Cannot rezise root lvm - Logical volume is not mounted but is in use

[Mauricio Farell Perezgrovas]

Extending or resizing a root Logical volume fails with system-config-lvm but not if done with command line.

How to reproduce:
1. Open system-config-lvm
2. Try to resize or extend root partition
3. Fails every time with error: "Logical volume is not mounted but is in use. Please close all applications using this device (eg iscsi)

All operations can be made without a problem with command line:

lvextend -L +10G /dev/VolGroup00/root
resize2fs /dev/VolGroup00/root

Version: system-config-lvm 1.1.18

Status changed to 'Confirmed' because the bug affects multiple users.

[Vicente Ramirez-Perea (victealias)]

I have the same symtoms but on a volume that is not root.
I also can resize lv from cli (with lvextend and resize2fs, but not with the system-config-lvm gui.
I confirm with lsof, fuser, umount and stoping services related with the volume that there was nothing using it.

I see the same thing on a volume mounted at /home.

This seems to be because system-config-lvm expects readlink to be /usr/bin/readlink, but it is (now) /bin/readlink. As a temporary bodge I have added a link from /usr/bin/readlink to /bin/readlink which allows system-config-lvm to work correctly.

The attachment "[PATCH] Change readline location to /bin/readline in utilities.py as it is no longer present in /usr/bin" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.
