Bug Description
Binary package hint: lvm2
My system is running 2.6.31-20-generic #57-Ubuntu SMP AMD64 (current karmic-proposed).
Below is the series of commands executed on my logical volumes, two of them currently open were extended 20GB (prior to file system resize), and then I wanted to consume the remaining extends on one of them.
Prior to executing these commands I removed two other existing volumes in the same group order to free up the space.
My pv's sit on top of a RAID1 md device as shown below, similar to a debian report here: http://

It may be worth noting my RAID1 was degraded at the time I executed these commands.
For the keen observer noting the three-disk RAID1 setup, RAID1 provides a convenient method to backup and sync home directories to a second laptop via an external eSATA enclosure.
