Tips and tricks: Why do I see "VFS: Busy inodes after unmount" messages in my syslog?
Why do I see this message in my syslog: “kernel: VFS: Busy inodes after unmount. Self-destruct in 5 seconds. Have a nice day…”? There is a condition in both Red Hat Enterprise Linux 3 and Red Hat Enterprise Linux 4 where the kernel fails to properly clean up inodes after an NFS filesystem is unmounted. When this happens, the above message is printed to the /var/log/messages file.
