[linux-lvm] grow lv bug



This seems to be a bug with lvm. Unable to grow the logical volume.
I have the space. pvextend succeeded, vgextend succeeded but lvextend, 
lvresize fail.

Where can I report this and get some support?

Following is a transcript of my attempt to solve this problem. I've remove the 
sda stuff as it has no problems.

Running Logical Volume Manager gui and attempting to extend the 
volume results in the same error.

All I can see is the log message, but it doesn't help me to solve the problem 
and the error message seems to be wrong. Where can I report this bug?

Thanks Hugh.
