In that case, SL 6.x (and maybe Red Hat 6.x) is breaking convention here. Make it easier for old-school admins like me, though. :) - Rilindo ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I was going based on this: http://www.brennan.id.au/19-Network_File_System.html#nfs4 but I didn't pay close attention to where fsid is only specified once fixed.

[CentOS] SOLVED (was Re: Unable to mount Centos 5.6 Server via nfs4 - Operation Not Permitted - MADNESS!
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 nonebind0 0 /home/vhosts/exports/vhosts nonebind0 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.
