Re: [Freeipa-users] Stale NFS file handle
You can get authentication failure if the user's home is on a NFS which is failing to re-mount. The stale NFS handle usually means the NFS server changed fsid of the exported volume after its reboot. This usually happens if you are exporting a LVM partition via NFS. The workaround is to specify fsid of the exported volume manually in /etc/exports HTH, Ondrej On 09/12/2012 08:26 PM, george he wrote: Hello, My ipa server and my nfs server are the same machine running centos 6.3.

Re: [Freeipa-users] Stale NFS file handle
What nfs version are you using? And if 4, do you use kerberos? We are using mostly nfs 3 still, and those nfs mounts just reconnect by themselves up to a few minutes after the nfs server is back online.

I tried umount but without -l, it said drive busy. Next time I will try with -l.

[Freeipa-users] Stale NFS file handle
Hello, My ipa server and my nfs server are the same machine running centos 6.3. The server was accidentally down and rebooted. But then I got "authentication failsure" on some clients when tried to log on through gdm, and blue screen (no desktop, no panels) on some others. On some clients that I was on before the server was downthe, I got "Stale NFS file handle". Yet on some other clients, everything is fine. All clients are running centos 6.3, too. Is there a way (e.g. restarting some services) to get the above problems away instead of rebooting the clients?
