NFS server on embedded plateform : "possibly unsupported filesystem or fsid= required
Hi,
I am working on a NFS server embedded on a PowerPC plateform (4650EX, 512Ram, 1 GB Ethernet)
but i can't mount my exports folders from my client. Here are messages :
-- server side :
$ tail /var/log/message
Dec 11 23:35:45 canyonlands mountd[1345]: authenticated mount request from 147.138.27.17:620 for /mnt/ssd (/mnt/ssd)
Dec 11 23:35:45 canyonlands mountd[1345]: Cannot export /mnt/ssd, possibly unsupported filesystem or fsid= required
-- client side :
$ moutn -t nfs 147.138.27.20:/mnt/ssd /mnt/nfs
mount: 147.138.27.20:/mnt/ssd failed, reason given by server: Permission denied
-- Lunch of the NFS services
$ /etc/init.d/nfs start
Starting NFS services: [ OK ]
Starting NFS daemon: NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directory
[ OK ]

Here some files conf :
$ cat /etc/exports
/mnt/ssd 147.138.0.0/16(rw,fsid=0,no_root_squash)
$ showmount -e 147.138.27.20
