[opensuse] Can't mount NFS
OpenSUSE Tumbleweed 20181116 My NFS recently stopped working and I don't know why. I haven't changed anything.

My NFS recently stopped working and I don't know why. I haven't changed anything. Here is what happens when I try a local mount (I'm on madhatter 192.168.2.1):
root@madhatter:~# exportfs /home 192.168.0.0/255.255.0.0 /software 192.168.0.0/255.255.0.0 /multimedia 192.168.0.0/255.255.0.0
what is the full contents of /etc/exports?
root@madhatter:~# mount 192.168.2.1:/home/mounts/build /mnt mount.nfs: requested NFS version or transport protocol is not supported root@madhatter:~#
mount -v might show more information.
In the output of journalctl -f I get:
Nov 18 22:44:07 madhatter rpc.gssd[948]: ERROR: can't open nfs/clnt1b/info: Invalid argument Nov 18 22:44:07 madhatter rpc.gssd[948]: ERROR: failed to parse nfs/clnt1b/info Nov 18 22:44:07 madhatter rpc.gssd[948]: ERROR: can't openat nfs/clnt1b: No such file or directory Nov 18 22:44:07 madhatter rpc.gssd[948]: ERROR: can't openat nfs/clnt1b: No such file or directory
What is this? I do have Kerberos set up but I'm just trying to do a mount without Kerberos. I'm not sure what this rpc.gssd process is or whether it is screwing things up.
I don't know either but google quickly finds http://man7.org/linux/man-pages/man8/gssd.8.html so I strongly suspect its something to do with kerberos. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I disabled krb5kdc and kadmind with systemctl disable krb5kdc systemctl disable kadmind and removed the package gssproxy (don't know if this made any difference) and rebooted and my nfs server is back up: ssimpson@madhatter:~$ lsmod |grep nfs nfsd 425984 9 nfs_acl 16384 1 nfsd lockd 118784 1 nfsd grace 16384 2 nfsd,lockd auth_rpcgss 73728 3 nfsd,rpcsec_gss_krb5 sunrpc 421888 19 nfsd,auth_rpcgss,lockd,rpcsec_gss_krb5,nfs_acl ssimpson@madhatter:~$ rpcinfo -p |grep nfs 100003 3 tcp 2049 nfs 100003 4 tcp 2049 nfs 100227 3 tcp 2049 nfs_acl 100003 3 udp 2049 nfs 100227 3 udp 2049 nfs_acl ssimpson@madhatter:~$ Therefore, my conclusion is that some update decided since I was running Kerberos, my nfs shares should be Kerberized. Changing the behavior when I haven't modified any files doesn't sound like a sound strategy. Anyways, that's what I get for running a bleeding edge distribution (Tumbleweed). Happy that my automounts and nfs are running again. On 11/19/18 11:47 AM, Scott Simpson wrote:

My NFS recently stopped working and I don't know why. I haven't changed anything.
And you did not install any updates? Try to recall when it started, check what updates were installed before; try to boot from snapshot preceding these updates.
Here is what happens when I try a local mount (I'm on madhatter 192.168.2.1):
root@madhatter:~# exportfs /home 192.168.0.0/255.255.0.0 /software 192.168.0.0/255.255.0.0 /multimedia 192.168.0.0/255.255.0.0 root@madhatter:~# mount 192.168.2.1:/home/mounts/build /mnt mount.nfs: requested NFS version or transport protocol is not supported root@madhatter:~#
In the output of journalctl -f I get:

What is this?
As far as I can tell this simply means that NFS connection went away. I'd start with sniffing network - is there any traffic between client and server at all? Run tcpfump/tshark/wireshark with suitable packet size (you can actually set it to 1500 to capture full packets) during mount and upload somewhere.
I do have Kerberos set up but I'm just trying to do a mount without Kerberos. I'm not sure what this rpc.gssd process is or whether it is screwing things up.

There have been reasons to use that, but given that Scott's setup used to work, that is most likely not a solution here. -- Per Jessen, Zürich (1.2°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I mean that an update may have changed the default assumptions - he is runnin gTW, after all. I do not mean to use fstab, but there will be a way to specify nfs version in the command line.

Correction, as a mount option, it means 4, then 3.

True, I ignored that.

Yes, same as in fstab. -- Per Jessen, Zürich (1.1°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
