Hello
I now know the reason for this failure, and like to share it, if anybody
else gets the same message. All the servers where I have this problem
have one thing in common. They have all a filesystem mounted from
another server by a standard nfs mount. The nfs server had a IP change a
couple of weeks ago. During that IP change, the clients still hold their
mount against the old IP. When the nfs server came up on it's new IP, we
had to force an unmount and then a mount of the filesystem. After the
remount, everything looked good, but something hold a reference to the
old nfs mount alive. The applications running on the servers where SAP.
I restarted some of the servers, and this solved the problem. But on the
last server, the SAP team did a controlled shutdown of application. And
this solved my problem aswell. So if you get this problem, and had a IP
change on a nfs server, try to search for an application holding a
reference to the old filesystem.
