Since you had two different things mounted on /home, it is unclear how the system would interpret "umount /home". That is why I did not suggest doing that. From the error, it seems that some checks got bypassed and a busy filesystem was disconnected. It is likely that there is now some filesystem corruption on /dev/vdb, and you should reboot with a forced fsck to clean it up. You really should track down the cause of the extra mount of /dev/vdb on /home first, or the system will just come up wrong again. -- Bob Nichols "NOSPAM" is really part of my email address.
