Okay, it took a few minutes, but I figure it out. Seems that Scientific Linux eems to regress a bit in this area.
With Centos, you need to bind like so: /home/share /exports/share none bind 0 0 /home/vhosts /exports/vhosts none bind 0 0 And then specify the options (including fsid0): in /etc/exports /exports *(rw,fsid=0,insecure,no_subtree_check,sync,no_root_squash) /exports/vhosts *(rw,fsid=0,insecure,no_subtree_check,sync,no_root_squash) /exports/share *(rw,fsid=0,insecure,no_subtree_check,sync,no_root_squash) [root@centos home]# In order for clients to mount via NFS4 (with all the usual stuff about specifying in the ports in /etc/sysconfig/nfs) in thisfmat : mount -t nfs4 192.168.15.200:/ /mnt Which is apparently the correct way of mount via NFS HOWEVER, in Scientific Linux, you can get way with a) not binding the directories and b) go back to this format: /home/exports *(ro,sync) /opt *(ro,sync) And still be able to mount: mount -t nfs4 192.168.15.100:/opt /mnt I have to double check the mounts to confirm that I am mount via NFS4. Centos box (mounting SL box via NFS4): 192.168.15.100:/opt /mnt nfs4 rw,addr=192.168.15.100 0 SL Box (mounting Centos box via NFS4): 192.168.15.200:/ /mnt nfs4 rw,addr=192.168.15.200,clientaddr=192.168.15.100 0 0 Huh. Thanks a lot for the pointers, guys. It has been interesting. :) On Jun 2, 2011, at 8:50 PM, RILINDO FOSTER wrote: > Here you go.
