Hi,
Using nfs (v4 on CentOS 5.5) on top of mfs is definitely silly.
However, some applications that I plan to use can run only with nfs,
so I tried to export mfs mount point as an nfs export. For easiness,
right now I am not using any iptables rules on any node.
On the nfs server (10.1.2.22, at the same time, as a mfs client):
# cat /etc/exports
/mnt/mfs 10.*(rw,no_root_squash)
# df | grep mfs
mfs#10.1.2.22:9421 on /mnt/mfs type fuse (rw,allow_other,default_permissions)
On the nfs client (10.1.2.24):
I got the following error.
# mount -t nfs 10.1.2.22:/mnt/mfs /mnt/nfs_mfs/
mount: 10.1.2.22:/mnt/mfs failed, reason given by server: Permission denied
# tail /var/log/messages
Dec 23 14:23:23 host1a mountd[17279]: authenticated mount request from
10.1.2.24:805 for /mnt/mfs (/mnt/mfs)
Dec 23 14:23:23 host1a mountd[17279]: Cannot export /mnt/mfs, possibly
unsupported filesystem or fsid= required
Is there anyone who knows a workaround?
Thanks,
-Jun


---------------------------------
hi,may be you can change /etc/exports like this

/mnt/mfs/test    *(rw,fsid=10)

Thanks,
