NFS mounts to a RHEL 4u3-64 server receive "Permission denied" errors. $ mount -t nfs -o rw nfsserver:/mnt/disk1 /mnt/disk1/ mount: nfsserver:/mnt/disk1 failed, reason given by server: Permission denied /etc/exports: /mnt/disk1/ nfsclient(rw,no_root_squash) /mnt/disk2/ nfsclient(rw,no_root_squash) Restarting portmap, nfslock and nfs on nfsserver have no impact. rpc.mountd _seems_ to allow it: (from messages) May 13 15:01:57 nfsserver rpc.mountd: authenticated mount request from nfsclient.domain.com:617 for /mnt/disk1 (/mnt/disk1) One peculiar thing is that the 'sunrpc' module is not automatically loaded on nfsserver after a reboot. Until I manually mount the rpc_pipefs filesystem, I receive "RPC MTAB table not found" (not verbatim). After I mount the pipefs filesystem, I no longer get this error, but I still cannot mount any filesystems off of nfsserver. mount -t rpc_pipefs sunrpc /var/lib/nfs/rpc_pipefs One other piece of info that might be worthwile, every time I stop the nfs services on the server, in messages there are a few lines that look strange: May 13 15:13:12 nfsserver kernel: nfsd: last server has exited May 13 15:13:12 nfsserver kernel: nfsd: unexporting all filesystems May 13 15:13:12 nfsserver kernel: rpciod: active tasks at shutdown?!

No iptables firewall is in place. The nfsclient can mount nfs mounts from other nfs servers, but no client can mount from this server. Things Ive tried: Specifying the fqdn in the mount command Specifying nfsvers=3, udp, tcp Replacing 'nfsclient' with '*' in /etc/exports Restarting portmap, nfslock, nfs after every change Running exportfs -r after every change to /etc/exports What am I missing? -- Jeff Macfarland (jmacfarland@xxxxxxxxxxxx) Nexa Technologies - 972.747.8879 Unix Administrator GPG Key ID: 0x5F1CA61B GPG Key Server: hkp://wwwkeys.pgp.net -- amd64-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/amd64-list
