Hi, I have an nfs server called "server" in this scenario. This server is running 9.1-PRERELEASE and exports 70+ zfs datasets over NFSv3. I sent an email a month ago, that half of the krb5i mounts fails over tcp. I noticed, that with simple krb5 sec flavour fever of the mounts are failing. I expected, that with sec=sys none will fail. Unfortunately this is not the case. I can get a failed mount with sec=sys to within 2 minutes. See the attached bash script. Within 2 minutes I always get this: mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 10.1.2.3 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=6 mount.nfs: trying 10.1.2.3 prog 100005 vers 3 prot TCP port 719 mount.nfs: mount(2): Input/output error mount.nfs: mount system call failed As soon as I have some time, I'll hook a wireshark and see the trace, what's going on the wire. If you have any ideas how to approach this, please do not hesitate to tell me. Thanks, Attilahelp
