,nop,tstamp 3586045 3214394> > 10.0.0.52 -> solar TCP D=34596 S=756 Syn Seq=82774780 Len=0 > Win=65535 Options=<mss 1460,nop,wscale 1,nop,nop,tstamp 3586045 0,sackOK,eol> > solar -> 10.0.0.52 TCP D=755 S=111 Ack=2233514060 Seq=3630673299 > Len=0 Win=49232 Options=<nop,nop,tstamp 3214394 3586045> > solar -> 10.0.0.52 TCP D=756 S=34596 Syn Ack=82774781 > Seq=3630723273 Len=0 Win=49232 Options=<nop,nop,tstamp 3214394 3586045,mss > 1460,nop,wscale 0,nop,nop,sackOK> > solar -> 10.0.0.52 TCP D=755 S=111 Fin Ack=2233514060 > Seq=3630673299 Len=0 Win=49232 Options=<nop,nop,tstamp 3214394 3586045> > 10.0.0.52 -> solar TCP D=34596 S=756 Ack=3630723274 Seq=82774781 > Len=0 Win=33304 Options=<nop,nop,tstamp 3586045 3214394> > 10.0.0.52 -> solar TCP D=111 S=755 Ack=3630673300 Seq=2233514060 > Len=0 Win=33303 Options=<nop,nop,tstamp 3586045 3214394> > 10.0.0.52 -> solar MOUNT3 C Mount /tank/nfs/vm1 > solar -> 10.0.0.52 TCP D=756 S=34596 Ack=82774889 Seq=3630723274 > Len=0 Win=49124 Options=<nop,nop,tstamp 3214394 3586045> > solar -> 10.0.0.52 MOUNT3 R Mount Permission denied > 10.0.0.52 -> solar TCP D=34596 S=756 Fin Ack=3630723306 > Seq=82774889 Len=0 Win=33304 Options=<nop,nop,tstamp 3586046 3214395> > solar -> 10.0.0.52 TCP D=756 S=34596 Ack=82774890 Seq=3630723306 > Len=0 Win=49232 Options=<nop,nop,tstamp 3214395 3586046> > solar -> 10.0.0.52 TCP D=756 S=34596 Fin Ack=82774890 > Seq=3630723306 Len=0 Win=49232 Options=<nop,nop,tstamp 3214395 3586046> > 10.0.0.52 -> solar TCP D=34596 S=756 Ack=3630723307 Seq=82774890 > Len=0 Win=33303 Options=<nop,nop,tstamp 3586047 3214395> > > Can anyone help or suggest where I might look next?
