(solved) unmount home failed

[errol]

I am trying to change my /Home from ext3 to ext 4 without formating. I tried to base the change on this article:
http://www.debian-administration.org...xt4_filesystem

The first requisite is to unmount the home drive. Whan attempting to unmount /home I get the following:


errol@errol-linux:~$ sudo umount /home/
[sudo] password for errol:
umount: /home: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
errol@errol-linux:~$ sudo umount /dev/sda5
umount: /home: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))


What can I do to enable the un-mount. I don't understand the "lsof" or "fuser" reference.

Re: unmount home failed

You cannot unmount /home if you are booted (and logged into) multiuser environment, as the /home filesystem is in use (busy).

Boot into recovery mode (single user environment) to unmount home and perform the operations (or use a livecd to work with the filesystem). If you don't have another computer to access the internet, write the steps to convert down if you boot into recovery mode.

Thank you Kubicle. I'll boot into recovery mode.
