Environment

Novell Open Enterprise Server 2 (OES 2) Linux
Novell Open Enterprise Server 11 (OES 11) Linux

Situation

With Novell Open Enterprise Server (OES) and Novell Storage Services (NSS), NSS uses a Virtual File System (VFS) which acts as a /proc type file system, and is used to interact with the NSS kernel modules.

During a shutdown sequence of the server, the following message is observed :

Could not find /_admin in mtab
umount: /_admin: not mounted

Oops: umount failed :-( -- trying to remount readonly...
extra sync...
... hope now it's ok to reboot.


The reported error is cosmetic of nature.

Resolution

The /etc/init.d/boot.localfs script has been fixed to properly handle an already unmounted file system.

Cause

The root cause for this error was the system attempting to unmount this nssadmin file system twice.

The first time this was unmounted successfully, where during the second attempt the reported error was displayed.
