device-mapper: remove ioctl on failed: Device or resource busy

This document (7017390) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 Service Pack 4 (SLES 11 SP4)

Situation

On a system with root on lvm during shutdown (or reboot) the following messages are shown:

Unmounting file systems
done
device-mapper: remove ioctl on failed: Device or resource busy
device-mapper: remove ioctl on failed: Device or resource busy
device-mapper: remove ioctl on failed: Device or resource busy

The shutdown completes without any hangs.

Resolution

The device-mapper update, device-mapper-1.02.77-0.15.14, released July 2016 includes the patch to resolve this problem.
Please install the recommended update.

Cause

The messages are because /etc/init.d/boot.lvm calls 'vgchange -a n', which obviously fails on the /dev/system/root as that is still mounted.
