NFSv4 on CentOS 4.5
Hi. I'm having trouble accessing a shared directory over NFSv4 on a CentOS 4.5 machine. My export file reads /test 10.0.0.0/255.0.0.0(ro,async,insecure,nohide,no_subtree_check) Running the mount command with NFSv4 as the filesystem gives me a permission denied error.

nfsv4 and kerberos - fails to mount
I have been trying all sorts of things to get this working. nfsv4 works fine if I just use the nfs-v3 form of export i.e. /nfs4exports 192.168.230.237/24(ro,fsid=0,sync,insecure,no_root_squash,no_subtree_check,squash_uids=0-99) /nfs4exports/NDG 192.168.230.237/24(rw,insecure,no_subtree_check,nohide,sync,no_root_squash,squash_uids=0-99) but this is inherently open to all on this machine. so then using this recipe http://www.techrepublic.com/blog/opensource/kerberos-authentication-with-nfsv4/1965 and man...

Mounting NFS subdirectories individually or just the parent?
There is a slight performance related reason for exporting disk partitions individually, the performance boost is server-side as Paul says. The advantage is that the no_subtree_check can be used without any additional security risk. It is probably the case that the /export/base/a is a partition, is exported with no_subtree_check, and therefore there is a small performance boost. Preventing server side mount point traversal can also form part of a security mechanism if servers...

bug resolve yet for export OCFS2 volume to NFS client ?
...ordirplus mount option. This disables the READDIRPLUS RPC call to workaround a bug in NFSD, detailed in the following link: http://oss.oracle.com/pipermail/ocfs2-announce/2008-June/000025.html Users running NFS version 2 can export the volume after having disabled subtree checking (mount option no_subtree_check). Be warned, disabling the check has security implications (documented in the exports(5) man page) that users must evaluate on their own. is it being fixed with centos 5.3 (2.6.18-164.11.1.el5)? anything I need to aware for exporting OCFS2 volume via NFS? -- Thomas Lau Infrastructure Delivery...

I tried your NFS translation fix via idmapd.conf? but that isn't working for me. I've discovered that's because CentOS 7 is using gssproxy so apparently your fix won't work.
