NFS on CentOS 6 can talk to Centos 5 but not Centos 6 clients
My setup is running nfs and nis. The CentOS 6.x client can't mount CentOS 6.x machine, but can connect fine to a CentOS 5.x. The CentOS 5.x machine can also mount a CentOS 6.x machine fine.
mount.nfs compton:/compton /temp -vvv mount.nfs: trying text-based options 'vers=4,addr=9.9.9.9,clientaddr=9.9.9.31' mount.nfs: mount(2): Connection refused Iptables disabled SElinux disabled /etc/exports: Code:
/compton @nis1(rw,sync,nohide,root_squash) @nis2(rw,sync,nohide,root_squash) |
#1, never disable SELinux, set it to permissive mode, but dont disable it.
#2. you are being refused connection, that means a user, permission, IP range, etc... something along that line is bad. This is not a NFS issue, but a network permissions issue. #3. you also do not have any fsid for the exports. that can cause a permissions issue. #4. try mount -t nfsv4 instead of mount.nfs #5. have you run exportfs -a |
So it looks like an incompatibility with NFS3 vs NFS4. My CentOS 5.x machines have been running this config for years without issue. As soon as I moved to CentOS 6.x, they default to NFS4. I can force NFS3, but this is not the solution I was hoping for.
On most systems I can do cd /nfs/compton1 for compton:/compton/disk1 This is accomplished via an auto.nfs. In the end, forcing nfs to mount version 3 in the auto.nfs file fixed Code:
# Issue the output string that autofs needs to make the mount |
